Well Water Testing in Darfur

Well water testing for homes on a private well across Minnesota. We collect the sample the right way and send it to an accredited laboratory for coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, iron, hardness, pH, fluoride, sulfate and uranium. The Minnesota Department of Health recommends testing a private well for coliform bacteria every year, nitrate every other year, and arsenic and lead at least once. We also look at the visible wellhead, the pressure tank and the water treatment equipment during the home inspection.

Darfur is a small Watonwan County farm town of older homes. Housing here runs to early-1900s farm-town homes with scattered postwar additions, across the compact town core.

Well water in Watonwan County

MDA sampled Riverdale Township in Watonwan County in 2019, and 6.8% of 44 wells were above the 10 mg/L nitrate standard. That is one township, so a well elsewhere in the county can differ. MDH says southwestern Minnesota tends toward higher manganese, some wells over 1,000 µg/L, and that arsenic occurs statewide, with about 40 percent of new wells since 2008 showing a detection. MDH gives 100 µg/L as the manganese level for infant formula. We test for coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, iron, hardness, pH, fluoride, sulfate and uranium through an accredited lab.

Questions

Common questions.

Who needs well water testing?
Any home on a private well, and above all when you are buying one. A private well is not regulated like a city water system, so the owner is responsible for knowing what is in the water. Testing before closing tells you whether the water needs treatment while you can still ask questions or negotiate.
What do you test for?
Our lab panel covers coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, iron, hardness, pH, fluoride, sulfate and uranium. Bacteria and nitrate are the short-term health checks. Arsenic, lead, manganese and uranium are the ones you cannot see or taste. Iron, hardness, pH and sulfate explain staining, scale, odor and wear on plumbing and appliances.
How often should a well be tested?
The Minnesota Department of Health recommends coliform bacteria every year, nitrate every other year, and arsenic and lead at least once. Test again after flooding, after any work on the well, or if the taste, color or smell of the water changes.
Is well water testing part of the home inspection?
It is an add-on. Book it with the home inspection and we collect the sample the same visit, so the lab results arrive with time to act on them inside your inspection window.
What did MDA find in Watonwan County nitrate tests?
MDA tested Riverdale Township in 2019: 6.8% of 44 wells were above the 10 mg/L standard. MDA's schedule lists a final report for Riverdale published in 2022. It is a single township, and MDH recommends nitrate testing every other year, so test the well you are buying.
Do you cover Darfur?
Yes — Darfur is inside the ring our Mankato-based inspectors cover directly, thermal imaging and mold testing included. The older farm-town stock gets wiring, plumbing, chimneys, roofs and foundations dated precisely, and slow-draining prairie clay keeps grading, sump performance and basement moisture in every report. Watonwan County is EPA Radon Zone 1, so a 48-hour test rides along on most visits.
