FAQs

You asked, we answered!  

This list of Frequently Asked Questions (FAQs) documents the answers for community questions about Nantucket’s Town-wide per- and polyfluoroalkyl substances (PFAS) assessment program activities and public health.  This information was updated March 25, 2021.

With the assistance of CDM Smith, the Town prepared a The PFAS Preliminary Assessment and Planning Approach Report, copy available here.  This report was revised on March 16, 2021 (original dated February 4, 2021) to address an error in Table 6-1 and now includes an errata sheet at the end of the report. A five-page fact sheet that summarizes the report can be found here.
