While modern ECF plants can achieve chlorinated organic compounds (AOX) emissions of less than 0.05 kg per tonne of pulp produced, most do not achieve this level of emissions. Within the EU, the average chlorinated organic compound emissions for ECF plants is 0.15 kg per tonne. However, there has been disagreement about the comparative environmental effects of ECF and TCF bleaching. On the one hand, paper and chemical industry-funded studies have generally found that there is no environmental difference between ECF and TCF effluents. On the other hand, an independent peer-reviewed study has found that, comparing conventional, ECF and TCF effluents before and after secondary treatment, “TCF effluents are the least toxic”.

For many years leading up to the early 1990s, Medellín had been growing rapidly as large quantities of people moved into the Metropolitan Area of the Aburrá Valley in hopes of taking advantage of economic opportunities. With so little open space, those who urbanized did so very near or alongside the Medellín River. This led to an increase in municipal runoff. These domestic effluents compounded with growing industrial effluents, and upstream agriculture activity effectively increased toxic runoff into the Medellín River to the level that required immediate and drastic measures to recuperate the river.

Forward osmosis (FO) has many positive aspects in the treating of industrial effluents containing many different kinds of contaminants and also in the treating of salty waters. When these draw effluents have moderate to low concentrations of removable agents, the FO membranes are really efficient and have the flexibility of adapting the membrane depending on the quality desired for the product water. FO systems are also really useful when using them combined with other kinds of treatment systems as they compensate the deficiencies that the other systems may have. This is also helpful in processes where the recovery of a certain product is essential to minimize costs or to improve efficiency such as biogas production processes.

All effluents discharged to closed or semi-closed water bodies, such as Tokyo Bay, Osaka Bay, or Lake Biwa, are further treated to tertiary level. This applies to about 15% of waste water. The effluent quality is remarkably good at 3–10 mg/l of BOD for secondary-level treatment, well below the national effluent standard of 20 mg/l.

They have an affinity for organic and inorganic pollutants, which has led to an interest in using them as sorbents for the treatment of effluents and polluted water. Hydrous iron oxides include ferrihydrite, akaganéite, feroxyhyte, goethite, lepidocrocite and limonite. They may also be precipitated in highly porous poorly crystaline or amorphous forms and therefore be good adsorbents used eg in water treatment.

This can lead to unintended ecological consequences. For instance, fish exposed to treated sewage effluents were found to have concentrations of the synthetic hormone levonorgestrel in blood plasma higher than those found in humans taking hormonal contraceptives. Because the antigens used in contraceptive vaccines are protein, not steroids, they are not easily passed from animal to animal without loss of function.

Río Pilcomayo The gradual decrease in Bolivia's water quality is due to the release of untreated effluents from industries and cities. For example, in the Andean region, rivers transport high values of organic material, up to 100 mg/l. This water is used for irrigated agriculture downstream. In the Amazon region, erosion and land use upstream, especially mining, deteriorate water quality due to high concentration of sediments.

A domestic wastewater effluent, mixed with seawater, was the nutrient source for phytoplankton, which in turn became food for oysters and clams. They cultivated other organisms in a food chain rooted in the farm's organic sludge. Dissolved nutrients in the final effluent were filtered by seaweed (mainly Gracilaria and Ulva) biofilters. The value of the original organisms grown on human waste effluents was minimal.
|
|
Besides this, several heavy industries were also set up in the city. Since 1930, the lake has gradually started receiving sewage and industrial effluents through the feeder nullahs. The Picket Nalla discharges mostly domestic sewage throughout the year into the lake from the north-eastern side. Similarly the Banjara Nalla (from north-western side) and Balkapur Nalla (from western side) discharge mostly domestic sewage into the lake.

The flotation process is also widely used in industrial waste water treatment plants, where it removes fats, oil, grease and suspended solids from waste water. These units are called dissolved air flotation (DAF) units. In particular, dissolved air flotation units are used in removing oil from the wastewater effluents of oil refineries, petrochemical and chemical plants, natural gas processing plants and similar industrial facilities.

Other taboos such as not washing, bathing or throwing effluents into the Lake that were formerly strictly observed, aided in maintaining the purity and health of the Lake. Unfortunately, these taboos are not observed by residents or visitors due to their weak implementation by the Abono Traditional Council. There are current environmental concerns, including overfishing and inadequate farming methods. The growing population increased demand for fish.

Many industrial effluents contain toxic metals that must be removed. Removal can be accomplished with biosorption techniques. It is an alternative to using man-made ion-exchange resins, which cost ten times more than biosorbents. The cost is so much less, because the biosorbents used are often waste from farms or they are very easy to regenerate, as is the case with seaweed and other unharvested biomass.

Domestic sewage, industrial effluents, agricultural runoff, and mismanaged solid waste are polluting surface and groundwater, especially in Java. Indonesia ranks among the worst countries in Asia in sewerage and sanitation coverage. Few Indonesian cities possess even minimal sanitation systems. The absence of an established sanitation network forces many households to rely upon private septic tanks or to dispose of their waste directly into rivers and canals.

Contradictory views exist on the suitability and safety of RAS effluents to sustain plant growth under aquaponics condition. Future conversions, rather ‘upgrades’, of operational RAS farms to semi-commercial Aquaponic ventures should not be deterred by nutrient insufficiency or nutrient safety arguments. Incentivizing RAS farm wastes through semi- commercial aquaponics is encouraged. Nutrients locked in RAS wastewater and sludge have sufficient and safe nutrients to sustain plant growth under aquaponics condition.

It became heavily silted thereby reducing the surface area of the lake. The silt deposited (estimated to be about 2,500,000 cubic metres) was contaminated with effluents (untreated sewage) from the city's drainage system causing intense eutrophication. The ground water surrounding the lake was also found to be highly contaminated and created serious health hazards. The rainwater combined with sewage water flow from the city resulted in the lake water giving off a foul smell.

PhACs can be entered into the environment in two main ways; direct and indirect. Indirect sources are PhACs that have performed their biologically intended effect and are passed onto the environment in either their complete or a modified state. PhAC's can be discharged directly by manufacturers of the pharmaceuticals or effluents from hospitals. However with increasing regulation by local, state and federal regulating agencies, direct discharge is becoming much less of an issue.Heberer. 2002.

Composting is now widely used to treat aerobically solid domestic waste and dried effluents of settling basins. Although compost is not soil, biological processes taking place during composting are similar to those occurring during decomposition and humification of soil organic matter. Organic soils, especially peat, serve as a significant fuel and horticultural resource. Peat soils are also commonly used for the sake of agriculture in nordic countries, because peatland sites, when drained, provide fertile soils for food production.

The Palestinian Authority has also been criticized by environmentalists for not doing more to prevent water pollution. Settlers and Palestinians share the mountain aquifer as a water source, and both generate sewage and industrial effluents that endanger the aquifer. Friends of the Earth Middle East claimed that sewage treatment was inadequate in both sectors. Sewage from Palestinian sources was estimated at 46 million cubic meters a year, and sources from settler sources at 15 million cubic meters a year.

In 1994, a study was conducted testing pollution in the Kishon at sources close to several industrial plants. Decades of dumping hazardous effluents had all but eradicated aquatic life in the river, causing the Israel Union for Environmental Defense (IUED) to file several successful lawsuits against two of the biggest polluters, Deshanim Ltd. And Haifa Chemicals. By 1998, most of Israel's surface water, rivers and streams, as well as its groundwater reserves, were polluted to a certain degree by industrial and civil waste.

A passive treatment system is a method for removing metals from acid mine drainage. There are several types of passive treatment systems, each of which may be used on their own or in combination to treat effluents. The type of system selected is dependent upon the chemistry of the acid mine drainage and the flow of the discharge, as well as State and Federal regulations. Passive treatment systems do not require power and are less expensive than active treatment systems.

Tarmiya was also situated within a large military security zone, thereby needing no additional perimeter security or military defenses at the site. At this same site, the Iraqis built a multimillion-dollar “chemical wash” facility for recovering uranium from refurbished calutron components. This facility was reportedly as sophisticated and clean as any in the West, and triple-filtered so as not to release any trace effluents into the atmosphere that might have led to its detection once it began operation.

Tetraspora species are primarily freshwater organisms which inhabit ecosystems like streams, lakes, rivers, ponds. They can be found in harsh environments like thermal effluents and industrial waste. However, just recently it has been found that Tetraspora species have the ability to adapt and reside in marine environments that are exceptionally nutrient rich and receive freshwater river outflows. Species have been found in both stagnant and free flowing water bodies, although morphology of species between the two water types slightly differs.

BOD reduction is used as a gauge of the effectiveness of wastewater treatment plants. BOD of wastewater effluents is used to indicate the short-term impact on the oxygen levels of the receiving water. BOD analysis is similar in function to chemical oxygen demand (COD) analysis, in that both measure the amount of organic compounds in water. However, COD analysis is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biologically oxidized organic matter.

The climate of Hawaii is typical for a tropical area, although temperatures and humidity tend to be a bit less extreme than other tropical locales due to the constant trade winds blowing from the east. The surrounding waters are affected by effluents generated and released from the islands themselves. Floating plastic garbage is a problem, and refuse from the Great Pacific Garbage Patch affects its beaches. Other pressures on Hawaii's fish population are its fishing industries and whalingWhaling in Hawaii.

