Water pollution from surface coal mining has degraded more than 22 percent of streams and rivers in southern West Virginia to the point they may now qualify as impaired under state criteria, according to a new study by scientists at Duke and Baylor universities.
The study, published this week in the peer-reviewed journal Environmental Science & Technology, documents substantial losses in aquatic insect biodiversity and increases in salinity linked to sulfates and other pollutants in runoff from mines often located miles upstream.
“Our findings offer concrete evidence of the cumulative impacts surface mining is having on a regional scale,” said Emily S. Bernhardt, associate professor of biogeochemistry at Duke’s Nicholas School of the Environment. “The relationship is clear and direct: The more mining you have upstream, the higher the biological loss and salinity levels will be downstream, and the farther they will extend.”
Numerous recent studies have demonstrated the water-quality problems caused at or near the site of individual surface coal mines, Bernhardt noted. So she and her team “set out to understand how the large and growing number of surface mines is affecting water quality throughout Appalachia.”
They used NASA satellite images and computer data to map the extent of surface mining taking place across a 12,000-square-mile area of the southern West Virginia coalfields between 1976 and 2005.
They found that companies had converted more than 5 percent of the land into mine sites and buried 480 miles of streams beneath adjacent valley fills during this period.
By overlaying the map with chemical and biological data from 223 streams the West Virginia Department of Environmental Protection sampled in the study area between 1997 and 2007, the researchers determined that pollution runoff from the mines could substantially degrade more than 1,400 miles of streams in the region – four times the length of streams buried below the valley fills.
“It’s important to recognize that surface coal mining pollution doesn’t stop at mine-permit boundaries,” said Brian D. Lutz, a postdoctoral associate in Bernhardt’s lab.
“Our analysis suggests that mining only 5 percent of the land surface is degrading between 22 percent and 32 percent of the region’s rivers,” he said.
Substantial declines in insect diversity began to occur when companies had mined as little as 1 percent of upstream land, the analysis showed. In areas where companies had converted about 5 percent of the land into mines, sensitive species such as mayflies and stoneflies had vanished or declined to an extent that the streams would qualify as biologically impaired under criteria set by the state of West Virginia.
The designation means the streams could be placed on a list of waterways that the state must take steps to rehabilitate.
“What is so compelling is that we found many different types of organisms are lost downstream of surface coal mines, and most of them begin to disappear at similar levels of mining,” said Ryan S. King, associate professor of biology at Baylor. “Our analysis shows that coal mining is leading to widespread declines in aquatic biodiversity in Appalachian streams.”
Lutz and King co-authored the paper with Bernhardt. Other coauthors were John P. Fay, instructor of geospatial analysis at the Nicholas School; Catherine E. Carter, a 2010 master’s graduate of the Nicholas School, now at TetraTech; Ashley M. Helton, postdoctoral associate in Duke’s Department of Biology; John Amos of SkyTruth; and David Campagna, of Campagna & Associates.
The study was supported by unrestricted gifts in support of research from The Foundation for the Carolinas and the Sierra Club, and through a contract to Amos and Campagna from Appalachian Voices.

Over the past several decades, U.S. industries have injected more than 30 trillion gallons of toxic liquid deep into the earth, using broad expanses of the nation’s geology as an invisible dumping ground.
No company would be allowed to pour such dangerous chemicals into the rivers or onto the soil. But until recently, scientists and environmental officials have assumed that deep layers of rock beneath the earth would safely entomb the waste for millennia.
There are growing signs they were mistaken.
Records from disparate corners of the United States show that wells drilled to bury this waste deep beneath the ground have repeatedly leaked, sending dangerous chemicals and waste gurgling to the surface or, on occasion, seeping into shallow aquifers that store a significant portion of the nation’s drinking water.
In 2010, contaminants from such a well bubbled up in a west Los Angeles dog park. Within the past three years, similar fountains of oil and gas drilling waste have appeared in Oklahoma and Louisiana. In South Florida, 20 of the nation’s most stringently regulated disposal wells failed in the early 1990s, releasing partly treated sewage into aquifers that may one day be needed to supply Miami’s drinking water.
There are more than 680,000 underground waste and injection wells nationwide, more than 150,000 of which shoot industrial fluids thousands of feet below the surface. Scientists and federal regulators acknowledge they do not know how many of the sites are leaking.
Federal officials and many geologists insist that the risks posed by all this dumping are minimal. Accidents are uncommon, they say, and groundwater reserves — from which most Americans get their drinking water — remain safe and far exceed any plausible threat posed by injecting toxic chemicals into the ground.
But in interviews, several key experts acknowledged that the idea that injection is safe rests on science that has not kept pace with reality, and on oversight that doesn’t always work.
