Well Water Testing in Biscay

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.

Biscay is a McLeod County village that is the smallest Minnesota city by land area. Housing here runs to small older houses on compact lots in a very small village, with some newer homes, across the entire 0.075-square-mile village along Highway 22, with the South Fork Crow River just to the east.

Well water in McLeod County

McLeod County has no township nitrate report on MDA's results list, so no county-specific figure is available to quote here. What MDH does say applies statewide: arsenic is in groundwater everywhere, found in about 40 percent of new wells since 2008, and about 10 percent of private wells exceed 10 µg/L. MDH also says manganese is natural in Minnesota groundwater, and 100 µg/L is its safe level for infant formula. Nitrate and coliform bacteria are the yearly and every-other-year checks. We test for coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, iron, hardness, pH, fluoride, sulfate and uranium through an accredited lab.

County facts checked September 2026 against: Minnesota Department of Health, Minnesota Department of Health, Minnesota Department of Health, mda.state.mn.us, mcleodcountymn.gov.

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.
Which well tests matter most for a McLeod County home?
Follow MDH: coliform bacteria every year, nitrate every other year, and arsenic and lead at least once. Add manganese, since MDH gives 100 µg/L as the safe level for infant formula. MDH says arsenic is found statewide, so a county without a published map result still needs a test. Buyers should test at inspection, not after closing.
What should I know about a house in Biscay, the smallest Minnesota city by land area?
Biscay was incorporated in 1949 and covers just 0.075 square miles, so every lot is close to its neighbor and to the highway. Homes here sit on small lots and are mostly modest in size. We check grading and roof drainage on tight lots, the age of the furnace and water heater, the panel and branch wiring, and the roof. The South Fork Crow River flows east of the village, so we also look at basement moisture and sump performance after wet seasons.