Liquid effluents and waste water from medium and large scale charcoal operations should be trapped in large settling ponds and allowed to evaporate so that this water does not pass into the local drainage system and contaminate streams. Kilns and pits, as distinct from retorts and other sophisticated systems, do not normally produce liquid effluent - the by- products are mostly dispersed into the air as vapours. Precautions against airborne contamination of the environment are of greater importance in this case.

The water lost its clarity, the desirable fish populations declined, and masses of dead algae accumulated on the shores of the lake. After significant pollution, the October 5, 1963 issue of the Post Intelligencer referred to the lake as "Lake Stinko". Citizen concern led to the creation of a system that diverted the treatment-plant effluents into nearby Puget Sound, where tidal flushing would mix them with open-ocean water. The diversion was complete by 1968, and the lake responded quickly.

Due to the high industrialization in Erode, a vast number of textile dyeing units and leather processing units came up in the surroundings. Most of these units discharge their untreated effluents into this canal leading to high pollution, causing several health issues to the public. This issue have seen several protests since it heavily damages the underground water potential and agriculture in this area. Along with several social welfare organisations, Erode Municipal Corporation has done a cleaning program to dredge this canal.

The gradual decrease in Colombia's water quality is due to the release of untreated effluents from agriculture, urban settlements and industries. According to Orlando and Arias, there is not a national water quality inventory but rather regional and sporadic studies. For instance the National Planning Division, in a study of 1989 and 1993, estimated that the level of organic material discharged in Colombian water resources is 9,000 BOD per day, of which 4,000 are discharged solely by the agricultural sector.

There is concern that over-exploitation, industrial effluents and sewage wastes are affecting aquifers and surface waters at an alarming rate. As much as 10% of the groundwater resource has been either abandoned or use is restricted due to saline intrusion or pollution. Fifty percent of the unused water resources in the Liguanea Basin serving the Kingston and St. Andrew area are contaminated with nitrates. While water coverage is good at around 95%, reliability of supply to urban households and industrial users is often erratic.

About 346 million tonnes have been extracted throughout history to 2002, and one estimate found that about 109 million tonnes of that remains in use. In 2005, China was the top producer of mercury with almost two-thirds global share followed by Kyrgyzstan. Several other countries are believed to have unrecorded production of mercury from copper electrowinning processes and by recovery from effluents. Because of the high toxicity of mercury, both the mining of cinnabar and refining for mercury are hazardous and historic causes of mercury poisoning.

Caffeine (1,3,7-trimethylxanthine), the substrate in the above reaction, is a purine alkaloid found in a variety of plant species, such as coffee, cacao, cola, and tea leaves. Caffeine has also been used as a cardiac, neurological, and respiratory stimulant. Because of its prevalence in the modern world in the form of beverages, food, and medicine, caffeine has become one of the world's major agro-industrial wastes. Thus, caffeine has become more noticeable in surface water, groundwater, and waste water effluents all over the world.

The Karamana has been facing the problems of pollution, acidification and fish kill in recent years. The causes for the deterioration in the river's water quality include the discharge of untreated sewage and domestic and industrial effluents into the river and the unregulated development of tourism in the river basin area. This has resulted in the lowering of dissolved oxygen levels in the river's water and caused fish kill downstream of the river. Illegal mining of river sand is another significant threat being faced by the river.

The Senne was notorious for being one of Belgium's worst polluted rivers, since all effluents from the Brussels Capital Region emptied into it without treatment. In March 2007, the completion of new sewage treatment plants began to remediate this problem. However, in December 2009, the plant Brussels Nord of Acquiris was temporarily and abruptly shut down, creating a political and ecological crisis. The yellow iris became used as the emblem of the Brussels-Capital Region due to its habitat in the marshy plains around the river.

Other examples of environmental impact in the aquatic environment of human medication concern both cardiovascular and neuro-psychiatric medicines. The non-selective beta- blocking agent Propanolol was found to cause a significant decrease in egg production in Medaka fish, at a concentration close to that demonstrated in the sewage treatment plants (STP) effluents. Gemfibrozil (cholesterol and triglycerides lowering drug) often appears in the effluent from STPs. At concentrations close to those reported in STP effluent, Gemfibrozil lowers the blood levels of testosterone in fish.

The best agricultural land along the Senegal River is in the alluvial valley between Bakel and Dagana, and this area is the most densely populated part of the valley. As the floods retreat each year, a variety of crops (including millet, sorghum, rice, and vegetables) are sown, and they grow and mature quickly. These areas also provide pasture for livestock. But because rainfall has been lower in Guinea in 2006, the water table of the Senegal River and its effluents was at a critical level and comparable to a dry year as of early 2007.

Belize is fortunate to have ample water resources with many rivers and lakes as well as groundwater supplies although specific details about groundwater is not well known. Average daily water use in Belize is similar to that of industrialized countries at around 160 L in rural areas to 280 L in urban areas. Industrial processes encompass the largest demand where about 73% of the freshwater resources end up being used in this sector. Water quality in Belize is mostly good except where industry is discharging effluents in urban areas.

Such DNA modified films can be used for detecting various biomolecules, which would interact with DNA thereby changing electrical conductivity of the diamond film. In addition, diamonds can be used to detect redox reactions that cannot ordinarily be studied and in some cases degrade redox-reactive organic contaminants in water supplies. Because diamond is mechanically and chemically stable, it can be used as an electrode under conditions that would destroy traditional materials. As an electrode, synthetic diamond can be used in waste water treatment of organic effluents and the production of strong oxidants.

In order to reduce the pollution caused by the food industry, Zaritzky developed techniques that apply natural coagulants to treat effluents, and created technologies that take advantage of the collaborative work of bacteria. Microorganisms build up "consortia" that consume pollutants and purify water. Thus, the use of these technologies in the food industry will reduce the pollution that it causes in the waters of rivers, streams and lagoons. In addition, Zaritzky found a solution to the problem of waste generated by the processing of prawns, crabs, shrimp and crabs in Patagonia.

Because the fathead minnow is fairly tolerant of harsh conditions, it can be found in bodies of water that may be uninhabitable to other fish, such as waste drainage sites. It has also been studied to investigate the effects of these waste materials on the aquatic life. Natural and synthetic oestrogens, such as oestradiol and oestrone, are present in sewage treatment works effluents. In male fathead minnows, exposure to these steroidal compounds leads to an increase in plasma vitellogenin levels exceeding that of even mature female fathead minnows.

Anodizing is one of the more environmentally friendly metal finishing processes. Except for organic (aka integral colour) anodizing, the by-products contain only small amounts of heavy metals, halogens, or volatile organic compounds. Integral color anodizing produces no VOCs, heavy metals, or halogens as all of the byproducts found in the effluent streams of other processes come from their dyes or plating materials. The most common anodizing effluents, aluminium hydroxide and aluminium sulfate, are recycled for the manufacturing of alum, baking powder, cosmetics, newsprint and fertilizer or used by industrial wastewater treatment systems.

According to the documentary Green Warriors Indonesia by Martin Boudot, some of the other toxins include sulphites, nonylphenol, phtalates, PCB 180, paranitrophenol, tributylphosphate. The documentary also mentions that the most dangerous pollution comes from the Indonesian textile industry (with many textile factories being part of Asosiasi Pertekstilan Indonesia). It is also mentioned that the textile factory effluents are only tested on a very select number of parameters. It was thus also proposed in the documentary that a revisal on the textile industry guidelines could include more parameters such as sulphites and heavy metals.

Electro-oxidation (EO), also known as anodic oxidation, is a technique used for wastewater treatment, mainly for industrial effluents, and is a type of advanced oxidation process (AOP). The most general layout comprises two electrodes, operating as anode and cathode, connected to a power source. When an energy input and sufficient supporting electrolyte are provided to the system, strong oxidizing species are formed, which interact with the contaminants and degrade them. The refractory compounds are thus converted into reaction intermediates and, ultimately, into water and CO2 by complete mineralization.

The economics of the international and local market of gasolines dictates the spread that a buyer need to pay for isobutane compared to standard commercial butane. For all these reasons alkylation margin is very volatile but in spite of its volalitility during the last 10 years it has been on a growing trend. In 2013 alkykation gross margin reached US$70/barrel of alkylate produced (value calculated accorded to the prices of alkylation feedstocks and effluents on the US Gulf Coast market). Gross margin however exclude variable and fixed operating costs and depreciation.

Since its early days, Sellafield has discharged low-level radioactive waste into the sea, using a flocculation process to remove radioactivity from liquid effluent before discharge. Metals dissolved in acidic effluents were made to produce a metal hydroxide flocculant precipitate following the addition of ammonium hydroxide. The suspension was then transferred to settling tanks where the precipitate would settle out, and the remaining clarified liquid, or supernate, would be discharged to the Irish Sea. As an improvement to that process, in 1994 the Enhanced Actinide Removal Plant (EARP) became operational.

Phytovolatilization involves the capture and subsequent transpiration of radionuclides into the atmosphere. It does not remove contaminants but releases them in volatile form (less harmful). Despite not having too many applications for radioactive waste, it is very useful for the treatment of tritium, because it exploits plants' ability to transpire enormous amounts of water. The treatment applied to tritium (shielded by air produces almost no external radiation exposure, but its incorporation in water presents a health hazard when absorbed into the body) uses polluted effluents to irrigate phreatophytes.

