The federal agency has found forever chemicals at several Superfund sites in Maine that could require new scrutiny. The EPA had not tested for the man-made forever chemicals, known as per- and polyfluoroalkyl substances, or PFAS, until the past five years, and regulations at the time did not mandate that the toxic chemicals be cleaned up. That changed last July when a new federal regulation designated two of the most studied and commonly used PFAS as hazardous substances, requiring them to be remediated if they exceed federal standards.
