THE CHALLENGE
The challenge for municipal utilities
01
A federal MCL is now enforceable
EPA’s 2024 rule set a 4 ppt Maximum Contaminant Level for PFOA and PFOS in drinking water — the first legally enforceable federal PFAS limit.
02
The compliance timeline is still moving
EPA has proposed extending the PFOA/PFOS compliance deadline from 2029 to 2031, and separately proposed rescinding limits on four other PFAS. Utilities are planning under real uncertainty.
03
Legacy infrastructure wasn’t built for this
Most treatment plants were never designed to remove PFAS, and ratepayers are the ones who ultimately absorb the capital cost of retrofitting.
04
Displacement isn’t a long-term answer
GAC and ion exchange media capture PFAS but don’t destroy it — someone still has to dispose of the spent, PFAS-laden media.
THE RECOMMENDED SOLUTION
Concentrate onsite, destroy onsite, discharge clean
WHY THIS APPROACH
Built for ratepayer-funded budgets
Predictable OPEX
Converts an open-ended media-replacement cost into a known, budgetable operating expense.
Meets the MCL without guesswork
Destroys PFAS rather than relocating it, so the compliance picture doesn’t depend on where captured media eventually goes.
Protects public trust
Onsite destruction gives utilities a straight answer when the public asks what happens to the PFAS once it’s “removed.”
Scales to your system
From a single well to a full municipal plant, the same closed-loop approach scales up or down.
REGULATORY CONTEXT
As of mid-2026, EPA’s PFOA/PFOS MCL remains in effect while a proposed compliance-deadline extension and a separate rescission rule for four other PFAS are still under review.
REAL RESULTS
Onsite PFAS removal at the largest WWTP in New Jersey
Passaic Valley Sewerage Commission — a municipal wastewater treatment plant serving 1.4 million people — piloted E2METRIX’s closed-loop Olift® + Obreak® system, demonstrating 93% total PFAS removal and eliminating the need for offsite disposal.
