New Jersey NJDEP/EPA-ORD soil PFAS study

Description

The toxicity and environmental persistence of anthropogenic per- and poly-fluoroalkyl substances (PFAS) are of concern globally. To address legacy PFAS concerns in the US, industry developed numerous replacement PFAS that commonly are treated as confidential information. To investigate the distribution of PFAS in New Jersey (NJ), soils collected from across the state were subjected to nontargeted mass-spectral analyses. Ten chloro-perfluoro-polyether-carboxylates were tentatively identified, with ≥3 congeners in all samples. Nine congeners are ≥(CF2)7. Distinct chemical formulas and structures, as well as geographic distribution, suggest airborne transport from an industrial source. Lighter congeners dispersed more widely than heavier, with the most widely dispersed detected in an in-stock New Hampshire sample. Additional data were used to develop a legacy-PFAS fingerprint for historical PFAS sources in NJ. This dataset is associated with the following publication: Washington, J., C. Rosal, J. McCord, M. Strynar, A. Lindstrom, E. Bergman, S. Goodrow, H. Tadesse, D. Pilant, B. Washington, M.J. Davis, B. Stuart, and T. Jenkins. Nontargeted mass-spectral detection of chloroperfluoropolyether carboxylates in New Jersey soils. SCIENCE. American Association for the Advancement of Science (AAAS), Washington, DC, USA, 368(6495): 1103-1107, (2020).
