Scripps News A new study from Environmental Working Group scientists found that eating just one freshwater fish could be the equivalent of drinking a month’s worth of water contaminated with PFOS. That’s a set of “forever chemicals” in the same family as PFAS. Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are found in nonstick and water-resistant consumer products. PFAS are commonly referred to as forever chemicals because they do not break down in the environment. “For anyone consuming freshwater fish, we actually think this is likely their largest source of exposure to these compounds,” said David Andrews, EWG senior scientist and one of the study’s lead authors. The scientists analyzed data from over 500 fish fillet samples that were collected across the U.S. from 2013 to 2015 under monitoring programs by…
By Rachel Fritts; EOS Groundwater makes up most of the world’s liquid fresh water and might play a bigger role in sustaining streams and plant life than previously thought. Credit: Dr. Andrew Fisher/Wikimedia Commons, CC BY-SA 4.0. Source: Geophysical Research Letters A large part of the world’s liquid freshwater supply comes from groundwater. These underground reservoirs of water—which are stored in soil and aquifers—feed streams, sustain agricultural lands, and provide drinking water to hundreds of millions of people. For that reason, researchers are keen to understand how quickly surface water replenishes, or “recharges,” groundwater stores. But measuring a vast, fluid, underground resource is easier said than done. In a new study, Berghuijs et al. found that recharge rates might double previous estimates. The research team produced an updated model of groundwater recharge using a recent global synthesis…
E&E News Idaho landowners Chantell and Michael Sackett are behind a new Supreme Court case that could upend Clean Water Act precedent. Pacific Legal Foundation The Supreme Court’s decision today to take a fresh look at the scope of the Clean Water Act could impair EPA’s ability to protect isolated wetlands and ephemeral and intermittent streams. It’s the latest brawl the high court has agreed to tackle with the potential to reshape national environmental policy. “They very well could address this whole issue fresh, what we call de novo, look at it in light of what the language of the statute really means,” said Larry Liebesman, a senior adviser at Dawson & Associates, a consulting firm that specializes in permitting. “With a 6-3 majority conservative, there’s a fair chance they may…