“In 10 to 100 years we are going to find out that most of our groundwater is polluted,” said Mario Salazar, an engineer who worked for 25 years as a technical expert with the EPA’s underground injection program in Washington. “A lot of people are going to get sick, and a lot of people may die.”
The boom in oil and natural gas drilling is deepening the uncertainties, geologists acknowledge. Drilling produces copious amounts of waste, burdening regulators and demanding hundreds of additional disposal wells. Those wells — more holes punched in the ground — are changing the earth’s geology, adding man-made fractures that allow water and waste to flow more freely.
“There is no certainty at all in any of this, and whoever tells you the opposite is not telling you the truth,” said Stefan Finsterle, a leading hydrogeologist at Lawrence Berkeley National Laboratory who specializes in understanding the properties of rock layers and modeling how fluid flows through them. “You have changed the system with pressure and temperature and fracturing, so you don’t know how it will behave.”
A ProPublica review of well records, case histories and government summaries of more than 220,000 well inspections found that structural failures inside injection wells are routine. From late 2007 to late 2010, one well integrity violation was issued for every six deep injection wells examined — more than 17,000 violations nationally. More than 7,000 wells showed signs that their walls were leaking. Records also show wells are frequently operated in violation of safety regulations and under conditions that greatly increase the risk of fluid leakage and the threat of water contamination.
Structurally, a disposal well is the same as an oil or gas well. Tubes of concrete and steel extend anywhere from a few hundred feet to two miles into the earth. At the bottom, the well opens into a natural rock formation. There is no container. Waste simply seeps out, filling tiny spaces left between the grains in the rock like the gaps between stacked marbles.
Many scientists and regulators say the alternatives to the injection process — burning waste, treating wastewater, recycling, or disposing of waste on the surface — are far more expensive or bring additional environmental risks.
Subterranean waste disposal, they point out, is a cornerstone of the nation’s economy, relied on by the pharmaceutical, agricultural and chemical industries. It’s also critical to a future less dependent on foreign oil: Hydraulic fracturing, “clean coal” technologies, nuclear fuel production and carbon storage (the keystone of the strategy to address climate change) all count on pushing waste into rock formations below the earth’s surface.

To borrow a popular hockey term, Canada has scored a hat trick of the worst kind: Three major oil spills in just over one month.
The culprit this time around is Enbridge, the Calgary, Alberta-based operator of the world’s longest crude oil and liquids pipeline system, situated in Canada and the U.S. On June 19 the company confirmed that about 1,450 barrels (230,000 litres) of crude oil spilled from a pumping station onto farmland near Elk Point, Alberta, according to The Globe and Mail. Fortunately, this spill managed to occur in an area devoid of waterways.
Others haven’t been so lucky.
On June 7, Albertans living downstream from the Red Deer River suffered a scare when a pipeline owned by Plains Midstream Canada ruptured, spewing around 3,000 barrels of oil and posing a severe risk to the drinking water supply of 100,000 people, according to CBC News—Calgary. This spill began beneath Jackson Creek, a tributary of the Red Deer River, ending in Gleniffer Lake and reservoir where the majority of clean-up efforts and monitoring continue to take place.
According to Canada.com, the “province is still advising people not to draw water directly from the river or lake, and it’s telling people not to swim or fish in the lake, either.”
Topping them all is Pace Oil and Gas Ltd., which spilled an estimated 22,000 barrels of oil mixed with water near Rainbow Lake, in the northwestern corner of Alberta, according to Bloomberg.
Because of its remote location, the Pace Oil and Gas spill managed to stay relatively quiet despite being one of the largest and most calamitous oil spills in North America in recent years. The spill released more oil into the environment than the much higher profile Kalamazoo River spill almost two years ago in Michigan, compliments of—yet again—Enbridge, that pumped around 19,500 barrels into the Kalamazoo and surrounding marshes.
The latest Enbridge oil spill near Elk Point is one more to a tally exceeding 800 spills since 1999, and this is the corporation lobbying to build the massive Northern Gateway Pipeline stretching from Bruderheim, Alberta to Kitimat, British Columbia—crossing the Northern Rocky Mountains and innumerable streams, marshes and vital wildlife habitat.
Will we ever learn from this ongoing train wreck? If history is any indication—and it always is—the answer is probably not. Here in the U.S., we still suffer the relentless indignities of elected officials and company men assuring us that projects such as the Keystone XL pipeline pose no risk to the millions who depend upon the Ogallala aquifer for drinking water.
Perhaps a trip north to Gleniffer Lake might put things in perspective, or a trip to our own southern shores along the Gulf of Mexico. But clearly, this debate isn’t about logic or learning from our mistakes at all.

Humanity’s unquenchable thirst for fresh water is driving up sea levels even faster than melting glaciers, according to new research. The massive impact of the global population’s growing need for water on rising sea levels is revealed in a comprehensive assessment of all the ways in which people use water.
