Since April 2021, the District has been sampling for PFAS. Results indicate that PFAS continues to be detected in our water sources. However, the District’s PFAS levels are in compliance with the MassDEP’s regulatory standard (not exceeding 20 ppt quarterly).
Maximum Contaminant Level (MCL) compliance is calculated using the average of the monthly samples over a quarter (four quarters including January-March, April-June, July-September, and October-December).
Reference monthly testing results and quarterly compliance for 2025, 2024, 2023, and 2022 below.
