Well Water Testing in Independence

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 year, and arsenic and lead at least once.

Independence is a rural west-Hennepin city of acreage and hobby-farm properties around Lake Independence. Housing here runs to acreage and hobby-farm properties, across the rural parcels around Lake Independence and Lake Sarah.

Well water in Hennepin County

Hennepin County has no MDA township nitrate report on the schedule page, so there is no county well percentage to cite. MDH says about 10 percent of Minnesota private wells have arsenic above 10 ug/L, with levels varying over short distances, and that shallow and sand-aquifer wells are most exposed to nitrate. Boiling does not remove nitrate; it concentrates it. MDH lists coliform yearly, nitrate every year, and arsenic and lead at least once.

When to test your water

  • Every yearColiform bacteria and nitrate, the basic safety checks for a private well. Nitrate can come from fertilizer, septic systems and animal waste.
  • At least onceArsenic and lead. Arsenic can differ even between neighboring wells.
  • Before a baby drinks the waterColiform bacteria, nitrate, arsenic, lead and manganese. MDH recommends testing a private well for all five before a baby drinks the water.
  • When you buy a homeA full baseline while you can still ask questions or negotiate.
  • After flooding or well workFlooding and repairs to the well are reasons to test again.
  • When taste, color or smell changesMDH says a change in taste, smell or look is a reason to test for coliform bacteria.
  • Near a fuel tank or industrial siteVOCs, plus DRO for diesel and heating oil. MDH says to consider a VOC test if the well is near fuel tanks or a commercial or industrial area.
  • City water in an older homeLead. MDH says homes built before 1940 may have lead service lines, and plumbing parts made before 1986 may contain lead.

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 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 Hennepin County homes with private wells need arsenic testing?
MDH says about 10 percent of Minnesota private wells exceed 10 ug/L arsenic and that it can vary a lot between nearby wells, so it advises testing at least once.
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.
What does an Independence inspection usually include?
More than the house — most properties here are acreage with private wells, septic systems and outbuildings, and lakeshore parcels on Independence or Sarah add shoreline drainage to the read.
How do I get nitrate out of my well water?
MDH recommends first having a licensed well contractor inspect the well and removing nitrate sources on your property. Home treatment can follow. MDH's guidance lists anion exchange, reverse osmosis, and distillation among options, and advises certified units. Babies under six months should still not drink treated water, and retest after treatment.
Should I test for E. coli when buying a house with a well?
A bacteria test is a standard way to check a private well, and CDC advises well owners to test for coliform bacteria and E. coli. Results reflect the day of sampling, and an accredited laboratory analyzes the sample. A positive result can be addressed through disinfection, retesting, and inspection of the well.
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.
