By Duke University 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. ...

By Abrahm Lustgarten / ProPublica 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. ...

By EcoWatch 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. ...

By Damian Carrington / The Guardian 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. ...

By Juan Pablo García Medina / Environment News Service 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. ...

By Amazon Watch Grassroots opposition is mounting as ConocoPhillips’ plans to drill for oil within the fresh-water source for Peru’s largest rainforest city, Amazon Watch said today on the occasion of the company’s annual shareholder meeting in Houston, Texas. Conoco is currently advancing plans to drill exploratory oil wells in Blocks 129 and 123, found within one of the most ecologically sensitive regions in the world. According to a May 2012 map produced by PROCREL, the Loreto regional environmental authority, ConocoPhillips is planning a total of 16 oil platforms and 48 wells between Block 129 and the adjacent Block 123. Thirteen of these platforms are found within the Upper Nanay-Pintuyacu-Chambira Regional Conservation Area. ...

By Natural Resources Defense Council All currently available options for dealing with contaminated wastewater from fracking are inadequate to protect human health and the environment, but stronger federal and state protections can better safeguard against the threats posed by this byproduct, according to a new report from the Natural Resources Defense Council (NRDC). The report reveals how gas companies in Pennsylvania disposed of more than 30 million gallons of wastewater last year and details the dangers presented by the disposal methods used. ...

By Pesticide Action Network Results released today from water sampling across four Midwestern states – Illinois, Nebraska, Iowa and Minnesota – indicate that the endocrine disrupting pesticide atrazine is still being found in drinking water at levels linked to birth defects and low birth weight. Syngenta, one of the world’s largest pesticide corporations, has continued to promote the use of the chemical, despite growing concerns from independent scientists. The US Environmental Protection Agency will weigh these findings as it continues its re-evaluation of the chemical in the coming months. ...

By Abraham Lustgarten / ProPublica A new study has raised fresh concerns about the safety of gas drilling in the Marcellus Shale, concluding that fracking chemicals injected into the ground could migrate toward drinking water supplies far more quickly than experts have previously predicted. More than 5,000 wells were drilled in the Marcellus between mid-2009 and mid-2010, according to the study, which was published in the journal Ground Water two weeks ago. Operators inject up to 4 million gallons of fluid, under more than 10,000 pounds of pressure, to drill and frack each well. ...

By Environment News Service Thousands of Peruvians protesting in the streets of Cajamarca against a proposed gold and copper mine say they will continue their demonstrations every day until the government rejects the development. They fear the surface open pit mine would pollute their water supplies and destroy the region’s environment. The object of their anger is the Conga Project, located north of the Peruvian Andes 73 km (45 miles) northeast of the city of Cajamarca, at elevations ranging from 3,700 to 4,260 meters (12,140 to 13,980 feet). The mine would straddle two provinces, Cajamarca and Celendin. ...
