Well Water Testing in Delavan

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.

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

Well water in Faribault County

MDA's 2018 township testing in Faribault County covered Barber, Prescott and Winnebago townships: 134 wells were tested and none (0%) were over the 10 mg/L nitrate-nitrogen health standard. That is a good result for those townships, but it does not cover the whole county or every well depth. MDH lists coliform bacteria yearly, nitrate every other year, and arsenic and lead at least once. We run those on an accredited lab report along with manganese, iron, hardness, pH, fluoride, sulfate and uranium.

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.
Did MDA find nitrate above the limit in Faribault County wells?
In the 2018 initial sampling of Barber, Prescott and Winnebago townships, 0% of 134 wells tested over the 10 mg/L health standard. Results are township-level, so a specific well can still differ. We test nitrate, and MDH lists it every other year for private wells. Results come back on a report from an accredited lab.
Do you cover Delavan?
Yes — Delavan is a short run from our Mankato base, inside the ring where our own inspectors do thermal imaging and mold testing. Older farm-town homes get wiring, plumbing and foundations dated precisely, and flat prairie clay keeps drainage and basement moisture in every report. Faribault County is Radon Zone 1.
