Identification of the Source of Per and Polyfluoroalkyl Substances (PFAS) Detected in Multiple Municipal Drinking Water Supply Wells in a Massachusetts Town Using Several Forensic Lines of Evidence 

Bryan Massa, LSP, Principal and Regional Manager, HRP Associates, Inc.

PFAS was detected in multiple municipal drinking water supply wells throughout a Massachusetts town at concentrations exceeding the applicable regulatory standard.  The source of the PFAS contamination was originally unknown. A group of local citizens obtained a technical assistance grant from the Massachusetts Department of Environmental Protection to help identify the PFAS source(s) impacting their drinking water supply.  A comprehensive forensic evaluation was then completed to identify the source(s).  The forensic evaluation included a tiered approach that evaluated the presence or absence of individual PFAS compounds within a large analytical data set, differences in absolute concentrations, relative ratios and patterns, geospatial analysis, and hydrological assessment including particle track analysis.  The information was then used to develop a conceptual site model using multiple lines of evidence documenting the likely PFAS sources.
