Well Water Testing in Glencoe

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.

Glencoe is the McLeod County seat of older homes and postwar neighborhoods on Buffalo Creek. Housing here runs to older homes and postwar neighborhoods, across the county-seat core along Buffalo Creek.

Well water in McLeod County

McLeod County has no township nitrate report on MDA's results list, so no county-specific figure is available to quote here. What MDH does say applies statewide: arsenic is in groundwater everywhere, found in about 40 percent of new wells since 2008, and about 10 percent of private wells exceed 10 µg/L. MDH also says manganese is natural in Minnesota groundwater, and 100 µg/L is its safe level for infant formula. Nitrate and coliform bacteria are the yearly and every-other-year checks.coli, nitrate, arsenic, lead, manganese, iron, hardness, pH, fluoride, sulfate, uranium, VOCs and DRO (diesel range organics) through an accredited lab.

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.
Which well tests matter most for a McLeod County home?
Follow MDH: coliform bacteria every year, nitrate every year, and arsenic and lead at least once. Add manganese, since MDH gives 100 µg/L as the safe level for infant formula. MDH says arsenic is found statewide, so a county without a published map result still needs a test. Buyers should test at inspection, not after closing.
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 comes up in Glencoe homes?
Older county-seat stock — original services and clay laterals — plus creek-adjacent low ground where grading and sump performance deserve verification.
What is a first-draw lead test?
A first-draw sample is taken after water has sat in the plumbing for at least six hours, so it shows how much lead has dissolved from the plumbing. MDH also describes a flushed sample, taken after running the water for a minute or two. Use an accredited laboratory.
How do you get rid of coliform bacteria in a well?
The usual method is shock chlorination, also called well disinfection. A licensed well contractor can do it, or owners can follow the MDH well disinfection instructions. Afterward, have an accredited lab retest the water. MDH suggests retesting again about two to four weeks later because coliform can regrow, and repeating disinfection if it returns.
How do I find the construction record for my well?
The Minnesota Well Index (MWI), maintained by the Department of Health, is an online database of basic well and boring information that can be searched by map or text. It is the web version of the County Well Index developed with the Minnesota Geological Survey. Most wells built before 1974 will not have records on file. Knowing the construction date helps decide what to test for.
How common is arsenic in Minnesota well water?
The Department of Health says about 40 percent of Minnesota wells have arsenic in the water. It occurs naturally in rocks and soil, levels can differ between wells even within a small area, and you cannot taste, see, or smell it. The EPA limit for community water systems is 10 micrograms per liter. Only a lab test shows the arsenic level in a specific well.