Environmental legislation in many countries, and the whole of the European Community area (see RoHS), has led to a change in formulation of both solders and fluxes. Water-soluble non-rosin-based fluxes have been increasingly used since the 1980s so that soldered boards can be cleaned with water or water- based cleaners. This eliminates hazardous solvents from the production environment, and from factory effluents. Those regulations have also reduced the use of lead based solders, and caused the melting temperatures of solders in use to increase by up to .

The Polyarc reactor is a scientific instrument for the measurement of organic molecules. The reactor is paired with a flame ionization detector (FID) in a gas chromatograph (GC) to improve the sensitivity of the FID and give a uniform detector response for all organic molecules (GC-Polyarc/FID). The reactor converts the carbon atoms of organic molecules in GC column effluents into methane before reaching the FID. The resulting detector response is uniform on a per carbon basis and allows the FID to have truly universal carbon sensitivity.

Discharge of effluent from these treatment plants and disposal of sludge on land is the primary route of environmental exposure to triclocarban. Research shows that triclocarban and triclosan have been detected in sewage effluents and sludge (biosolids) due to their incomplete removal during wastewater treatment. Due to their hydrophobic nature, significant amounts of them in wastewater streams partition into sludge, with concentrations at mg/kg levels. The volume of triclocarban reentering the environment in sewage sludge after initial successful capture from wastewater is s 127,000 ± 194,000 kg/yr.

In the recent days, a number of Tanneries, dyeing units, textile mills and bleaching units has been established in this zone of Erode Municipal Corporation. The higher industrialization rate in this zone has caused adverse effects to this canal. It faces a lot of hazards and the water turns purple often due to the mix of untreated effluents that gets released into them from the nearby tanneries, dyeing and bleaching units. The Government along with some other civic agencies has taken several measures to control pollution in this canal, by implement some biological and mechanical treatment methodologies with aid from Norway-based companies.

The spacecraft will land in the far northern region of Mars, above the Arctic Circle in the area that the Mars Odyssey spacecraft has found evidence for water. An arm on the lander will dig a trench a meter deep in the surface of Mars to look for water ice and other water related substances (minerals). These will be scooped up and analyzed in a series of small furnaces. The effluents from the furnaces will be analyzed by the UT Dallas mass spectrometer to determine the presence of water and the mineralogical composition of soil samples.

Induced gas flotation (IGF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin. The small bubbles adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device. Induced gas flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants and similar industrial facilities.
|
|
The wastewaters from large-scale industries such as oil refineries, petrochemical plants, chemical plants, and natural gas processing plants commonly contain gross amounts of oil and suspended solids. Those industries use a device known as an API oil-water separator which is designed to separate the oil and suspended solids from their wastewater effluents. The name is derived from the fact that such separators are designed according to standards published by the American Petroleum Institute (API). The API separator is a gravity separation device designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size.

After approximately 15 years of ignoring high court rulings, the government shut down more than 100 tanneries the weekend of 8 April 2017 in the neighborhood. The higher cost associated with the treatment of effluents than to untreated effluent discharging leads to illegal dumping to save on costs. For instance, in Croatia in 2001, proper pollution abatement cost US$70–100 per ton of raw hides processed against $43/t for irresponsible behavior. In November 2009, one of Uganda's main leather making companies was caught directly dumping waste water into a wetland adjacent to Lake Victoria.

The impact of the discharged waters on the quality of the Hron river water, fauna and flora is negligible. Emissions to the atmosphere and effluents to the hydrosphere are regularly measured and assessed in the 15-km area around the plant. There are 25 monitoring stations of the tele-dosimetry system, which continuously monitor the dose rate of gamma radiation, activity of aerosols and radioactive iodine in the air, soil, water and food chain (feed, milk, agricultural products). The volume of radioactive substances contained in liquid and gaseous discharges is considerably lower than the limits set out by authorities.

In 2009, SEPA was maintaining and operating a significant network of gauging stations and rain gauges to provide national flood warning and forecasting services for Scotland. SEPA holds over 30 years of hydrometric data for Scotland's rivers. These data are invaluable in characterising the long-term pressures on Scotland's environment, particularly in relation to the assessment and management of the consequences of climate change. SEPA's testing, analysis and interpretation of samples covers a wide range of environments throughout Scotland, including contaminated land, fresh and saline waters, soils and sediments, sewage and industrial effluents, leachates, fauna and biota, and landfill gases.

According to a traditional story, the Mexica wandered in the deserts of modern Mexico for 100 years before they came to the thick forests of the place now called the Valley of Mexico. Tenochtitlan was founded on an islet in the western part of the lake in the year 1325. Around it, the Aztecs created a large artificial island using a system similar to the creation of chinampas. To overcome the problems of drinking water, the Aztecs built a system of dams to separate the salty waters of the lake from the rain water of the effluents.

It has also been proven that at even sub- inhibitory concentrations (e.g., one-fourth of the MIC), several antibiotics are able to have an effect on gene expression (e.g., as shown for the modulation of expression of toxin-encoding genes in Staphylococcus aureus). For reference the MIC of erythromycin that is effective against 90 percent of lab grown Campylobacter bacteria, the most common food-borne pathogen in the United States, is 60 ng/mL. One study found that the average concentration of erythromycin, a commonly prescribed antibiotic, was 0.09 ng/mL in water treatment plant effluents,.

Section of the Canal near RA Puram with MRTS The canal was used to convey goods up and down the coast from Vijayawada to Madras (now Chennai). The cyclones of 1965/1966 and 1976 damaged the canal, and it is little used and no longer well maintained. Within the city of Chennai the canal is badly polluted from sewage and industrial effluents, and the silting up of the canal has left the water stagnant, creating an attractive habitat for malaria-spreading mosquitoes. The North Chennai Thermal Power Station (NCTP) discharges hot water and fly ash into the canal.

Many wetlands have either been lost or spoiled. Rivers and streams have been choked with tailings from the waste material dumped from the nickel mines. This has resulted in rise in bed levels of the rivers and consequent flooding affecting fertile agricultural lands. Many river delta areas have been affected creating changes in aquatic flora and fauna; the mining effluents are reported to have affected about 40 streams in their middle and lower reaches. Even estuaries and bays are reportedly affected by the “red clay and lateritic sub-soil,” which covers some of the mangrove forests.

The lower river should be tidal, but a sluice gate built at the same time as the docks keeps the water fresh. From the 1940s through to the 1970s, the bottom stretches of the Cadoxton were polluted by effluents from the many chemical plants nearby. However, due to environmental regulation the water quality is now improving and the river supports fish, including trout. On 19 April 2005, most of the river's trout were killed when dangerous pollutants leaked from a vehicle travelling to the Barry chemical plants, seeping into Bullcroft Brook and thus damaging the ecosystem.

The upper Nile receives its chief supplies from the mountainous region adjoining the Central African trough in the neighborhood of the equator. From there, streams pour eastward into Lake Victoria, the largest lake in Africa (covering over 26,000 square m.), and to the west and north into Lake Edward and Lake Albert. To the latter of these, the effluents of the other two lakes add their waters. Issuing from there, the Nile flows northward, and between the latitudes of 7 and 10 degrees north it traverses a vast marshy level, where its course is liable to being blocked by floating vegetation.

Wind flow, waves, and turbulence that move the boat in the sea add to this unawareness. UN law advocates a minimum penalty for this offense and release of boats, but the governments of India and Pakistan catch these fishers and keep them in prisons for a long time. Their release happens through the land boundary of India and Pakistan (Wagha border), so these fishers return to their home country without their boats. Pakistan built the LBOD canal between 1987 and 1997 to collect agricultural saline water and industrial effluents generated in the area around the main Indus river.

A woman using COCPs excretes from her urine and feces natural estrogens, estrone (E1) and estradiol (E2), and synthetic estrogen ethinylestradiol (EE2). These hormones can pass through water treatment plants and into rivers. Other forms of contraception, such as the contraceptive patch, use the same synthetic estrogen (EE2) that is found in COCPs, and can add to the hormonal concentration in the water when flushed down the toilet. This excretion is shown to play a role in causing endocrine disruption, which affects the sexual development and the reproduction, in wild fish populations in segments of streams contaminated by treated sewage effluents.

On 1991, a study noted that eutrophication in Laguna de Bay could be attributed to nutrients brought to the lake as a result of the tremendous deterioration of the Morong River and the San Pedro River. In the case of the Morong River, this increase was said to be a result of draining effluents from hog farms. A 1994 cleanup drive initiated by the Laguna Lake Development Authority in cooperation with the local communities and local government units of Antipolo, Morong, and Teresa removed some seven truckloads of garbage and cleared a portion of the river from water lilies blocking the waterway.

In 1967 the Army Scientific Advisory Panel sent John D. Baldeschwieler to Vietnam in order to conduct controlled experiments and determine the ability of the people sniffers to detect ammonia. The tests showed that the people sniffer responded randomly to ammonia indicators, making it a very subjective instrument. Despite this, the ability of the people sniffer to detect other effluents, such as smoke, helped it to remain a valuable tool during the Vietnam War. The Viet Cong (VC) and the North Vietnamese Army (NVA) were able to develop effective, low-tech countermeasures to the people sniffers.

Traffic congestion in Lagos, environmental pollution:water pollution, and air pollution; and noise pollution are major health issues. Water pollution The aquatic systems in Nigeria, no doubt, are reservoirs for toxic chemicals and dead-ends for different kinds of chemical compounds and their products. The activities of oil and gas industries as well as widespread discharge of effluents into water ways is an eyesore. Chemical substances such as polyaromatic hydrocarbons, per- and polyfluoroalkyl substances as well as heavy metals from point (see point pollution)and non-point (see nonpoint pollution) sources finds their way into oceans, rivers and streams and contaminates it.

