Abstract
This chapter provides a review of current remediation technologies for treating environmental media impacted by per-and polyfluoroalkyl substances (PFAS), which are known for their extensive use in various legacy and current applications. These chemicals have the potential to cause impacts in groundwater, surface water, soils, and sediments, and have complex behavior, chemical stability, and distribution in the environment. In this chapter, technologies evaluated include in situ and ex situ treatment of liquids (e.g., drinking water and extracted groundwater) and solids (e.g., soils and spent sorbent media) via various mechanisms, such as sorption/retention, physicochemical separation, and destruction. A total of 25 liquid and 11 solid treatment technologies are reviewed for elements such as performance effectiveness, byproduct generation, cost and energy requirements, and a Technology readiness level (TRL) is determined for each technology. While remediation technologies have evolved quickly, ongoing progress and challenges continue to develop that may impact effective management of PFAS-impacted sites.
