Well Water Testing in Bock

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.

Bock is a very small Highway 23 railroad-era town between two Rum River watershed brooks. Housing here runs to older frame houses and farmhouses from the railroad years, a handful of newer homes, in a city of 78 people, across the small townsite along Highway 23 and the farm acreages between Bogus Brook and the Vondell Brook tributary.

Well water in Mille Lacs County

Mille Lacs County is in central Minnesota, where MDH reports the highest shares of new wells with arsenic detections. Statewide, about 40 percent of wells drilled since 2008 had a detection and about 10 percent of private wells exceed 10 µg/L. MDA's township results list shows no Mille Lacs County nitrate report, so no county figure is quoted here. MDH also says manganese occurs naturally across the state. Buyers should test coliform bacteria yearly and arsenic at least once. 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.
Is arsenic a known issue for Mille Lacs County wells?
MDH says central and west-central Minnesota have the highest percentages of new wells with arsenic detections, and Mille Lacs County is in central Minnesota. The state figure is about 40 percent of new wells since 2008. Arsenic cannot be seen or tasted, so MDH recommends at least one test with an accredited lab.
Should a house in Bock, with a population of 78, be inspected like a rural property?
Yes. Bock was named by railroad officials and had a post office by 1892, and it is now the smallest city in Mille Lacs County, so most properties are old, quiet and independent. Many homes in the county use private wells and septic systems, and we help you confirm what a specific house has. We date the wiring, plumbing and roof, look at foundation and grading near the two brooks that bracket the town, and check for rodent entry in houses that sit vacant. Mille Lacs County is EPA Radon Zone 2.
