How the Minnesota list marks public samples (whole list). Every lab on this list accepts private-well samples.
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 Minnesota
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.
Minnesota guidance that mentions manganese:
- Coliform bacteria and nitrate every year. Arsenic, lead and manganese at least once. [1]
About 1,176,917 people in Minnesota used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [2] 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: Minnesota.
