The United States has a PFAS problem. Whether they are raining down from the sky or popping up in food packaging, the mysterious chemicals, also known as Per- and polyfluoroalkyl substances have been finding their way into our bodies and environment—sometimes at concerningly high levels. PFAS are also found in everyday cosmetics, especially in longwear and waterproof makeup items and can  accidentally be ingested overtime. PFAS can even be found in our drinking water.  PFAS are not only dangerous because they build up in the environment and in our bodies, but the chemicals are often associated with low infant birth rates and even cancer according to the EPA. In the past year, some research has connected high rates of PFAS exposure to worse COVID outcomes. Despite being such harmful toxins to people, they’re used regularly and are not historically regulated in the U.S.  To tackle this dilemma, the Environmental Protection Agency (EPA) announced a “Comprehensive National Strategy” to regulate the toxic industrial chemical. The plan describes three main strategies going forward–investing in more research on PFAS, leveraging authorities that can take action to restrict more PFAS chemicals from being released, and accelerating PFAS contamination cleanups. EPA administrator Michael S. Regan pointed out that the agency will work on holding polluters accountable in the announcement. - Popular Science

President Joe Biden’s infrastructure plan proposes to spend $16 billion plugging old oil and gas wells and cleaning up abandoned mines. But there’s no authoritative measure of how many of these sites exist across the nation.  In a recent study, my colleagues and I sought to account for every oil and gas well site in the lower 48 states that was eligible for restoration—meaning that the well no longer was producing oil or gas, and there were no other active wells using that site. We found more than 430,000 old well sites, with associated infrastructure such as access roads, storage areas, and fluid tanks. They covered more than 2 million acres—an area larger than Delaware and Rhode Island combined. - Fast Company

Since Kenneth McDarment was a kid in the 1980s, he’s seen the foothills of the Sierra Nevada change. As a councilman of the Tule River Tribe, a sovereign nation of around 1,000 members living on 56,000-odd acres in the foothills of the Sierras, McDarment deals with everything water-related on the reservation. Today there’s less rain and less snow than there was even a decade ago, which means that the land in the foothills was dangerously dry during the last fire season, when wildfires were sweeping across the state. “If you don’t got water,” says McDarment, “we don’t got nothing.  In 2014, McDarment began looking into getting ahold of some beavers. McDarment hoped that beaver dams would create soggy areas on tribal lands that wouldn’t dry out during heat waves. “We’re hoping that means our land will be less likely to burn during fire season,” he says. “Beavers were here originally. So why not bring them back and let them do the work they do naturally?  There was just one problem—it is illegal to move beavers without a permit. And a permit to move a beaver isn't easy to come by. - Sierra