Trillions of tonnes of water have been pumped up from deep underground reservoirs in every part of the world and then channelled into fields and pipes to keep communities fed and watered. The water then flows into the oceans, but far more quickly than the ancient aquifers are replenished by rains. The global tide would be rising even more quickly but for the fact that manmade reservoirs have, until now, held back the flow by storing huge amounts of water on land.
“The water being taken from deep wells is geologically old – there is no replenishment and so it is a one way transfer into the ocean,” said sea level expert Prof Robert Nicholls, at the University of Southampton. “In the long run, I would still be more concerned about the impact of climate change, but this work shows that even if we stabilise the climate, we might still get sea level rise due to how we use water.” He said the sea level would rise 10 metres or more if all the world’s groundwater was pumped out, though he said removing every drop was unlikely because some aquifers contain salt water. The sea level is predicted to rise by 30-100cm by 2100, putting many coasts at risk, by increasing the number of storm surges that swamp cities.
The new research was led by Yadu Pokhrel, at the University of Tokyo, and published in Nature Geoscience. “Our study is based on a state-of-the-art model which we have extensively validated in our previous works,” he said. “It suggests groundwater is a major contributor to the observed sea level rise.” The team’s results also neatly fill a gap scientists had identified between the rise in sea level observed by tide gauges and the contribution calculated to come from melting ice.
The drawing of water from deep wells has caused the sea to rise by an average of a millimetre every year since 1961, the researchers concluded. The storing of freshwater in reservoirs has offset about 40% of that, but the scientists warn that this effect is diminishing.
“Reservoir water storage has levelled off in recent years,” they write. “By contrast, the contribution of groundwater depletion has been increasing and may continue to do so in the future, which will heighten the concerns regarding the potential sea level rise in the 21st century.” Nicholls, who was not part of the research team, said there are a wide range of projections of future sea level. “But this work makes one worry about the uncertainty at the high end more,” he said.
The researchers compared the contribution of groundwater withdrawal and reservoir storage to the more familiar causes of rising sea level: ice melted by global warming and the expansion of the ocean as it warms. The pumping out of groundwater is five times bigger in scale than the melting of the planet’s two great ice caps, in Greenland and Antarctica, and twice as great as both the melting of all other glaciers and ice or the thermal expansion of seawater.
The scale of groundwater use is as vast as it is unsustainable: over the past half century 18 trillion tonnes of water has been removed from underground aquifers without being replaced. In some parts of the world, the stores of water have now been exhausted. Saudi Arabia, for example, was self-sufficient in wheat, grown in the desert using water from deep, fossil aquifers. Now, many of the aquifers have run dry and most wheat is imported, with all growing expected to end in 2016. In northern India, the level of the water table is dropping by 4cm every year.

For over 500 years, the Wixaritari Indians of Mexico have suffered from poverty, malnutrition and racism – today, they are also victims of global climate change.
For this ancient indigenous people living in the Sierra Madre Occidental mountain range of northwestern Mexico, droughts are growing more severe and more frequent, until now many communities have little or no water supply.
Climate change is affecting the Sierra Madre Occidental, with bigger droughts each year. The current drought has lasted for two years, making life much more difficult and increasing poverty in Wixaritari communities.
Drought has more serious consequences for the Wixaritari than it does for people in the cities, who are served by water pipes from large lakes.
In the Wixaritari communities, water scarcity has become the main issue. Women, old and young, walk many miles every day seeking a natural water source. They carry plastic bottles on their backs, hoping they can fill them all to supply the thirsty children awaiting their return – the children who are their most valuable treasures.
“We are looking for people to help our community. We don’t have water. We want to see if we can construct a dam,” says Urra Muire, a Wixárika leader who lives in the community of San Andres.
“It does not matter if help comes from Mexico, or from our brothers in the north or there in the other side in Europe. We are asking to whosoever that might come to help us so we can deal with the water problem,” says Muire.
“It is the challenge that I must overcome to help my people,” Muire says. “Since there is no water, wherever I go I speak of my community’s necessity. I want the whole world to be aware.”
Some Wixaritari communities do have a water supply based on a pump, hose and storage tank, but none are able to cleanse the water through an effective water treatment process.
Their water is contaminated with pesticides and mining residues as well as bacteria and organic compounds. As they have no water treatment, no contaminant is removed.
“Even though there is enough water in some of the communities; conducting, treating and storing it are three specific necessities,” says Omar Chiquete Anaya, community development coordinator for Desarrollo Integral de la Familia, or family integral development, in Jalisco’s Wixárika region.
“Water has become the main issue for this people,” says Anaya, a committed person who tries to alleviate Wixárika poverty every day.
