NJDEP Publishes Interim Soil Remediation Standards for PFAS Substances
October 17, 2022
Today, the New Jersey Department of Environmental Protection (NJDEP) published in the New Jersey Register Interim Soil Remediation Standards for four per- and polyfluoroalkyl substances (PFAS): PFNA, PFOA, PFOS and GenX.
NJDEP indicated that because there were no previous soil remediation standards for these compounds, there will not be a phase in period for these standards and they should be applied immediately.
Open cases with potential PFAS concerns should be evaluated relative to the interim standards. As indicated on the NJDEP’s Interim Remediation Standards webpage, the interim standards are as follows
SRS: Ingestion-Dermal Residential
SRS: Ingestion-Dermal Non-Residential
SRS: Migration to Ground Water
Soil Leachate Remediation Standard: Migration to Ground Water
Default Migration to Ground Water standards for these PFAS compounds have not been developed. As a result, NJDEP will expect a site-specific Migration to Ground Water evaluation using the Synthetic Precipitation Leaching Procedure for each Site or Area of Concern (AOC) where a PFAS soil investigation is required. The NJDEP has not yet developed standards for the Inhalation Exposure Pathway due to insufficient inhalation toxicity information
Verdantas staff will attend the NJDEP’s technical training on implementation of the new standards in November so we can continue to support our clients in complying with the new standards.
