The New Jersey Department of Environmental Protection (NJDEP) has established a new interim specific ground water quality criterion for chloroperfluoropolyether carboxylates (ClPFPECA). The ISGWQC is 0.002 micrograms per liter (μg/L) applies to the total concentration of ClPFPECA congeners in ground water and is enforceable immediately. Similar to other PFAS for which NJDEP has adopted criteria, CIPFPECA congeners are reported to bioaccumulate in humans and are reportedly associated with numerous health endpoints in occupationally exposed workers. The NJDEP Technical Support document indicates this new criterion was adopted to support management and remediation of a single SRP site in southwestern New Jersey that reportedly discharged this compound to the atmosphere with their permitted air emissions, into the Delaware River via their waste water discharge to the local waste water treatment plant, and into groundwater presumably from releases at the facility.