Industrialisation caused the river and the Dearne and Dove Canal, to become grossly polluted in the early nineteenth century and fish populations died. The West Riding River Board tried to address the problems in 1896 with limited success and much of the river remained dead until the 1980s, when industrial effluents were removed before they were discharged and improvements were made to sewage treatment. Despite setbacks, fish populations had been partially reinstated by the early 1990s. Channel engineering was carried out at Denaby in the 1990s, to re-introduce bends, deep pools and shallow gravel riffles, to assist fish spawning.

The lands of the Rio Pomba basin are severely deforested, a process that began throughout the Zona da Mata during the coffee era and did not spare even the headwaters of the river. It is a factor that contributes to the degradation of the river, also affected by the release of industrial and domestic effluents. In 2003 a major spill of more than 1 billion gallons of toxic waste from one industry in Cataguases caused enormous environmental damage, and the effect was detected in the Paraiba do Sul River to its mouth in the Atlantic Ocean in the state of Rio de Janeiro.

Before the CWA was enacted, companies indiscriminately discharged their effluents into water bodies. One such water body was the Cuyahoga River located in north-east Ohio. The river was thrust into the national limelight in 1969 when it caught fire, although the river had been plagued by fires since 1936. Pollution of the river had become prevalent in the early 1800s as contaminants from municipal and industrial discharges, bank erosion, commercial/residential development, atmospheric deposition, hazardous waste disposal sites, urban storm water runoff, combined sewer overflows (CSOs) and wastewater treatment plant bypasses were discharged into the river.

Tritium has leaked from 48 of 65 nuclear sites in the US. In one case, leaking water contained of tritium per liter, which is 375 times the EPA limit for drinking water.Radioactive tritium leaks found at 48 US nuke sites. NBC News (21 June 2011). Retrieved on 16 October 2014. The US Nuclear Regulatory Commission states that in normal operation in 2003, 56 pressurized water reactors released of tritium (maximum: 2,080 Ci; minimum: 0.1 Ci; average: 725 Ci) and 24 boiling water reactors released (maximum: 174 Ci; minimum: 0 Ci; average: 27.7 Ci), in liquid effluents.

According to the Water Quality Index, 96% of Mexico's surface water bodies have different levels of pollution. OECD estimates the economic cost of water pollution in Mexico at US$6 billion per year. The problem is most serious in the Valle de Mexico region where 100% of the water bodies have different levels of contamination, 18% of which are highly polluted. Low water quality is due to untreated discharge of industrial effluents and municipal wastewater into rivers and lakes, solid waste deposits along river banks, uncontrolled seepage from unsanitary landfills, and non- point pollution mainly from agricultural production.

One day, Malar gets the news that her friend Kalpana (Darshana Rajendran), who is a social activist, has been raped with the blame put on her boyfriend Abdul Kader (Vikranth). Thilak, creative head Ashok (Five Star Krishna), and Malar manage to smuggle out Kalpana from the hospital and convince her to tell her story. Kalpana had been raped by Dheeran's goons in retribution for protesting against Dheeran's pesticide factory, which had ruined a once-prosperous village due to the effluents coming out of the factory, and the blame was put on Abdul instead. This confession is telecasted live, and Kalpana gains massive support from the public.

Teztan Biny is a vital part of the watershed that supports one of the largest and most productive salmon fisheries in North America. We have deep concerns that any toxic effluents that seep from the mine tailings and waste rock facilities at the proposed mine could negatively impact BC's already threatened Fraser salmon fishery. Chief Marilyn Baptiste, following in the long tradition of strong Tsilhqot'in leaders, has again taken the Tsilhqot’in claims to court by filing another case seeking a specific declaration of an Aboriginal right to fish in Teztan Biny. She is acting on behalf of our elders, our leaders and future generations.

Ecological cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material. One is Geopolymer cement. New manufacturing processes for producing ecological cement are being researched with the goal to reduce, or even eliminate, the production and release of damaging pollutants and greenhouse gasses, particularly CO2. Growing environmental concerns and the increasing cost of fuels of fossil origin have resulted in many countries in a sharp reduction of the resources needed to produce cement and effluents (dust and exhaust gases).

Disposal of the effluents produced by the brewery were also a major problem and pollution of the River Sheppey was a source of much discontent amongst land owners further down the valley from 1877 until the closure of the brewery in 1921. In 1890 it was reported that the beer brewed at the Anglo-Bavarian was sold throughout England and the Channel Islands by 250 agents. However the brewery’s main area of sales was export. Beginning in 1875, beer was transported to a bottler in London, from where it was shipped to Australia, New Zealand, India, South Africa, South America and the West Indies.

NOWPAP covers the marine and coastal zone ranging from 33°N to 52°N latitude, and from 121°E to 143°E longitude. Being one of the most densely populated parts of the world, where people are particularly dependent on the sea for their food and livelihood, the region is suffering from enormous pressures and demands on its marine environment. Thus people and ecosystems are under severe threat mainly from land-based activities and sources of pollution. Industrial effluents, untreated municipal sewage and run-off of agricultural pesticides and nutrients entering the NOWPAP marine environment cause eutrophication and harmful algal blooms (HAB, also known as red tides).

Climatically the region is characterized by having only two seasons during the year: a rainy season lasting from May to October and a dry season from November to April with a shorter dry season lasting 2 weeks near the end of July. Efforts at improving water storage during the rainy season aim to address inadequate supplies and meet water demands during the dry season. Water shortages are one of the main challenges facing Tegucigalpa and the areas making up the Choluteca river basin. Other significant challenges include poor water quality from untreated industrial effluents and sewage discharging into the river network, and severe risk of flooding from tropical storms and hurricanes.

Biological oxidizer capture module Micro-organisms are utilized in biological remediation to control industrial and commercial vapor effluents. When utilizing biological oxidation systems for the remediation emissions, the off gases or vapors are passed through a packed bed having a thin biological film at the surface. The micro-organisms are immobilized into the thin biological film, as the vapor passes over the film they become attached and are oxidized or stabilized. The biological film accomplishes the degradation process, as the biological sump water is reprocessed over the biomedia it creates additional biological growth and as the film increases so does the biological oxidizers efficiency.

Analytical procedures for rapid and accurate estimation of quality of water were developed and these are now widely in use. Water being an important resource for all life processes and for industry, specific technologies were developed for treatment of industrial wastewaters as well as domestic effluents. Recycling, therefore, has been a very significant area of R&D; at the Institute for water management, since wastewater after treatment can be used in agriculture. Between the mid-eighties and the late nineties, the Institute saw a phenomenal growth in its activities, swelling number of projects and a concomitant overall growth of in-house infrastructure facilities including analytical Instruments.

Forest Guardian's Page on the Rio Grande Silvery Minnow Even with the Rio Grande Silvery Minnows listing in 1994, its population has continued to drop at a great rate. The minnow now numbers way below its 1994 population, and is found in only 5 percent of its former habitat. Alterations of the Rio Grande not only includes the modification of the flow of water by dams and channels but also the unintentional polluting of the quality of the water. This pollution can be originated from many factors, the major ones being, effluents by the military and industrial companies as well as wastewater from cities and nearby towns.

Atlantic salmon became extirpated in the River Lagan, which enters the Irish Sea through the port of Belfast, between 1750 and 1800, coinciding with a period of major population growth, industrialisation and the construction of a navigable waterway based on the river. The latest record of a salmon population in the river dates from 1744. From 1950 to 1990, water quality in the river improved as a result of improved sewage treatment, the Lagan Navigation was abandoned and fell into disuse, and many industrial effluents were diverted to sewer. A fish survey in the early 1970s found no fish at all in the urban reach of river through Belfast.

By 1950 the Merrimack River was for the most part devoid of marine and riparian life, due to chemical effluents from the cloth and paper mills upstream in Haverhill, Lawrence, Lowell, Manchester, New Hampshire and Concord, New Hampshire as well as the dumping of raw sewage into the river from every community on its banks. Since then the industry has moved south, sewage is better treated and environmental laws have gone into effect and have been to some degree enforced in every community. Dams upstream prevent the return of migratory piscines but maritime life on the lower river has improved to the point of supporting a new population of eagles.

Many studies have therefore been focused to determining if the concentrations of these pharmaceuticals exist at or above the accepted daily intake (ADI) at which the designed biological outcomes can occur. In addition to the growing concerns about human health risks from pharmaceutical drugs via environmental exposures, many researchers have speculated about the potential for inducing an antibiotic resistance. One study found 10 different antibiotics in sewage treatment effluents, surface water, and sediments. Some microbiologists believe that if antibiotic concentrations are higher than the minimum inhibitory concentrations (MICs) of a species of pathogenic bacteria, a selective pressure would be exerted and, as a result, antibiotic resistance would be selectively promoted.

A view of the Tâmega River flowing on the south margin of Santo Isidoro The local areas name, in homage to Saint Isidore of Seville, provides an understanding of the regions link to religious activities. In fact, the name provides an indication of the age, since the parish seat occupies the summit of a large mountaintop, with a slope that followed the Tâmega and its effluents. Lying on the bank of the Tâmega, also known as the Riba Tâmega, the parish occupies the flanks of the hills of Santa Cruz, delimited by Toutosa, Sobretâmega, Vila Caíz (Amarante) and the river. It is from the municipal seat.

