Nationwide Assessment of Cost Impacts to the Clean Water Agencies Triggered by PFAS

by Pooja Sinha

Stantec Institute for Water Technology & Policy

The National Association of Clean Water Agencies (NACWA) initiated a membership survey in 2022 to estimate cost impacts attributable to the presence of per-and polyfluoroalkyl substances (PFAS) in wastewater and biosolids. The survey collected 103 agency responses that geographically represent 40 states. The survey found an average solids management cost increase of 62% reported by PFAS-impacted agencies, based on annual cost per dry ton produced. This cost increase was significantly higher than the average cost increase of 15% reported by agencies without any identified cost driver but is similar to the 67% cost increase reported by agencies experiencing limitations to biosolids disposal options not specifically attributable to PFAS. This presentation will summarize the survey findings, differences in financial implications based on regionally specific PFAS regulations, the case study findings, and will provide recommendations for agencies considering PFAS in future financial planning efforts.
