Well Water Testing in Edgerton

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.

Edgerton is a Dutch-heritage farm town on the high Buffalo Ridge prairie. Housing here runs to Dutch-heritage farm-town homes, across the town core.

Well water in Pipestone County

Pipestone County's township nitrate results from MDA are high. In 2018 initial sampling of nine townships, 48.7% of 115 wells were at or over the 10 mg/L nitrate-nitrogen standard, from 33.3% in Burke to 81.8% in Altona. The highest reading was 73.4 mg/L. MDA notes many homes in these townships are on a rural water supply, and Lincoln Pipestone Rural Water lists Pipestone County in its service area. For a private well, nitrate every year is MDH's guidance.

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.
How high is nitrate in Pipestone County wells?
MDA's 2018 initial sampling of nine Pipestone County townships found 48.7% of 115 wells at or over the 10 mg/L health standard. Township rates ran from 33.3% in Burke to 81.8% in Altona, with a high of 73.4 mg/L. That is a sample, not a verdict on one property, but it is a strong reason to test nitrate on a private well.
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 Edgerton?
Yes — the high-prairie town's older housing gets a full local inspection, with wind-exposure wear on roofs and siding in mind.
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 does a positive total coliform result mean in well water?
Coliform bacteria are common on the ground surface, so a positive result suggests surface contamination has entered the well. Most coliform bacteria do not cause disease, but their presence suggests disease-causing microorganisms may also be in the water. MDH advises using boiled or bottled water until the well is disinfected and a retest comes back negative.
What is a well pit and why is it a concern?
Older wells were often finished in pits below ground so pipes would not freeze. The Department of Health says pits are a health hazard because flood water and runoff can flow into the well, and a safety hazard because people, animals, or equipment can fall in and toxic gases can build up. Current rules prohibit them; MDH recommends upgrading with a pitless adapter. A coliform test shows whether bacteria are getting in.
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.
