Well Water Testing in Isanti

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.

Isanti is a Rum River exurb of 2000s subdivisions on sandy east-central soils. Housing here runs to 2000s subdivisions around a small older core, across the newer subdivisions and the older blocks near the Rum River.

Well water in Isanti County

Isanti County lies in central Minnesota, the region MDH names for the highest percentages of new wells with arsenic detections, so testing for arsenic at least once is sensible. MDH says about 10 percent of private wells statewide exceed 10 µg/L. It also flags central Minnesota counties, with sand-gravel aquifers under row crops, as having more homes on wells at increased nitrate risk. Manganese occurs naturally statewide, and 100 µg/L is MDH's 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.
Should Isanti County well owners worry about arsenic?
MDH says arsenic is in groundwater throughout Minnesota and about 40 percent of new wells since 2008 had a detection, with central and west-central Minnesota showing the highest percentages. About 10 percent of private wells exceed 10 µg/L. Arsenic has no taste or smell, so MDH recommends testing at least once with an accredited lab.
Is Isanti's sandy soil a problem?
Sandy ground drains well but transports radon readily — Isanti County is EPA Radon Zone 2, but a county zone never predicts one house, so we still recommend testing, and we check that sump systems and grading match the seasonal water table.
