Last week, the Environmental Protection Agency rolled back Obama-era regulations that had protected drinking water from being contaminated with coal ash, the toxic byproduct of burning coal. Although the coal industry is heralding it as a win, environmentalists say the new rule poses a serious health risk. “This administration is doing everything it can to give coal a free ride, including dismantling our bare minimum protections,” Larissa Liebmann, staff attorney at Waterkeeper Alliance, said in a statement. For decades, the toxic product was dumped into unlined ponds that have the potential to leak and contaminate the drinking water in nearby communities.
