Group Delta, an NV5 Company, performed a Phase I Environmental Site Assessment (ESA) and Phase II ESA for a West Coast Airport for site redevelopment into open space land. Our team completed the subsurface soil investigation at numerous recognized environmental conditions (RECs) including 13 sites where AFFF was stored, used, and released to the subsurface soils during training and petroleum fire incidents. AFFF is known to contain PFAS which do not degrade appreciably and are regulated by the EPA and other State regulatory agencies. Additional soil investigations to further characterize PFAS in soil are underway to assist remedial action planning and design at the airport.
