‘Forever chemicals’ in thousands of private wells near military sites, study finds

According to the Environmental Working Group, a Washington, D.C.-based nonprofit that analyzed Department of Defense testing data, 2,805 wells spread across 29 states were contaminated with at least one of two types of per- and polyfluoroalkyl substances, or PFAS, above 4 parts per trillion, a limit proposed earlier this year by the Environmental Protection Agency. That new drinking water standard is expected to take effect by the end of the year.
