Who Pays for PFAS Contamination?
By Ken Sansone
Many parts of the U.S. have recently seen increased testing and regulation of groundwater contaminated with perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), other per- and polyfluoroalkyl substances (PFAS), or similar chemicals. For example, several northeastern states, including New Jersey, Massachusetts, and New Hampshire, have recently enacted regulations limiting PFOA or PFAS in drinking water to concentrations less than the low double digits in parts per trillion (ppt), while California has ordered the testing
of drinking water supply wells near suspected PFAS sources and required notice of detections of PFOA or PFOS above concentrations in the single digits in ppt.