In Chile, the Ministry of Publics Works developed the standard, the decrete number 609,Chilean Ministry of Public Works, NORMA DE EMISION PARA LA REGULACION DE CONTAMINANTES ASOCIADOS A LAS DESCARGAS DE RESIDUOS INDUSTRIALES LIQUIDOS A SISTEMAS DE ALCANTARILLADO,1998 approved on May 7, 1998. This norm was created with the aim to control the effluents discharged into the sewer system. This norm establishes the maximum discharge concentration in sewer systems and also the different parameters that will be monitored, depending on the economic activity developed by each industry. It also establishes the methods that must be used for taking samples of each parameter.

The Pequabuck River is a river, approximately 19 miles (30.6 km) in length, which rises in Litchfield County, Connecticut, and courses through neighboring Hartford County before emptying into the Farmington River in Farmington. The river has played a crucial role in the development of Plainville, Connecticut, in particular. The river's lower drainage basin consists of industrial and urban areas, and effluents from these areas pollute the river's waters. The Pequabuck drove a water wheel that provided 8 horsepower to the Upper Lock Shop in Plymouth, Connecticut, a facility which would eventually become the Lewis Lock Company in 1851 and, finally, the once-renowned Eagle Lock Company.

The valley owes its fertility to two rivers, the Naryn and the Kara Darya, which unite in the valley, near Namangan, to form the Syr Darya. Numerous other tributaries of these rivers exist in the valley including the Sokh River. The streams, and their numerous mountain effluents, not only supply water for irrigation, but also bring down vast quantities of sand, which is deposited alongside their courses, more especially alongside the Syr Darya where it cuts its way through the Khujand- Ajar ridge and forms the valley. This expanse of quicksand, covering an area of , under the influence of south-west winds, encroaches upon the agricultural districts.

The Government of Argentina (GoA) with World Bank assistance has aimed to reduce industrial wastewater discharge (organic as well as toxic effluents) that directly enter the MR River. Over the next 15–20 years these efforts will contribute to the environmental recovery of the river. They will focus on the 50 main industrial polluters that contribute ~95% of the total industrial organic load (approximately 70 percent of the total organic load) discharged to the MR River and a further 170 industries with the highest toxic load currently discharged into the MR River. A combination of technical assistance to improve monitoring, control, and enforcement by the MR Basin Authority will be instituted.

As the initial portion of the canal runs through the highly industrialized and urbanized areas of Erode Municipal Corporation, the discharge of untreated effluents from the textile dyeing units and leather tanneries introduce major pollutants. To prevent mixing of sewage into the canal, the Government of Tamil Nadu have built concrete walls on the sides and a baby canal of has been constructed alongside the main canal to carry the sewage. The entire stretch of first 30 km of the canal running through Erode Municipal Corporation is proposed to be provided with concrete lining and baby canal in phased manner. Also, navigable roads were developed along the banks throughout this stretch.

Both total and per capita water usage is very high in comparison to other Central American countries but when measured against available freshwater sources, Costa Rica uses only 5% of its available supply. Urbanization is increasing and as it does, demand for water is expected to rise exponentially in the coming decades. There exists ample water but the threat of widespread contamination to the aquifers is legitimate as untreated wastewater, stormwater, and industrial effluents infiltrate subterranean supplies. Additionally, the government and water management institutions are facing a water conveyance infrastructure that is in decline; therefore, non-revenue water losses within the system are increasing.

Water pollution from industrial effluents is a considerable challenge and the risk of continued contamination is very likely. The Government of Argentina (GoA) has a particular focus on the Matanza- Riachuelo River Basin in Buenos Aires where at least 50 industries are discharging ~95% of the total load of contaminants into the Parana river. Pollution and overuse of the aquifer in Mendoza have become a problem where agriculture and industrial runoff and mismanagement of irrigation water has deteriorated the first levels of the aquifer. This has led to over pumping and exploitation of deeper wells that reach the second and third layers of water.

The Mula-Mutha is a river in India, formed by the confluence of the Mula and Mutha rivers in the city of Pune, which later meets the Bhima River, which itself later meets the Krishna River and finally emptying to the Bay of Bengal. The river flows through the village of Kavadi in the Solapur district, witnesses many migratory birds. However, increase in pollution in the recent years has resulted in a reduction in the number of birds. Pollution from effluents released into the river at Pune has been found to cause high levels of pollution in the Bhima River, the reservoir of Ujani dam and Krishna River, too, resulting in many water-borne ailments.

However, the rapid expansion of textile industries in Tiruppur led to installation of many dyeing units and soon, polluted effluents from the textile city of Tiruppur converted the once fertile Noyyal river into a virtual drain. The polluted river and vanishing tanks had dealt a big, still unrecoverable blow to agriculture, dairy farming, rice mills and paddy-hulling in these areas. Consequently, the young and old of this land are now forced to seek employment opportunities outside this once scenic spot. Apart from water pollution, scarcity of water and steep rise in labor costs in an unorganized labor sector has resulted in agriculture taking a back seat and the traditional hereditary farms called "Thottams" are fast vanishing.

Tietê River, with the Marginal Tietê The Tietê River and its tributary, the Pinheiros River, were once important sources of fresh water and leisure for São Paulo. However, heavy industrial effluents and wastewater discharges in the later 20th century caused the rivers to become heavily polluted. A substantial clean-up program for both rivers is underway, financed through a partnership between local government and international development banks such as the Japan Bank for International Cooperation. Neither river is navigable in the stretch that flows through the city, although water transportation becomes increasingly important on the Tietê river further downstream (near river Paraná), as the river is part of the River Plate basin.

Some of the pollutants that laccases have been used to treat include dye-containing effluents from the textile industry, wastewater pollutants (chlorophenols, PAHs, etc.), and sulfur-containing compounds from coal processing. Exocytic vesicles move along actin microfilaments toward the fungal hyphal tip where they release their contents including exoenzymes Bacteria are also a viable source of exoenzymes capable to facilitating the bioremediation of the environment. There are many examples of the use of bacteria for this purpose and their exoenzymes encompass many different classes of bacterial enzymes. Of particular interest in this field are bacterial hydrolases as they have an intrinsic low substrate specificity and can be used for numerous pollutants including solid wastes.

Almost all of these industries discharge untreated effluents into the drainage system or directly into the MR River. In addition to high levels of organic pollution, these discharges contribute toxic contaminants such as heavy metals from petrochemical industries, tanneries, and meat processing facilities. More specifically, the Riacheuleo has levels of Lead, Zinc and Chrome 50 times higher than the legal limit in Argentina; 25% is from industrial sewage and waste, while the remaining 75% originates from domestic sources. The sudden onset of environmental and social degradation of the MR basin has resulted from limited investment in public infrastructure, poor environmental management, lack of adequate urban and industrial planning, and limited public infrastructure investment.

All four of the original VVER-440/230 reactors have since been shut down, with only the two newer VVER-1000 units still in operation. Because cleanup has been economically problematic in the post-communist era, in the mid-2000s Bulgaria still had grave environmental crises. Among them were air pollution from industrial emissions; the inability to filter effluents into rivers, leading to concentrations of untreated sewage, heavy metals, and detergents; severely depleted natural forest cover; forest damage from air pollution and resulting acid rain; and soil contamination by heavy metals resulting from improper industrial waste disposal. In the 1990s and early 2000s, a rapid increase in motor vehicles using leaded fuel exacerbated urban air pollution.

A poison which enters the food chain—whether of industrial, agricultural, or natural origin—might not be immediately toxic to the first organism that ingests the toxin, but can become further concentrated in predatory organisms further up the food chain, particularly carnivores and omnivores, especially concerning fat soluble poisons which tend to become stored in biological tissue rather than excreted in urine or other water-based effluents. Apart from food, many poisons readily enter the body through the skin and lungs. Hydrofluoric acid is a notorious contact poison, in addition to its corrosive damage. Naturally occurring sour gas is a notorious, fast-acting atmospheric poison (as released by volcanic activity or drilling rigs).

Orange Coast College in Costa Mesa, California, has begun a program to use cups made with this technology to capture and sell the fibers to fund scholarships for their students.OCC will use recyclable cups to help fund new scholarship In 2017, the Finnish board manufacturer Kotkamills launched a new kind of cup (food service) board which uses no wax or plastic for waterproofing, and thus can be recycled as part of the normal paper and board waste stream, biodegraded, or even composted in small quantities. The manufacture of paper usually requires inorganic chemicals and creates water effluents. Paper cups may consume more non-renewable resources than cups made of polystyrene foam (whose only significant effluent is pentane).

Yoldia Sea is a name given by geologists to a variable brackish-water stage in the Baltic Sea basin that prevailed after the Baltic ice lake was drained to sea level during the Weichsel glaciation. Dates for the Yoldia sea are obtained mainly by radiocarbon dating material from ancient sediments and shore lines and from clay-varve chronology. They tend to vary by as much as a thousand years, but a good estimate is 10,300 – 9500 radiocarbon years BP, equivalent to ca 11,700-10,700 calendar years BP. The sea ended gradually when isostatic rise of Scandinavia closed or nearly closed its effluents, altering the balance between saline and fresh water. The Yoldia Sea became Ancylus Lake.

