A military base, surrounding residential area, and commercial properties were suspected to be impacted with per- and polyfluoroalkyl substances (PFAS). Two constituents of aqueous film-forming foam (AFFF), perfluorooctane sulfonate (PFOS), and perfluorooctanoic acid (PFOA), were above the EPA health advisory standards in several groundwater wells, and were impacting residents’ drinking water. CAPE is performing an Expanded Site Inspection and remedial design, and is testing residential well systems at point of use. We are also installing a new deep-water supply well to mitigate PFOS and PFOA impact and providing long-term monitoring. At the residential properties, CAPE is installing water treatment and mitigation systems to remove PFAS constituents from drinking water, and connecting a local community to a public water supply.
