11. Are septic systems or private wastewater treatment within a Zone II aquifer wellhead protection area regulated for PFAS? If so, how?

No. There is no specific regulation of PFAS in a Zone II aquifer wellhead protection area (refer to glossary) relative to septic systems. However, the MassDEP Title 5 program and land use controls offers general protection to Zone II aquifer areas. Local Boards of Health and MassDEP are the regulatory authorities for septic systems. The Town of Nantucket’s Septic System Resources website (see call-out box) has helpful resources for you to ensure you are doing your part to protect the Island’s resources, including the Zone II aquifer wellhead protection area.
