PFAS North Runway Location_v1.pdf

This is an environmental assessment map depicting PFAS (per- and polyfluoroalkyl substances) contamination and AFFF (aqueous film-forming foam) historical use at a facility. The map displays an aerial view of a site bisected by a major roadway, with two primary areas of known PFAS soil contamination marked by concentric circles with magenta boundaries and tan diagonal hatching, indicating estimated contamination zones. A red dashed line running diagonally across the map denotes the plume direction or contamination migration pathway.

The map identifies nine monitoring wells across the site: three existing wells (shown as green circles) located within or adjacent to the contamination areas, including PF-HILL13-MW001, PF-HILL13-MW002, PF-HILL13-MW003, PF-HILL11-MW001, and PF-HILL11-MW002, and six new monitoring wells (shown as orange circles) positioned at PF-S121-HW03, PF-SS121-HW02, PF-SS121-HW01, and additional locations to monitor groundwater and soil conditions. The legend indicates that all depicted areas are subject to change as investigation and remediation efforts progress. The scale bar indicates measurements of 0 to 800 feet, allowing for spatial analysis of contamination extent and monitoring well placement relative to the AFFF use and PFAS contamination zones.
