Abstract
Abstract As a follow‐up to the PFAS Experts Symposium 2 held on June 30 and July 1, 2021, the In situ Remediation Technologies Committee prepared a technical and regulatory review of in situ technologies that are potentially applicable to sites with per‐ and polyfluoroalkyl substances (PFAS) contamination. The technologies included in the review were limited to those that are deemed commercially available and potentially applicable to sites with soil, groundwater, surface water, and sediment contamination. While the scope of commercially available in situ remediation technologies for PFAS remains limited, some in situ adsorption technologies, most notably activated carbon‐based technologies, can be considered fully commercialized. Though questions remain regarding the long‐term effectiveness of these technologies, field applications deployed for at least a half‐decade or more continue to demonstrate effectiveness.