The line was reinforced with new pillboxes in 1940 as the fortifications were outdated. The line was located at the extreme eastern edge of the area lying below sea level. This allowed the ground before the fortifications to be easily inundated with a few feet of water, too shallow for boats, but deep enough to turn the soil into an impassable quagmire. The area west of the New Hollandic Water Line was called Fortress Holland (Dutch: Vesting Holland; German: Festung Holland), the eastern flank of which was also covered by Lake IJssel and the southern flank protected by the lower course of three broad parallel rivers: two effluents of the Rhine, and the Meuse (or Maas).

The direct discharge of raw sewage into the waterbodies has caused eutrophication in both reservoirs as well as the Baixo Cotia, Biritiba and Ribeirão dos Cristais Rivers. In addition, defects in the wastewater treatment system have caused wastewater to overflow into the tributaries of the Guarapiranga reservoir. Defects in infrastructure for collecting and transporting sewage to the wastewater treatment plants also cause problems. The dumping of industrial effluents and pesticides from agriculture has resulted in additional pollution.World Bank:Integrated Water Management in Metropolitan Sao Paulo - Programa Mananciais, accessed on October 10, 2011 While the concentration of industry contributes to the water pollution problems in the MRSP, these are also a direct consequence of urbanization without the adequate infrastructure.

When appropriate oxidizing agents are dissolved into the solution, the electro- oxidation process not only leads to organics oxidation at the electrode surface, but it also promotes the formation of other oxidant species within the solution. Such oxidizing chemicals are not bound to the anode surface and can extend the oxidation process to the entire bulk of the system. Chlorides are the most widespread species for the mediated oxidation. This is due to the chlorides being very common in most wastewater effluents and being easily converted into hypochlorite, according to global reaction: Cl- + H2O -> ClO- + 2H+ + 2e- Although hypochlorite is the main product, chlorine and hypochlorous acid are also formed as reactions intermediate.

The inhabitants of the castle complained of the smell of the slope, so the conduits were extended to the Brusnice stream. One leads from Hradcany Square and the other, known as the castle passage, from the second castle courtyard to the bottom of the Deer Moat. Paisley Abbey At Paisley Abbey in Scotland, few of the original monastic buildings survived into the 20th century, so landscaping of the area around the church in 1990 provided an ideal opportunity to investigate the positions of those now "lost" channels. The main drain, which would have brought fresh water into the complex and taken away the effluents, would have acted as the spinal column of the buildings.

Identifying the above major issues as causes for the deterioration of the lake, a multidisciplinary team of experts have prepared a Detailed Project Report (DPR), which has the objective of achieving environment and sustainability, ecological improvement with minimum interventions and displacement and balancing the conflicts of interest. This plan is now under implementation with the financial assistance of the Government of India. The serious nature of the environmental problems the lake has been experienced has been widely publicised and has been brought to the attention of the Supreme Court of India. Public Interest Litigations (PILs) have been filed in court demonstrating the environmental dangers posed to the lake by sewage, wastes and effluents.

The major drainages tributary to the Occoquan Reservoir can be divided into two principal sub-basins: Bull Run and Occoquan Creek. Despite being a major fresh water source, Occoquan Reservoir is listed on Virginia's Dirty Water List, with recorded high levels of phosphorus, turbidity, low dissolved oxygen, the presence of copper sulfate and the growing presence of pharmaceuticals, largely due to human land uses, population pressure and poor management. In 1968, the Virginia State Water Control Board (SWCB) commissioned a study of the Occoquan Reservoir and its tributary streams to draw up a plan of sustainable management for the reservoir. A 1970 analysis stated that the reservoir was "highly eutrophic...", and further, that "the sewage plant effluents are mainly responsible for the advanced stage of eutrophication occurring...".

Flame ionization detectors cannot detect inorganic substances and some highly oxygenated or functionalized species like infrared and laser technology can. In some systems, CO and CO2 can be detected in the FID using a methanizer, which is a bed of Ni catalyst that reduces CO and CO2 to methane, which can be in turn detected by the FID. The methanizer is limited by its inability to reduce compounds other than CO and CO2 and its tendency to be poisoned by a number of chemicals commonly found in gas chromatography effluents. Another important disadvantage is that the FID flame oxidizes all oxidizable compounds that pass through it; all hydrocarbons and oxygenates are oxidized to carbon dioxide and water and other heteroatoms are oxidized according to thermodynamics.

Interested, Long John Silver agrees and manages to plant several of his men among the crew of Captain Edward Hastings' ship Neptune before joining the crew himself, together with Dr. Livesey. After several weeks of hard work under Captain Hastings, the pirates lead a successful mutiny which places Silver into the captain's position. However, as the map to Guyanapac was lost together with Captain Hastings in the mutiny, the crew has to rely on Mox's guidance across the meanders of the Amazonas river and its numerous effluents. Not even yet arrived in Guyanacapac, the adventure takes a turn for the worse when the Neptune suddenly disappears shortly after finding what is left of the Nimrod, Lord Byron Hastings' ship, amid increasingly mysterious circumstances.

Utilization of halogen containing materials in processes such as water treatment, bleaching, or even general synthesis to create the final product, generates a number of organic halides. These organic halides are released in wastewater from the oil, chemical, and paper industries, and find their way to the consumer and eventually to a landfill or oceanic dumps. Within the soil, the halo compounds resist degradation and often react with metal ions, resulting in non-degradable metal complexes, increasing soil toxicity and accumulating in the food chain of aquatic organisms. Up to 2000 ppm of these bio- accumulative organic chlorides were detected in fat of fish from the waters where bleaching effluents were disposed by paper mills, where a 2% water concentration is considered toxic for the fish.

In response to the internationally recognized environmental crisis of the rapid desiccation of the Aral Sea, the five states sharing the Aral Sea Basin (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan) are developing a strategy to end the crisis. The World Bank and agencies of the United Nations (UN) have developed an Aral Sea Program, the first stage of which is funded by the five countries and external donors. That stage has seven areas of focus, one of which—land and water management in the upper watersheds—is of primary concern to Kyrgyzstan. Among the conditions detrimental to the Aral Sea's environment are erosion from deforestation and overgrazing, contamination from poorly managed irrigation systems, and uncontrolled waste from mining and municipal effluents.

Stream flowing wastewater from cities and industries, and wastewater from sawmills and quarries originating from Palestinian cities, residential, and quarries built along it. In the Beer Sheva Valley sewage is a significant environmental hazard, because thousands of people live close to the river bed. The main source of pollution is the sewage of Hebron and Kiryat Arba, estimated at 15,000 cubic meters per day, which also pollutes the Besor Nature Reserve, which changes the nature of the stream from a failed stream that flows high- quality floodwater into a stream with a permanent flow of polluted sewage . Sewage flows throughout the year that pollute the stream and groundwater in the stream, and there are additions of urban and industrial effluents.

The 19th-century industrial concentrations in the above-named urban areas resulted in the Tame being a much polluted waterway. As well as industrial pollution from the dyes and bleaches used in textile mills, effluent from specialised paper-making [cigarette papers], engineering effluents, including base metal washings from battery manufacture, phenols from the huge coal-gas plant in Denton, rain-wash from roads and abandoned coal spoil heaps there was also the sewage effluent from the surrounding population. Up to two-thirds of the river's flow at its confluence with the Goyt had passed through a sewage works. The anti-pollution efforts of the last thirty years of the 20th century have resulted in the positive fauna distributions listed below.

The gradual decrease in Peru's water quality is due to the release of untreated effluents from mining, industries, municipalities and polluted runoff from agriculture. Of the 53 rivers in the coastal area, 16 are polluted by lead, manganese and iron threatening irrigation and potable water supplies. In particular, the Ministry of Agriculture considers "alarming" the quality of seven rivers: the Mantaro and Tambo rivers in the Central Andes that drain towards the Amazonas; the small Moche River near the northern coastal city Trujillo and the Santa near the northern coastal city Chimbote; the Chillon and Rimac rivers near Lima; and the Chili River near Arequipa which is well known for its rafting. In the Mantaro basin alone 18 mining facilities discharge polluted water into the river.

A documentary called En Peyar Palar produced by Social Action Movement and Water Rights Protection Group, Chengalpattu and released on 30 June 2008 chronicles the plight of the river from its origin in Karnataka till it joins Bay of Bengal. The 85-minute documentary delves into how activities such as sand quarrying and discharge of industrial effluents are sucking the life out of one of Tamil Nadu's prime sources of drinking water. It was directed by R.R. Srinivasan.A documentary charts the plight of Palar This river is so important for irrigation in the north and south Arcot districts of Tamil Nadu, but it flows a meager distance of in Andhra Pradesh, where the Palar river had been seen dry for almost 20 years.

In addressing many of this challenges, the city of Monterrey has become a model for sound and effective Integrated urban water management. The challenges that Monterrey has confronted pertain to scarcity of surface water resources, poor water quality due to untreated industrial effluents, political cycles and term-limits which can limit long- term vision, and water disputes between urban and agricultural users. Monterrey has good groundwater "well-fields" that supply about 40% of the water demand for the city and generally are not over-exploited because of good connections to high-yield aquifer systems in the central parts of the "Curvatura de Monterrey". These wells are managed as storage reserves that can be used in time of drought, which is quite common in this region of Mexico.

In response to the contamination of the San Juan River, the government of Nuevo León initiated a sanitation program in 1994 entitled Plan Monterrey IV, which included the construction of three large wastewater treatment plants and the discharge of municipal effluents and treated water to other Rio San Juan tributaries. The public perception has remained, however, that the San Juan River is still a polluted river. Disputes over water between agriculture and municipal needs have been mitigated to some degree as the Monterrey water utility, SADM, now returns treated effluent back to the farming districts. This solution seems to be working for both sectors; however, the program and strategy will have to be re-evaluated as water resources become more scarce.

