EOCWD advances PFAS treatment to restore safe groundwater supply
When California lowered notification levels for PFAS, the East Orange County Water District (EOCWD) took immediate action to safeguard its water supply. The district shut down affected wells and partnered with CDM Smith to identify permanent solutions to bring PFAS levels down to non-detect.
Comparison of multiple media options
Testing of various carbons and anion exchange resins helped determine the best-performing treatment media.
Piloting of innovative technologies
EOCWD is piloting advanced techniques to accelerate well restoration and water supply recovery.
Supporting statewide PFAS action
The project aligns with California’s PFAS response plan, supporting compliance with strict notification levels.
The pilot facility, which ran for over 10 months, provided valuable data to guide future PFAS treatment. Through this methodical and science-driven approach, EOCWD is positioning itself to deliver one of California’s most advanced PFAS treatment systems, ensuring resilient, clean and safe drinking water for its community.
