Well Water Testing in Otsego

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.

Otsego is a fast-growing river city of 2000s subdivisions. Housing here runs to 2000s subdivisions, across the newer river-side subdivisions.

Well water in Wright County

MDA's 2018 township testing in Wright County covered five townships (Clearwater, French Lake, Monticello, Silver Creek and Southside) and 1,315 wells, and 2.4% were over the 10 mg/L nitrate-nitrogen health standard. Township averages hide individual wells. MDH says about 10 percent of Minnesota private wells have arsenic above 10 ug/L and that it is elevated in central and west-central Minnesota. MDH lists coliform yearly, nitrate every other year, and arsenic and lead at least once. We also test 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.
What did MDA find in Wright County wells?
MDA's 2018 initial sampling of five townships found 2.4% of 1,315 wells over the 10 mg/L nitrate health standard. That is a township-level view. Arsenic is separate and can vary from well to well, so MDH advises testing it at least once. We run both on one accredited report. The lab report also covers lead, manganese and iron, so one sample answers several buyer questions.
What do you find in Otsego homes?
2000s builds now reaching their first roof and mechanical replacement cycle, plus the grading settlement common on newer fill.
