Scientists with the USGS first set out in 2019 to sample 161 waterways as a way of finding potential sources of PFAS contamination from 33 different compounds of the “forever chemicals.'
found PFAS in waterways. It has issued an advisory warning that anglers not eat fish caught in Neshaminy Creek.
Perfluorooctanoic Acid and Perfluorooctane Sulfonate are two of the most widely used and studied chemicals in the PFAS group. But they have been replaced with other PFAS compounds in recent years.There are no federal standards set for PFAS in surface waters, such as streams and rivers. Local waterways that exceeded the proposed levels include the Schuylkill in Pottstown and at Falls Bridge in Philadelphia; Perkiomen Creek near Collegeville; Brandywine Creek at Chadds Ford; Wissahickon Creek at its mouth in Philadelphia and at Fort Washington; Red Clay Creek near Kennett Square; Neshaminy Creek near Langhorne, and Valley Creek near Valley Forge.
“The potential insufficient removal of PFOA and/or PFOS during conventional drinking water treatment techniques” could expose millions of residents to concentrations that exceed the EPA’s proposed standards, the report states.The USGS sampled the streams between Sept. 3 and Sept. 26, 2019, and meshed the data with legal discharges from manufacturing facilities. It also included data for land use.
Only two streams exceeded the EPA’s newly proposed EPA Hazard Index: the 11-mile long Valley Creek and the 41-mile long Neshaminy Creek. The Hazard Index accounts for a larger range of PFAS beyond just PFOA and PFOS that may be found in contaminated drinking water.
