PFAS in Residuals Stakeholder Meeting, 2020
Since August 2020, MassDEP has required quarterly monitoring of per- and polyfluoroalkyl substances (PFAS) in residuals that have an Approval of Suitability (AOS) and are permitted to be reused through land application. This increased frequency in monitoring, which had been required annually since January 2019, was implemented to address the need for more information on PFAS characteristics in residuals. Find more information about AOSs.
MassDEP presented at the PFAS in Residuals Stakeholder Meeting on September 29th, 2020, from 1:00 PM - 4:00 PM.
