BETHLEHEM, Pa. — New research has found widespread and persistent PFAS contamination throughout the Delaware River system, with evidence pollution sources are continuing to feed so-called “forever chemicals” into the watershed.
The study, released late last week by Delaware River Basin Commission, detected per- and polyfluoroalkyl substances in surface water, sediment, fish and blue crab tissue collected throughout the basin, including along the tidal Delaware River.
Researchers found PFAS concentrations generally increased as water moved downstream toward Delaware Bay — even as river volume expanded — suggesting new contamination is entering the river faster than it is being diluted…
