Maine PFAS Investigation
Preliminary Private Drinking Water Well Results by Town
This table includes all PFAS residential groundwater data collected by the Department or their contractors across all programs, including the sludge and septage land application investigation, closed municipal landfill sites, active commercial sites, and all other remediation-type sites. It also includes self-tester data submitted to and validated by the Department. This is not a complete data set as data is still being compiled and collected. Data will continue to be updated as it becomes available. In some instances, multiple towns are combined as data collected relates to specific sites that cross municipal boundaries.
