Well Water Testing in Northrop

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.

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

Well water in Martin County

MDA's township testing schedule lists no Martin County report, so there is no county nitrate percentage to quote. MDH says shallow wells, sand aquifers and dug wells with non-watertight casings are the most vulnerable to nitrate, and it notes some southwestern Minnesota townships had over 10% of sampled wells above the EPA standard. Boiling does not remove nitrate; it concentrates it. MDH lists coliform yearly, nitrate every other year, and arsenic and lead at least once. We test those plus 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.
Why does MDH stress nitrate for shallow wells?
MDH lists shallow wells, sand aquifers and dug wells with non-watertight casings as the most vulnerable to nitrate. The 10 mg/L standard matters most for infants under six months. Boiling raises the concentration. We test nitrate on an accredited report, and MDH lists it every other year for private wells.
Do you cover Northrop?
Yes — Northrop 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. Martin County is EPA Radon Zone 1, so a 48-hour test rides along on most visits.
