Well Water Testing in Balaton

Water testing for Minnesota homes, above all those on a private well. An accredited laboratory tests the water for coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, VOCs (volatile organic compounds), DRO (diesel range organics), 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.

Balaton is a small lake town on the eastern flank of the Buffalo Ridge. Housing here runs to small lake-town homes, across the town core by Lake Yankton.

Well water in Lyon County

MDA's 2018 township testing in Lyon County covered two vulnerable townships, Fairview and Westerheim, and 37 tested wells. Overall 5.4% were at or over the 10 mg/L nitrate-nitrogen health standard: 0.0% in Fairview and 15.4% in Westerheim, so results differ a lot between townships. MDA notes that many homes in these areas are on a rural water supply instead of a private well. MDH lists coliform yearly, nitrate every other year, and arsenic and lead at least once for private wells.

Buying a home with a well in Balaton: the disclosure rules

  1. Before the purchase agreementThe seller discloses in writing every known well and whether it is in use, not in use or sealed.
  2. At closingA well disclosure certificate is signed, unless the deed says the seller knows of no wells.
  3. If a well was hiddenA seller who knew of an undisclosed well can owe the sealing cost and attorney fees if the buyer sues within six years.

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 does the water panel cover?
The panel covers coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, VOCs (volatile organic compounds), DRO (diesel range organics), 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. VOCs and DRO screen for solvents and petroleum, such as fuel from an old oil tank or a nearby leak site. 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. Add it to your home inspection quote. Testing early in your inspection window leaves time to act on the results.
Do Lyon County wells have a nitrate problem?
In MDA's 2018 initial sampling, 5.4% of 37 wells in Fairview and Westerheim townships were at or over 10 mg/L, with 0.0% in Fairview and 15.4% in Westerheim. That is a sample of two townships, so another property can differ. MDH lists nitrate every other year for private wells, and we can include it on an accredited lab report.
My home is on city water. Is water testing still worth it?
Often yes. Community water systems follow EPA testing rules and report results in an annual Consumer Confidence Report, but that report does not measure your own plumbing. MDH and EPA say lead enters mainly from service lines and plumbing materials, and the only way to know is a tap test. MDH recommends an accredited lab, and your utility can say whether your home has a lead service line.
When should a home be tested for DRO or VOCs?
MDH suggests considering a VOC test when a well is near fuel tanks or a commercial or industrial area. MPCA reports petroleum has leaked at about 22,000 Minnesota sites, including home heating-oil tanks, and releases can threaten drinking water and send vapors into buildings. Reasons to test include a nearby leak site, a former or buried fuel tank, or a fuel odor or sheen. MPCA's leaking-tank-site database shows reported releases.
Do you cover Balaton?
Yes — the ridge-flank lake town is within our southwestern range.
How do you remove arsenic from well water?
MDH lists reverse osmosis, distillation, anion exchange, and adsorptive media, plus oxidation or chlorination followed by filtration. Water softeners and activated carbon alone do not remove arsenic, and boiling concentrates it. Choose a unit certified by NSF International, UL, or WQA, and retest the water after installation.
Is there a safe level of lead in drinking water?
No. MDH states that there is no safe level of lead. The EPA action level of 15 parts per billion for public water systems is a point at which a utility must act, not a level considered safe. Babies, children under six, and pregnant women are at highest risk.
What should I look for on a well cap?
The Department of Health asks owners to check whether the well cap is securely attached, broken, or missing, whether the casing has cracks, holes, or corrosion, and whether electrical conduit and other connections are watertight. Under Minnesota Rules 4725.5450, a vent must be screened with openings of 1/16 inch or less and point downward. A damaged cap or vent is a good reason to test for coliform bacteria.
How long does a well last, and are older wells riskier?
The Department of Health says a well's life varies: some last 100 or more years, though 25 to 50 years is more common. It lists wells built before 1974, when the Minnesota Well Code began, as higher risk for microbial contamination, along with leaking dug wells, wells in old frost pits, and wells with corroded casings. If the home's well predates 1974 or sits in a pit, a coliform test is a sensible baseline.