Untreated sewage from the towns of Baalbek, Houch el Rafqa, Qaa er Rim, Zahle, Chtoura, Qabb Elias, Bar Elias, Joub Jannine and Qaraoun flow into the Litani River or its tributaries, apart from industrial effluents many factories related to manufacture of sugar, paper, lead, limestone crushers, agro-industries and also from poultry farms, tanneries and slaughterhouses. The pollution is noted by the high recorded values of BOD5 (79 mg/L) and nitrates (1.7 mg/L) in the Litani River. The vegetation in the periphery of the lake consists of woodland, orchards, and low-growing scrub. During water- level variations in the lake, as the stored water is utilised for various beneficial uses, no submerged or emergent vegetation have been noticed.

Variation in the RVP specification for gasoline between countries and between seasons dramatically impacts the amount of butane streams that can be blended directly into gasoline. The transportation of specific types of LPG streams can be expensive so local disparities in economic conditions are often not fully mitigated by cross market movements of alkylation feedstocks. The common source of the C3 alkenes for the alkylation is made available from the gas recovery unit processing the effluents of the Fluid catalytic cracking Unit. Isobutane is partly made available from the Catalytic reforming and from the Atmospheric distillation, although the proportion of the isobutane produced in a refinery is rarely sufficient to run the unit at full capacity and additional isobutane needs therefore to be brought to the refinery.

It aimed to do so by improving the operational efficiency and financial sustainability of the two Provincial Water and Wastewater Companies (WWCs). The project financed the extension and improvement of water distribution systems including metering, sanitary sewers, and a wastewater treatment plant (in Sari) which was not completed at project closure. The project did not succeed in improving the financial situation of the two water and wastewater companies, since tariff increases were delayed. The Ahvaz and Shiraz Water Supply and Sanitation Project, supported by a US$279m loan approved in 2004 and closed in 2009, aimed to improve access to satisfactory water supply and significantly increasing coverage of sanitation services; and improve environmental, hygiene and health conditions, as well as promoting reuse of treated effluents.

In 1945, Palin became the first chief chemist and bacteriologist to the Newcastle and Gateshead Water Co. and established a scientific department with laboratories for research and development. It became evident to Dr. Palin that, outside the laboratory, there was a need for a simple, reliable system of routine water testing suitable for use by works operators, upon whom the safety of the public water supply depends. He developed a system based upon the use of standardized test tablets, applicable to the treatment control of potable water, swimming pools, sewages and effluents, boiler waters and industrial waters of all types. Wilkinson & Simpson, now Palintest Ltd (part of Halma plc), contributed to the development of the tablet tests, and in 1960 were granted an exclusive licence to manufacture and market the Palintest System of water testing.

It consists in the oxidation of organic matter using hydroxyl radicals generated from hydrogen peroxide by ferrous ions. The OHP reaction is carried out in the acidic medium and mild condition of temperature (100-150 degrees Celsius) and pressure (2-4 bar) in a safe and efficient way, using optimized catalyst and hydrogen peroxide formulations. Combination of mild temperatures (higher than conventional Fenton's reaction but still lower than other oxidative techniques) together permits to cover the gap between wastewater technologies to treat the effluents with moderate to high refractory organic matter content and low biodegradability. There are some types of wastewater where conventional treatment methods (biological, physical-chemical) are not efficient enough and on the other hand severe conditions oxidative methods (incineration, high pressure/temperature oxidation systems) are not economically attractive.

The Agency has a duty to maintain and improve the quality of surface waters and ground-waters and, as part of the duty, it monitors the quality of rivers, lakes, the sea and groundwater on a regular basis. Much of this information is required by law under the provisions of a number of European Directives to be reported both to Parliament and to Europe and to be made public. Some of these duties have been in force through predecessor agencies and as a consequence the Agency maintains some long term data sets which in some cases such as the Harmonised monitoring scheme exceed 30 years of consistent data collection. Monitoring is also carried out of many discharges to the aquatic environment including sewage effluents and trade and agricultural discharges.

According to one study, sucralose is digestible by a number of microorganisms and is broken down once released into the environment. However, measurements by the Swedish Environmental Research Institute have shown sewage treatment has little effect on sucralose, which is present in wastewater effluents at levels of several μg/l (ppb).Measurements of Sucralose in the Swedish Screening Program 2007, Part I; Sucralose in surface waters and STP samples No ecotoxicological effects are known at such levels, but the Swedish Environmental Protection Agency warns a continuous increase in levels may occur if the compound is only slowly degraded in nature. When heated to very high temperatures (over 350 °C or 662 °F) in metal containers, sucralose can produce polychlorinated dibenzo-p-dioxins and other persistent organic pollutants in the resulting smoke.

Nutrients and carbon are removed from farmland as food is harvested, processed and eaten and the resulting waste is discharged into rivers and coastal waters downstream from population centres and usually not returned to farmland. Rivers and oceans become increasingly contaminated by sewage, toxic effluents and mineral run-offs. This deleterious relationship in which cities are unable to interact in a mutually beneficial way with the ecosystems on which they depend is putting at risk the long-term viability of urbanization. Regenerative urban development is based on the understanding that if urban areas are to continue to offer individuals around the world the prospect of an improved quality of life and ability to realise their potential and aspirations, they must embrace their role in ensuring that the earth’s life support systems remain healthy and sound.

SPMDs, or semipermeable membrane devices, are a passive sampling device used to monitor trace levels of organic compounds with a log Kow > 3. SPMDs are an effective way of monitoring the concentrations of chemicals from anthropogenic runoff and pollution in the marine environment because of their ability to detect minuscule levels of chemical. The data collected from a passive sampler is important for examining the amount of chemical in the environment and can therefore be used to formulate other scientific research about the effects of those chemicals on the organisms as well as the environment. Examples of commonly measured chemicals using SPMDs include: PAHs (Polycyclic aromatic hydrocarbons), PCBs (polychlorinated biphenyls), PBDEs (polybrominated diphenyl ethers), dioxins and furans as well as hydrophobic waste-water effluents like fragrances, triclosan and phthalates.

AIR-INK is a proprietary brand of ink and composites products made by condensing carbon-based gaseous effluents generated by air pollution due to incomplete combustion of fossil fuels. Founded by Graviky Labs, a spin-off group of MIT Media Lab, AIR-INK produces its materials through a step-by-step process which primarily involves capturing of emissions, separation of carbon from the emissions, and then mixing of this carbon with different types of oils and solutions to achieve advanced material properties. It uses a patented device and technique called 'KAALINK' to carry out the filtration of soot, which contains carbon and other polluting agents like heavy metals and Polycyclic aromatic hydrocarbon. AIR-INK is marketed as a solution to air pollution and its negative effects on human life, by allowing the print industry to offset its carbon.

In a 2004 study, the El Salvador Ministry of Environment found that the waste is coming from 54 industrial plants, 55 coffee processing plants, seven sugar mills, and 29 sewer systems discharging directly into the reservoir. Cerrón Grande dam was built in 1974 to drive El Salvador's largest hydroelectric project, and the 135 km2 reservoir collects some 3,800 tones of excrement each year from the sewage pipes, as well as factory effluents consisting of heavy metals such as chromium and lead. The sedimentation volumes in the Cerron Grande Reservoir are dangerously high also and estimated to be as high as 7 million m3 per year which gravely impacts the health of the reservoir. Many shallow aquifers are becoming contaminated from the severe surface pollution, and this is critically challenging as deeper wells are more relied upon to provide potable water.

Natural draft wet cooling towers at many nuclear power plants and large fossil fuel-fired power plants use large hyperboloid chimney-like structures (as seen in the image at the right) that release the waste heat to the ambient atmosphere by the evaporation of water. However, the mechanical induced-draft or forced-draft wet cooling towers in many large thermal power plants, nuclear power plants, fossil-fired power plants, petroleum refineries, petrochemical plants, geothermal, biomass and waste-to-energy plants use fans to provide air movement upward through down coming water, and are not hyperboloid chimney- like structures. The induced or forced-draft cooling towers are typically rectangular, box-like structures filled with a material that enhances the mixing of the upflowing air and the down flowing water. (Includes cooling tower material balance for evaporation emissions and blowdown effluents.

A petroleum refinery was established recently in 2001 at Numaligarh upstream from the park on the Dhansiri river has potential danger present of pollution of the park's land and water bodies from the effluents/wastes from the refinery. Similarly a number of tea gardens present close to the park also remain a source of disturbance and pollution of the land and water bodies in the park. Increasing tourist in the park also proves to be a source of disturbance to the wild animals. There is a lack of trained staffs in the park and as of 2005, 127 of the 592 sanctioned posts lay vacant Moreover, since the area of the park has almost doubled (through additions) the staff strength would need to be further increased to undertake anti-poaching measures, conservation of wildlife and other allied activities.

While the responsibility for the provision of water supply and sanitation services in Canada lies with municipalities, the provincial governments and the federal government also have important responsibilities related to the setting of standards, research, economic regulation and water resources management. As all levels of government hold key policy and regulatory levers which apply to water and sanitation, a central challenge is to ensure that these levers are developed and used collaboratively. The Canadian Council of Ministers of the Environment - which consists of the 14 environment ministers from the federal, provincial and territorial governments - plays an important role in the development of national strategies, norms and guidelines for water supply and sanitation. The need and the difficulty to collaborate between different levels of government is apparent in the discussion of a proposed national municipal wastewater effluents strategy.

