Well Water Testing Around Duluth, MN
The usual reason to test a well is a direct one: is the water safe to drink? People also test after buying a home, after a new well is drilled, or when they already have a reason to worry about nitrate, arsenic, or bacteria. A water test is a lab result. It is not a physical inspection of the cap, the casing, or the pump. This is a free referral service, not a well contractor and not a laboratory. A local well professional receives your request, gets in touch about it, and handles the work on their own terms, including how the sample is taken and which lab they use.
When you might need it
When you want to know if the water is safe to drink, when you are buying or selling a home with a well, when a new well has just been built, or when you have a reason to test for bacteria, nitrate, or arsenic.
What the work usually involves
- A conversation about which tests you need, including the tests MDH recommends for private wells and the tests Minnesota requires on a new potable well.
- Collection of the sample, or clear instructions for how it must be collected, depending on the provider and the lab.
- Results you can keep, and a referral to treatment if a test has already found a problem you want to address.
This site does not publish testing prices. Any price comes from the provider or the lab, not from this site.
What MDH recommends, and what a new well requires
The Minnesota Department of Health recommends testing private wells for coliform bacteria and nitrate every year, and for arsenic at least once. That is a recommendation for current well owners, not a property-transfer mandate. Minnesota does not require a water test when a house changes hands; the home sale page covers the disclosure rules that do apply, and MDH still recommends that buyers test for bacteria, nitrate, and arsenic.
New potable wells are a stricter case. Minn. R. 4725.5650 already requires tests for total coliform bacteria, nitrate-nitrogen, and arsenic on a newly constructed potable well, within 30 days and before human use, with results to the owner and MDH. Details sit on the well drilling page.
Arsenic is not rare in Minnesota wells. MDH's arsenic page states that arsenic has been detected in about 40 percent of new wells drilled since 2008, and that about 10 percent of Minnesota private wells are above 10 ug/L (10 micrograms per liter). Those figures are statewide. They are not a Duluth count, and they are not a result for your well. The only way to know what is in your water is to test it.
Official MDH pages: arsenic in well water and nitrate in well water.
Testing is not the same as a well inspection
A lab test answers questions about the water. It does not, by itself, tell you whether the cap and casing are sound, or whether isolation distances are what they should be. If you are in the middle of a sale, you may want both. MDH recommends that buyers have a contractor inspect the cap, the casing, and isolation distances, in addition to the water tests.
What to have ready when you request help
A town or address, and what you want tested (or the fact that you want the usual private-well tests), is enough. If you have an older lab report, include it, with the date. If this is a new well, say so, because the required first tests are specific. If a previous test already found a problem and you want treatment, go to the treatment page rather than repeating this one.

FAQ
How often should I test a private well?
MDH recommends coliform bacteria and nitrate every year, and arsenic at least once. Your own situation may call for additional tests; this page does not invent a longer list. A professional or MDH can help you decide what else, if anything, to add.
Is a water test required when I buy or sell a house in Minnesota?
Minnesota does not require a well inspection or a water test at property transfer. Sellers do have well disclosure duties, described on the home sale page. MDH still recommends that buyers test for bacteria, nitrate, and arsenic.
What do the statewide arsenic figures mean for my well?
They mean arsenic shows up often enough in Minnesota that a test is worth doing. About 40 percent of new wells drilled since 2008 have had arsenic detected, and about 10 percent of Minnesota private wells are above 10 ug/L. Those are Minnesota figures, not a result for a Duluth-area well. Only a lab test of your water can speak to your well.
Can this site tell me if my water is safe?
No. Nothing on this site is a lab result or a diagnosis. A test, through a local professional and a lab, is how you get that answer.
