Reverse osmosis (drinking water)
The treatment category most often matched to dissolved contaminants like lead, arsenic, nitrate, fluoride, and radiological contaminants detected in this system.

The treatment category most often matched to disinfection byproducts (TTHMs, haloacetic acids), chlorine taste and odor, and organic compounds detected in this system.
Shop whole-house systems →Source: U.S. EPA Six-Year Review 4 compliance monitoring data (2012–2019), the most recent nationwide compliance dataset EPA has released, reported at the water-system level. A detection is not a violation. “Avg. vs. limit” compares the average of laboratory detections to the federal MCL or action level; individual faucets can differ — household plumbing affects lead and copper, and a state-certified laboratory test of your own tap is the only way to confirm levels in your home. Treatment categories are general matches, not a certification claim for a specific product and contaminant.
Water Utility: Edmond Pwa
Population Served: 79,408 residents
Data Sources: EPA SDWIS + EPA UCMR5
Report Year: 2026
Edmond, Oklahoma drinking water is supplied by Edmond Pwa. All US public water systems must test drinking water and report results to the EPA under the Safe Drinking Water Act. This report summarizes health-based violations and PFAS detections recorded in federal databases to help you make informed decisions about home water filtration.
EPA Violation History
No health-based EPA maximum contaminant level (MCL) violations on record since 2010 for this utility.
PFAS "Forever Chemical" Detections
PFAS compounds were detected in this water system during EPA's Fifth Unregulated Contaminant Monitoring Rule (UCMR5) testing program (2023-2025). EPA has set maximum contaminant levels of 4 parts per trillion (ppt) for PFOA and PFOS individually.
| PFAS Compound | Level Detected | Solution |
|---|---|---|
| PFPeA | 0.0046 ug/L | PFAS Filters |
| PFHxA | 0.0058 ug/L | PFAS Filters |
| PFOS | 0.0064 ug/L | PFAS Filters |
| PFBS | 0.0047 ug/L | PFAS Filters |
| PFHxS | 0.0035 ug/L | PFAS Filters |
| PFBA | 0.0060 ug/L | PFAS Filters |
Source: EPA UCMR5 occurrence data. Levels in micrograms per liter (ug/L = parts per billion). 1 ug/L = 1,000 ppt.
Should You Filter Your Edmond Water?
Even utilities with no EPA violations may have contaminants present below legal limits but above health guidelines. The EPA sets maximum contaminant levels based on what is feasible and affordable to treat at scale -- not necessarily what carries zero health risk. Many independent health organizations recommend filtration for households with children, pregnant women, or immunocompromised individuals regardless of utility compliance status.

Frequently Asked Questions
Is Edmond tap water safe to drink?
Edmond Pwa is required to meet EPA federal drinking water standards. However, meeting legal standards is not the same as being contaminant-free. Trace levels of disinfection byproducts, PFAS compounds, and other regulated contaminants are common in US municipal water systems.
Does Edmond water have PFAS?
PFAS compounds were detected in this utility's water during EPA UCMR5 monitoring. A certified PFAS filter -- such as reverse osmosis or activated carbon block -- can significantly reduce these compounds at your tap.
What water filter works best for Edmond?
A whole-house carbon block filter removes chlorine, chloramines, and many VOCs. For PFAS, arsenic, and nitrates, a reverse osmosis under-sink system provides the highest reduction rates. Take our free 2-minute quiz to find the right system for your home and budget.