Lake levels in general follow the rainfall pattern in the catchment area. Lake Naivasha, once described as the Jewel in the Crown of all the East African lakes, has in recent decades been subjected to a series of devastating human pressures, not least the establishment of a vast horticulture and agriculture industry along its shorelines, but also the ever- increasing inflows of nutrients from siltation, sewage and other effluents emanating from a lakeside human population now approaching a million people. In 1981, the first geothermal plant for Lake Naivasha was commissioned and by 1985, a total of 45 MW of electricity was being generated in the area. The water level for Lake Naivasha reached a low of 0.6 m depth in 1945, but the water level rose again, with minor drops, to reach a maximum depth of nearly 6 m in 1968.

Furthermore, the capital city lies within a geographic depression amongst the surrounding mountain range making the city prone to flooding and landslides with both occurring in 1998 when Hurricane Mitch passed through Tegucigalpa killing 180 people and leaving many more displaced. Other critical IUWM issues include: inadequate water quality and quantity levels, deteriorating watersheds, rivers, and storage reservoirs, inefficient water use, rapid and poorly planned urbanization, intensive competition between industrial and domestic water users as well as irrigation demands, and industrial and domestic effluents discharging into the rivers, tributaries, and reservoirs without treatment. Overcoming these challenges has been difficult for SANAA (Servicio Autonomo Nacional de Acueductos y Alcantarillados), the state-run water and sewerage utility in Tegucigalpa. SANAA's funding and roles are becoming uncertain as Honduras continues to decentralize SANAA's functions and transfer SANAA assets to municipalities.

In South Africa, the town Garden Route, George faced water shortages and had decided on an IPR strategy (2009/2010), where final effluents from its Outeniqua WWTP are treated to a very high quality through UF and disinfection prior to being returned to the main storage facility, the Garden Route Dam, where they are combined with current raw water supplies. This initiative augments the existing supply by 10,000 m3 per day, approximately one third of the drinking water demand. The process configuration includes the following treatment processes: drum screen, UF, and chlorine disinfection. Provision has been made for powdered activated carbon (PAC) addition at George WTW, if required as an additional operational barrier. In Beaufort West, South Africa’s a direct wastewater reclamation plant (WRP) for the production of drinking water was constructed in the end of 2010, as a result of acute water scarcity (production of 2,300 m3 per day).

The river receives 800 million liters of largely untreated sewage and additional 44 million liters of industrial effluents each day. Only 35 percent of the sewage released into the river are believed to be treated. To address river pollution, measures have been taken by the Ministry of Environment and Forests (MoEF) in 12 towns of Haryana, 8 towns of Uttar Pradesh, and Delhi, under the Yamuna Action Plan (YAP) which has been implemented since 1993 by the MoEF's National River Conservation Directorate (NRCD). The Japan Bank for International Cooperation is participating in the YAP in 15 of the towns (excluding 6 towns of Haryana included later on the direction of the Supreme Court of India) with soft loan assistance of 17.773 billion Japanese yen (equivalent to about 700 crore [7 billion rupees]) while the government of India is providing the funds for the remaining 6 towns.

The Act was an attempt to improve the provision of sewerage services in Scotland, by requiring local authorities to provide a network of sewers and treatment works or other facilities to deal with the contents of those sewers. Local authorities were further required to ensure that the sewer network was accessible to owners of premises, enabling them to connect to the network "at a reasonable cost". However, this concept was also applied to the local authority, who did not have to do anything that was not practicable at a reasonable cost. In the event that agreement could not be reached as to what was reasonable cost, the matter could be referred to the Secretary of State, and his decision would be binding. The Act was divided into three parts, with part I covering general provisions as to sewerage in sections 1 to 23, part 2 covering trade effluents in sections 24 to 38, and part 3 covering miscellaneous and general provision in sections 39 to 61.

The team also found dead birds after they consumed the water mixed with the effluent and also reported that the industry's process of cooling the effluents can cause health hazards to the staff and residents in the local region. In another instance, the NEERI reported water samples from dugwells and borewells around the spot were found to be non-drinkable due to its high chemical content. During 1998, the industry was operating at 10% capacity, compared to that of 2018. In a 2005 environmental audit by NEERI, the samples from a village 2-km northwest of the factory had levels of cadmium, copper, lead, chromium, and arsenic 2 to 9 times higher than allowed levels. Soil Samples were also analyzed in areas surrounding the plant during the study and arsenic levels ranged from 133 mg/kg to 287 mg/kg, where soils containing more than 50 mg/kg of arsenic are supposed to treated as a 'hazardous wastes' under the Indian Law.

The law is now known as the Clean Water Act of 1972 On June 28, 1966, the State of Maine's Commissioner of Sea and Shore Fisheries, Ronald W. Green, ordered closure of the shellfish beds in the waters of Searsport and Stockton Springs, in upper Penobscot Bay, "due to the polluted condition of the water." The US Department of the Interior's Water Pollution Control Administration and the US Public Health Service then conducted a joint investigation of the lower Penobscot River and upper Penobscot Bay "to determine the sources of this pollution, the direction of travel of this pollution and the degree of economic injury involved." In February 1967, the Water Pollution Control Administration (WPCA) published its findings as "Report on Pollution - Navigable Waters of the Penobscot River and Upper Penobscot Bay". The investigation found the sewage from eleven towns,and effluents of thirteen businesses and one university facility were the chief sources of the pollution.

A 2004 survey by the Bombay Natural History Society (BNHS) had found the 10 km Mahul creek and its environs along the Arabian sea coast to be home to 149 species of birds, seven mammals, 10 reptiles, 10 fish, 28 butterflies, five crabs, 15 molluscs and two species of polychaetes. Many species of birds, the survey had noted, were 'globally threatened'. It pointed out that the Mahul creek was recipient to a variety of wastes which flowed in from Thane Creek (which the Mahul creek is connected to) and had noted that the Mahul Creek itself received a lot of "organic sewage, effluents from oil refineries, nuclear wastes from Bhabha Atomic Research Centre (BARC), and wastes from Rashtriya Chemical Fertilizers (RCF)", concluding that there was an urgent need for a detailed study to understand the impact of these on the area's flora and fauna. Other threats noted included mangrove deforestation and land-filling (reclamation) made by amending Coastal Regulation Zone rules.

The sustainable development model for the mining and energy sectors began in 1993 with regulations and procedures for the gradual reduction of pollution, which include economic development policies and environmental protection. The mining industry must comply by adjusting its ongoing operations to permissible effluent levels and its new operations by using cleaner technologies. The DGAA evaluates and proposes the environmental regulations for the mining and energy sectors, which include the maximum emission levels that are compatible with the internationally accepted limits set by the United Nations and the World Bank, approves environmental impact assessments for new operations and environmental adjustment and management programs for ongoing ones, and administers the national environmental information system. The MEM is authorized to manage environmental affairs in the minerals sector, such as establishing the environmental protection policy and maximum allowable levels for effluents, signing environmental administrative stability agreements, overseeing the impact of operations determining responsibilities, and imposing administrative sanctions.

Lawsuits were filed against U.S. Steel, which never acknowledged responsibility for the incident, calling it "an act of God". While the steel company did not accept blame, it reached a settlement in 1951 in which it paid about $235,000, which was stretched over the 80 victims who had participated in the lawsuit, leaving them little after legal expenses were factored in. Representatives of American Steel and Wire settled the more than $4.6 million claimed in 130 damage suits at about 5% of what had been sought, noting that the company was prepared to show at trial that the smog had been caused by a "freak weather condition" that trapped over Donora "all of the smog coming from the homes, railroads, the steamboats, and the exhaust from automobiles, as well as the effluents from its plants."Staff.

1-2 According to the Notice on the Construction Plan for the Nation's Urban Waste Water Treatment and Recycling Facilities presented in the 12th Five-Year Plan by the General Office of the State Council, which was promulgated on May 4, 2012, the waste water treatment rate in the PRC will further improve by 2015. By the end of 2015, the waste water treatment rate should increase to 100% for municipalities, provincial capital cities and cities specifically designated in the state plan, 85% for other cities, 70% for counties, and 30% for towns. Remaining challenges However, in the rush to construct planning mistakes were made. Demand was overestimated, the construction of sewerage lagged behind the construction of treatment plants, designs were sometimes inappropriate, there was no requirement for pre-treatment of industrial effluents thus affecting the effectiveness of treatment processes, and the sites chosen for the first priority investments within a river basin were not always those where the highest impact could have been achieved in terms of improving river water quality.

The saline water generated from the irrigated lands and the industrial effluents are collected by the LBOD canal network from the lower reaches of the Old Nara river or Puran river to discharge by gravity flow to the sea. Also bore wells are used to pump saline water in to the LBOD or the Old Nara river streams to depress the saline ground water level at safe depth or prevent waterlogging. As most of the cultivated lands are located on the left side of the Indus river, LBOD would be the predominant means of discharging the river salt load to the sea once the Indus river waters are fully put to use without letting the Indus river water overflow to the sea from the Kotri barrage which is the last barrage across the river. Effective usage of LBOD is crucial to preserve/enhance the soil fertility in lower reaches of Indus basin area or Sind province or Indus River Delta for discharging adequate salt load to the sea.
