Identifying PFAS as a CERCLA Hazardous Substance: Are You Ready for This?
In this webinar we were pleased to have a special presentation from Ned Witte, Attorney at Godfrey & Kahn, S.C. Ned’s presentation discussed collateral consequences of identifying PFAS as a CERCLA hazardous substance.
This free webinar will discuss the following collateral consequences of identifying PFAS as a CERCLA hazardous substance:
- U.S.EPA CERCLA administrative order and cost recovery authority
- Private party cost recovery and contribution actions
- Impacts on CERCLA five-year reviews and closed sites
- CERCLA defenses and exemptions, including the innocent landowner defense and bona fide prospective purchaser eligibility
- Interface with state PFAS regulations
- Applicable or Relevant and Appropriate Requirements (ARARs)
- Environmental due diligence and the evolution of the ASTM standard to address PFAS and emerging contaminants
- Impacts on transactions and Brownfields
On July 13, 2021, the United States House of Representatives approved the PFAS Action Act, which currently sits before the United States Senate for further action and possible approval. If enacted, the PFAS Action Act would require the United States Environmental Protection Agency to designate two PFAS, known as PFOA and PFOS, as Comprehensive Environmental Response Compensation and Liability Act “hazardous substances” within one year and to make a similar determination on other PFAS substances within five years. Some observers believe that if Congress doesn’t pass PFAS legislation, U.S.EPA may act on its own. Such a CERCLA hazardous substance identification sounds intuitively appropriate, but what are the practical effects? Join Ned Witte, an experienced PFAS lawyer and lecturer, as he discusses collateral consequences of identifying PFAS as a CERCLA hazardous substance.

Six Pilot-Scale Studies Evaluating the In-Situ Treatment of PFAS in Groundwater
Highlights of this free webinar:
- The results from the adsorption-based permeable reactive zones (PRZ) indicated that attenuation of the PFAS was occurring.
- Colloidal activated carbon (CAC)-based PRZ showed the best performance with all the PFAS analyzed being removed to below their respective detection limits (10 ng/L).
- The powdered activated carbon (PAC)-based PRZ showed variable treatment.
- The biochar and ion exchange resins (IER) PRZs initially attenuated the PFAS but then had breakthrough of the C4 PFAS compounds prior to the 6-month post-injection sampling event, with the remainder of the PFAS compounds breaking through prior to the 9-month post injection sampling event.
In this webinar we were pleased to have as a special guest speaker Rick McGregor, President of InSitu Remediation Services Ltd. His presentation discussed six pilot-scale studies evaluating the in-situ treatment of PFAS in groundwater. PFAS are an emerging suite of compounds that have gathered wide-spread attention but have few remedial options. Research and limited field studies suggest that some reagents have promise for the removal of PFAS from groundwater. Six reagents were chosen for pilot testing including hydrogen peroxide, unactivated sodium persulfate, CAC, PAC, biochar and IER to determine if the reagents could be effective at reducing/removing the PFAS. Various PFAS were detected within the pre-treatment groundwater including PFDS, PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFOS and PFNA with concentrations ranging up to 18,000 ng/L for PFPeA. Six pilot-scale permeable reactive zones (PRZs) were created in a shallow, unconfined aquifer situated in a slightly saline, sulfate-iron reducing environment. The groundwater was also impacted with gasoline-range petroleum hydrocarbons along with various additives including MTBE and TBA.
