After the Clean Water Act was passed in 1972, Americans saw a dramatic decline in the pollution of our waterways. But that progress has been eroded. Policies adopted following Supreme Court decisions in 2001 and 2006 undermined the Clean Water Act by creating uncertainty about which waterways were covered. Since then, the EPA has failed to prosecute hundreds of polluters who benefit from the confusion, and countless streams, ponds and wetlands are currently threatened, potentially affecting the drinking water of more than 117 million Americans.
Since 1970, the top 700 meters (roughly 2,296 feet) of the ocean have been heating up 24 to 55 percent faster than scientists have been estimating, the report, published in Nature Climate Change, found—a massive miscalculation that was caused by “poor sampling of the Southern Hemisphere, and limitations of the analysis methods.”
Environmental activists in Appalachia have long suspected that water samples from mountaintop removal mines are sometimes tampered with, but now someone has been caught at it. IMO, this kind of thing is a natural consequence of letting the extractive industry buy politicians…or lab techs or anybody else.
I hope this case strengthens the campaign in Tennessee and other states to keep regulatory authority for coal mining (primacy) with the federal Office of Surface Mining Reclamation and Enforcement, and not the states.
“A Raleigh County man pleaded guilty Thursday to repeatedly faking compliant water quality standards for coal companies, in a case that raises questions about the self-reporting system state and federal regulators use as a central tool to judge if the mining industry is following pollution limits.”
Wildfire can drastically increase the probability of debris flows, a potentially hazardous and destructive form of mass wasting, in landscapes that have otherwise been stable throughout recent history. Although there is no way to know the exact location, extent, and severity of wildfire, or the subsequent rainfall intensity and duration before it happens, probabilities of fire and debris-flow occurrence for different locations can be estimated with geospatial analysis and modeling efforts. The purpose of this report is to provide information on which watersheds might constitute the most serious, potential, debris-flow hazards in the event of a large-scale wildfire and subsequent rainfall in the Sandia and Manzano Mountains.
Phoenix, AZ — Arizona’s Havasupai Tribe and a coalition of conservation groups are praising Judge David Campbell’s decision today to uphold the U.S. Department of the Interior’s 20-year ban on new uranium mining claims across one million acres of public lands adjacent to Grand Canyon. The court ruled that the decision complied with federal environmental laws and that it was not too large, as plaintiffs had argued. At stake is protecting the aquifers and streams that feed the Colorado River and Grand Canyon from toxic uranium mining waste and depletion.
“Water level measurements obtained during this study clearly show that stream levels drive daily trends in groundwater levels. Combined with the detection of pharmaceuticals in groundwater collected several meters away from the stream, these results demonstrate that addition of wastewater to this stream results in unintentional, directed transport of pharmaceuticals into shallow groundwater,” said Paul Bradley, the study’s lead author.
Exposure to endocrine-disrupting chemicals can affect the reproductive system and cause the development of characteristics of the opposite sex, such as eggs in the testes of male fish. Wild- caught fish affected by endocrine-disrupting chemicals have been found in locations across the county. Estrogenic endocrine-disrupting chemicals are derived from a variety of sources from natural estrogens to synthetic pharmaceuticals and agrochemicals that enter the waterways.
