Cameron-Cole was retained to provide regulatory and technical consulting services to evaluate the presence of Per- and Polyfluoroalkyl Substances (PFAS) on airport property owned by the authority. As required by the federal government, the airport conducted extensive testing of Aqueous Film Forming Foam (AFFF) on its property. Cameron-Cole's experts reviewed available records and developed a strategic and phased site assessment approach to comply with the terms of Court requirements regarding data reporting. Cameron-Cole executed a groundwater and soil sampling program in adherence with strict Standard Operating Procedures (SOPs). Other tasks included the development of a comprehensive area well survey using ArcView/GIS to determine potentially completed exposure pathways. Subsequent tasks will include determining the lateral and vertical extent of these substances in media and development of a cost estimate for soil and groundwater remediation for plaintiff cost-recovery purposes. Working with outside environmental counsel and on an aggressive schedule, the client was able to satisfy the deadline for submitting reportable data to the Federal Court. This will allow our client to be part of the class action lawsuit and the initial consolidated case in the Multi District Case of the United States District Court of South Carolina Case MDL 2873. In addition, the phased approach advocated by Cameron-Cole will provide the client with time to evaluate the degree of additional services such as modeling fate and transport of these substances as well as surface water impacts which could affect cost-recovery amounts.
