The contaminant of primary concern is per- and polyfluoroalkyl substances (PFAS), which has gained increasing national attention as an emerging contaminant.

Shannon & Wilson is providing groundwater and drinking water monitoring and a limited feasibility study supporting strategies for cleanup and institutional controls. The extent of the groundwater plume is defined; concentrations of PFOA and PFOS in the groundwater plume are stable or decreasing; and remedial selection and institutional controls are recommended at properties within the portion of the groundwater plume with concentrations exceeding the cleanup level.
