“The Maryland Department of the Environment has completed their St. Mary’s River Pilot Study of per- and polyfluoroalkyl substances (PFAS) and stated in an October 5 press release, “No levels of concern found within study area…” MDE studied surface water at 23 sites in the St. Mary’s River and St. Inigoes Creek, one site in Smith Creek, two sites at the mouth of the Patuxent River, and one site on the eastern shore (Fishing Bay). Levels of individual PFAS compounds detected ranged as high as 6.72 ppt (parts per trillion) for the compound PFOS in the central St. Mary’s River. The State tested for 36 PFAS compounds and total PFAS for this same site was 13.45 ppt.
But a follow-on study last month, funded by Public Employees for Environmental Responsibility (PEER) and the Association, tested oysters at two locations in the St. Mary’s River and found three PFAS compounds.”
