What to test for in Wagoner County
Private wells are not regulated like public water: EPA advises owners to test their well every year for total coliform bacteria, nitrates, total dissolved solids and pH. Your state's own schedule:
- Oklahoma DEQ recommends testing every year for total coliform bacteria, nitrate/nitrite, conductivity and pH, especially for a new well or after work on the pipes, pressure tank, pump or well casing. If you have taste, odor or staining problems, it suggests testing sulfate, chloride, iron, manganese, hardness and corrosivity (pH and alkalinity) every three years. source
- DEQ says it is preferable to test for coliform bacteria and nitrate/nitrite early in a pregnancy, and recommends testing before bringing an infant home, especially if formula or food is prepared with well water. source
Radon. EPA puts Wagoner County in Zone 3: low potential (average indoor radon may be less than 2 pCi/L). That map is about radon in indoor air, and EPA says it should not be used to decide whether an individual home needs testing. If radon is found in your air and you have a well, EPA suggests testing the water too: see radon in well water.
For anything specific to your home (farms nearby, old plumbing, a new baby, a smell or stain), use the which-tests checklist. When the results arrive, check your numbers against EPA's limits.

PFAS in public water near Wagoner County (public supply, not your well)
This is public water data, not your well. A private well draws its own groundwater, which can have more or less PFAS than the public supply nearby. Only a test of your well tells you.
Under EPA’s fifth Unregulated Contaminant Monitoring Rule (UCMR 5), public water systems sampled their water for 29 PFAS between Jan 3, 2023 and Jun 17, 2026. 8 public systems that serve ZIP codes mainly in Wagoner County reported results. 4 of them had at least one sample with PFOA or PFOS at or above 4.0 ng/L, and 5 had at least one of the 29 PFAS measured at or above its reporting level.
| Public water system | System ID | Highest PFOA (ng/L) | Highest PFOS (ng/L) |
|---|---|---|---|
| Broken Arrow Municipal Authority | OK1021508 | 51.3 | |
| Wagoner Co. Rwd #5 | OK1021528 | 34 | |
| Wagoner Co. Rwd #4 | OK1021529 | 29.5 | |
| Mayes Co Rwd # 2 | OK3004608 | 17.7 |
4.0 ng/L (parts per trillion) is both EPA’s UCMR 5 reporting level for PFOA and PFOS and the number in EPA’s 2024 limit for public water. That limit is judged on a running annual average, so one sample at that level is not a violation. EPA proposed changes to its PFAS rules in May 2026: see PFAS in well water for the current status and who should test a well. To test your own well, find a lab certified for PFAS.
Method: a system counts for this county when it reports serving a ZIP code whose largest land part is in this county, so a system serving several counties counts in each. Source: U.S. EPA, UCMR 5 occurrence data (by state), file dated Oct 15, 2026; downloaded Nov 1, 2026.
