UPDATES

New Jersey formalized two sets of PFAS regulations, converting interim standards from 2022-2023 into enforceable requirements:

Site Remediation Standards: Contractors conducting site remediation must now analyze for PFNA, PFOA, PFOS, and GenX when contaminants are unknown or poorly documented. The standards establish soil remediation criteria for ingestion-dermal exposure, inhalation of particulates or vapors, and soil leachate migration to groundwater. This affects how remediation projects are scoped, bid, and executed. Technical guidance: https://dep.nj.gov/srp/guidance/rs/

Groundwater Quality Standards: DEP set a formal limit for GenX chemicals at 0.02 µg/L (practical quantitation level: 0.0075 µg/L), replacing the June 2023 interim standard. The rule also updates cancer descriptor definitions to align with EPA's 2005 framework. Full rule adoption and GWQS information: https://dep.nj.gov/wms/bears/ground-water-quality-standards-gwqs/

Both regulations are effective immediately.
