PFAS
This questionnaire collects the site-specific hydrogeologic and chemical data needed to evaluate the feasibility, sizing, and expected performance of a PFAS Permeable Sorption Barrier (PSB). Information provided through this form supports preliminary design considerations, longevity estimates, and treatment expectations based on subsurface conditions and PFAS loading.
The questionnaire requests details on:
- Barrier dimensions and placement
- Groundwater flow characteristics and porosity
- Influent PFAS concentrations (Method 1633)
- Non-target PFAS and co‑contaminants
- Competitive adsorption factors, including organic compounds and geochemical parameters
- Longevity requirements and anticipated changes in source conditions
Supporting documentation, such as site maps, well logs, and analytical data, may be attached where available. Completing this form enables an efficient technical review and helps streamline next steps in PSB evaluation and implementation.
