The data received could not be readily assessed, as MassDEP has not yet issued criteria to evaluate risk associated with PFAS in wastewater treatment residuals or compost. Further, it is recognized that sampling was not conducted in accordance with current protocols. The Town and its Contractor Waste Options are now performing quarterly monitoring of PFAS in accordance with the recent MassDEP Approval of Suitability (AOS) permit requirement updates. Note that starting in 2019, wastewater residuals and municipal solid waste stopped being used to prepare compost for Town-wide use.
