HRSD’s approach to managing PFAS is multifaceted:

1. Minimize PFAS sources into HRSD facilities from both commercial and residential sources.
2. Implement technologies capable of removing PFAS as part of our multi-barrier approach when producing water for aquifer recharge at SWIFT.
3. Support, lead, and share PFAS research focused on fate and transport of PFAS in wastewater, water reuse, and biosolids.

HRSD regularly publishes quarterly monitoring reports that are available to those interested in SWIFT reuse water quality. In addition, HRSD is currently participating in a variety of studies funded by the Water Research Foundation (WRF) and is assisting EPA as it investigates PFAS fate during solids incineration. For more information on each of these studies, please see the following links:

• Occurrence of PFAS Compounds in US Wastewater Treatment Plants (WRF 5031)
• Investigation of Alternative Management Strategies to Prevent PFAS from Entering Drinking Water Supplies and Wastewater (WRF 5082)
• Investigation of Treatment Alternatives for Short-Chain PFASs (WRF 4913)
• Studying the Fate of PFAS through Sewage Sludge Incinerators (WRF 5111)
