Civil and Environmental Engineering Master's Project Presentation
The bioaccumulation, chemical persistence, and historic presence in soil / water systems of PFAS leads to unique challenges when it comes time to remediate and redevelop a site. Remediation of PFAS is made especially difficult by the low reactivity and strong carbon-fluorine bonds that make up the chemical structure of PFAS chemicals. Current non-destructive PFAS remediation technologies such as activated carbon, ion exchange and reverse osmosis have been implemented with success in many areas where PFAS contamination is an issue but could destructive techniques be more effective? Research suggests that non-destructive methods currently dominate field applications due to their operational maturity and regulatory acceptance. Destructive technologies have become of interest in research given their potential for permanent PFAS removal. These methods are still largely experimental but using a hybrid approach where non-destructive is coupled with destructive treatment has emerged as a promising pathway to balance the feasibility of these methods while also decreasing cost and increasing effectiveness This review underscores the need for innovation in scalable destructive technologies that minimize harmful byproducts and provide economical solutions. By reviewing non-destructive techniques and further researching how destructive techniques can be implemented, this review provides a perspective on the current state of PFAS remediation and identifies research priorities that will lead to long term solutions in the field.
