Managing PFAS
As state and federal guidelines/regulations evolve for PFAS management, concerns have emerged regarding the safe disposal of PFAS-concentrated waste streams like aqueous film forming foams (AFFFs), electroplating sludge, or contaminated wastewaters. While some of these waste streams are already managed as hazardous wastes due to concentrations of heavy metals, available technologies for stabilization/solidification of hazardous wastes have not been evaluated for their efficacy in PFAS encapsulation. To understand current PFAS management at hazardous waste landfills and inform the safe disposal of PFAS-concentrated waste streams in the future, the leachability and volatility of PFAS through stabilization/solidification technologies is being examined.
