Introduction
In a bold move to confront the rising threat of “forever chemicals,” the City of Tustin has officially launched a state-funded PFAS treatment system – positioning itself at the forefront of California’s fight for safe, modern drinking water.
PFAS, or per- and polyfluoroalkyl substances, are man-made chemicals linked to cancer, liver damage, and developmental issues. Found in firefighting foams, industrial discharges, and even household products, these persistent contaminants have infiltrated water systems across the U.S. – and Southern California is no exception.
What Tustin Just Did
A Turnkey PFAS Defense System
Tustin’s new system, funded by the State Water Resources Control Board, uses advanced resin-based treatment to strip PFAS from groundwater supplies.
The system is designed to meet California’s response levels of 10 ppt for PFOA and 40 ppt for PFOS – some of the most stringent standards in the country.
The treatment facility is capable of processing millions of gallons daily, restoring safe access to drinking water for thousands of residents.
Why PFAS Matters Now
PFAS compounds don’t break down in the environment and bioaccumulate in human bodies.
California has ramped up testing and regulation, requiring utilities to notify the public when PFAS exceed specified thresholds.
Tustin had previously shut down wells due to PFAS levels – this new system brings those wells back online safely.
State–Local Collaboration in Action
Tustin’s rollout is part of a broader $160 million state initiative to support PFAS mitigation in vulnerable communities.
Public agencies, including the Department of Water Resources and the Office of Environmental Health Hazard Assessment, played a key role in vetting and funding the project.
Setting the Standard for Other Cities
Tustin’s success story sends a message: clean water is a solvable challenge with the right political will, funding, and technical expertise.
As federal PFAS regulations loom in 2026, other municipalities will need to follow suit – or face major compliance and health crises.
