NJDEP Issues Interim Remediation Standards for PFAS in Soil

At a Glance


On October 17th, 2022, the New Jersey Department of Environmental Protection (NJDEP) issued interim soil remediation standards for four PFAS compounds. The standards apply to residential and non-residential sites/areas of concern.

Four compounds have new standards for the ingestion-dermal exposure pathway:

  • Perfluorononanoic acid (PFNA)
  • Perfluorooctanoic acid (PFOA)
  • Perfluorooctane sulfonate (PFOS)
  • Hexafluoropropylene oxide dimer acid and its ammonium salt (GenX).

Three compounds also have leachate standards for the migration to ground water pathway: PFNA, PFOA, and PFOS. Soil remediation standard for the MGW pathway are to be derived on a site/area of concern basis using these new interim leachate standards.

The full document with explanation for the science behind the standards is available in this PDF, and NJDEP has updated its Site Remediation Program website with the criteria, reporting limits, and fact sheets.
