The surface water plastic in the Arctic Ocean currently accounts for only about 3 percent of the total, but the authors suggest the amount will grow and that the seafloor there could be a big sink for plastic.

Unlined impoundments in coal ash sites may not restrict toxic pollutants from seeping into surrounding groundwater, rivers and lakes, and impoundments that are in poor condition are more likely to leak and contaminate groundwater, surface water or surrounding property.

Because these regions are home to more than half of the world's population and are heavily dependent on surface water, the authors write, the effects of increased eutrophication are likely to be stark, turning the green revolution rather brown.

The volume of the spill on Wednesday from the McChord Pipeline, which was contained, has not been determined, and none of the leaked fuel has reached surface water in the area, the Washington Department of Ecology said in a statement.

El Niño, for the uninitiated, starts when abnormally warm surface water builds up across a vast stretch of the equatorial Pacific, disrupting circulation in the ocean and the atmosphere and leading to predictable patterns of drought and heavy rainfall worldwide.

For starters, the island has no indigenous land animals and no surface water, so it probably didn't have a permanent human population; instead, Lape believes that it was first visited by skilled sailors from nearby islands, who coveted its marine reefs.
|

More than a quarter of the country's groundwater sources and 18 percent of surface water resources were "extracted beyond a sustainable level in 2017," reported NBC News, describing a 2018 study by the Environment Agency that investigated the UK's water usage.

However, with a drought as severe as the present one, groundwater has been providing as much as 60% of farmers' needs, as ever deeper wells, and more of them, have been sunk to make up for cutbacks in their allocations of surface water.
|

Nearby farmers built small canals without authorization to drain their fields of surface water, redirecting flows toward urban areas and worsening the impact of flooding, said Carlos Salvatico, the mayor of the 7,500-person town in the key agricultural province of Cordoba.

That includes such things as deep, multiyear droughts, in the vein of what's been occurring in California and the southwestern U.S; deliberate overdrawing of surface water supplies, such as the Aral Sea; or overdrawing groundwater, which in some areas has already caused land to sink.

City planners had been braced as recently as February for Day Zero to arrive by April after annual rainfall dropped from an average of 1,100mm in 22009 to just 214mm last year, devastating a provincial supply system reliant, almost entirely, on the collection of surface water.

As that current brings warm surface water up to the Arctic, it seems to be bringing with it plastic waste from more densely populated coastlines, dumping the now-fragmented pieces of plastic in the Arctic, where landmasses like Greenland and the polar ice cap trap them.
|
|
In overturning that rule and issuing a far narrower one that would remove federal protections for waterways that don't flow regularly and wetlands that don't have an immediate surface water connection to larger waterways, the Trump administration has argued that it's a matter of policy rather than of science.
|

Meanwhile, Google's skill in cloud-based data crunching helps illuminate the state of surface water: Google digitized 30 years of measurements from around the globe—extracting some from ancient magnetic tapes—then created an easy-to-use online tool that lets resource-poor countries figure out where their water needs protecting.

"The stability of ice shelves is generally thought to be related to their exposure to warm deep ocean water, but we've found that solar heated surface water also plays a crucial role in melting ice shelves," said lead study author Craig Stewart from New Zealand's National Institute of Water and Atmospheric Research (NIWA).

Previous satellite surveys, the best of which featured a resolution of 270 x 271 feet (2000 x 2184 meters), made it difficult for geologists to discern surface water from ground; the color of water varies greatly depending on depth, presence of sediments and dissolved chemicals, and the angle at which the sunlight hits the surface.

But for this to be an effective method of educating autonomous flight software, it also has to be highly accurate; Microsoft says its simulator takes advantage of recent advances in graphics processing technology to provide accurate virtual versions of real-world details like shadow, glare from the sun, haze and pooled surface water on roads.

Though, as the DNR points out, it amounts to less than a 1 percent increase in the total surface water withdrawals from Lake Michigan, it would result in a loss of 2.7 million gallons per day, mostly due to evaporation (the rest of the water will be treated and then returned to the lake basin).
|
|
First on her environmental agenda is getting rid of Enbridge Line 5, an old oil pipeline that runs through the Great Lakes and could contaminate 20 percent of the world's fresh surface water if it were to leak, consequently tanking Michigan's entire economy, and putting the state's entire ecosystem and population at risk of irreparable harm.
|
|
"There were no off-site impacts, no impact to the soil or groundwater, and the oil did not get into any surface water," said Walsh, adding that this leak isn't indicative of the overall state of the pipeline and "wasn't necessarily surprising," given that similar spills have occurred at other South Dakota pipelines when lines are being started up.

Pollution of ground and surface water from acid mine drainage and contaminated dust and soil from mine dumps have exposed residents living around the mines and on the waste dumps to high concentrations of heavy metals and radiation "that can contribute to immediate and long-term medical problems ranging from asthma and skin rashes to cancer and organ damage," the report said.

" Bob Lynch, an Arizona water law expert, stated, "The designation will only complicate the ability of the United States and the State of Arizona to work together to improve [the Four Forest Restoration Initiative] for watershed purposes and to protect it from catastrophic wildfire...Designation of the monument will tie up not only any future surface water use but any future groundwater use as well.
