How the Oklahoma list marks public samples (whole list). Yes/no from ODEQ's 'Commercial Sample' column. ODEQ: "To view laboratories accepting private samples, see the 'Commercial Sample' column". ODEQ does not say whether 'private samples' means household wells, so call first.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for manganese in Oklahoma
Black stains start around EPA's 0.05 mg/L guideline, but the health numbers sit higher and vary by agency, especially for babies on formula. Read our manganese explainer.
Oklahoma guidance that mentions manganese:
- 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. [1]
Prices at Oklahoma DEQ State Environmental Laboratory Services, Lab Services Fee Schedule FY27, effective July 1, 2026 through June 30, 2027 (card payments add a 2.25% merchant fee and a $2 portal fee), as published when checked on 2 Nov 2026. Private certified labs set their own prices.
| Test | Price |
|---|---|
| Private well diagnostics test list (annual list plus calcium, copper, iron, manganese, sodium, hardness) | $175 [2] |
About 356,860 people in Oklahoma used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [3] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Oklahoma.
