NH Class B Foam Survey Report

June 19, 2024

During the 2019 legislative season, the NH Legislature adopted Senate Bill 257 relative to perfluoroalkyl and polyfluoroalkyl substances (also known as PFAS) in firefighting foam. RSA 154:8-b, effective September 3, 2019, among other things, required the New Hampshire Department of Environmental Services (NHDES) to survey municipalities throughout the state on the quantitative stock of legacy Class B firefighting foams containing PFAS.

Pursuant to NH RSA 154:8-b, the NHDES in partnership with the New Hampshire Department of Safety, State Fire Marshal’s Office (FMO) issued a Legacy PFAS Firefighting Foam (AFFF) Self Inventory Survey Letter to New Hampshire municipalities on July 31, 2020. The law further required NHDES to estimate the cost of, and institute a take-back program by July 1, 2021 for the purpose of safe and contained disposal of the legacy firefighting foams identified in the survey.

This NH RSA 154 Class B Foam Survey Report has been prepared to summarize the survey findings and provide recommendations and a framework for an AFFF takeback program.
