Abstract

This project will estimate PFAS using total fluorine methods in influent and effluents from a pilot-scale adsorption system. The research proposed in this project will address two key objectives: 

(1) Evaluate the removal of PFAS from drinking water supply (groundwater) using broad spectrum measurement methods in a pilot-scale system featuring adsorption-based best available technologies (BATs) including GAC, single-use IX resins and alternative adsorbent, and novel regenerable IX resins. The broad-spectrum methods will include AOF-CIC, AOF-PIGE, and a PFAS-relevant bioassay, as well as ultrashort-chain PFAS analyses, which will be compared to results for targeted (conventional, regulated) PFAS. 

(2) Compare PFAS removal efficiency of single use vs. regenerable adsorbents by quantifying PFAS removal using conventional targeted and broad spectrum PFAS measurement methods.
