8. Does MassDEP have a program to support private (domestic) well testing?

Yes. MassDEP began a Private Well PFAS Sampling Program in November 2020. In February 2021, the Town of Nantucket is being considered to be added to this program. The program selects a representative number of private wells, provides sampling kits to well owners, and pays for the laboratory analysis costs of the PFAS samples. The private well owner is responsible for collecting the sample. 

Before applying, well owners should review and understand the program and the implications of their sampling results. For example, private well water PFAS6 detections of 20 ng/L or above is reportable under MassDEP’s MCP and may require action by the private well owner.

MassDEP will select which wells will be sampled based on priority factors including geographic distribution throughout the town, proximity to potential sources of PFAS, and available funding. Applying for the program does not guarantee your well be included in the program. To apply for consideration, well owners can submit a Private Wells PFAS Sampling Program “Notice of Interest Application Form” on MassDEP’s website.

MassDEP PFAS drinking water standard MCL is 20 ppt for what the regulations call PFAS6, or the sum of six PFAS: perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), perfluoroheptanoic acid (PFHpA), and perfluorodecanoic acid (PFDA), (https://dwp-pfas.madwpdep.org/).
