Well Water Testing in Rush City

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.

Rush City is a northern Chisago County rail town of early-1900s homes near the Rush and Kettle river country. Housing here runs to early-1900s rail-town homes, across the older grid near the rail line and the newer edges.

Well water in Chisago County

MDA's 2018 township testing in Chisago County covered Amador and Sunrise townships: 382 wells were sampled and 3.7% were at or over the 10 mg/L nitrate limit, with Sunrise at 5.0% and Amador at 0.8%. That is one snapshot of two townships, so a single well can differ. MDH adds that arsenic is in groundwater statewide, found in about 40 percent of new wells drilled since 2008, and that manganese occurs naturally across Minnesota.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.
Is nitrate a concern in Chisago County wells?
MDA sampled 382 wells in Amador and Sunrise townships in 2018. About 3.7% were at or over the 10 mg/L limit: 5.0% in Sunrise and 0.8% in Amador. That is lower than several farm-heavy counties but not zero. MDH recommends nitrate testing every year and coliform bacteria every year, and a buyer should test the well itself.
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 Rush City?
Yes — the northern Chisago County town's older stock gets an experienced read on original systems, foundations and moisture.
Can you taste or smell VOCs in drinking water?
Not reliably. MDH notes that most contaminants in well water cannot be tasted, smelled, or seen, so testing is the only way to know what is in the water. Do not rely on odor to rule out a problem, particularly after a nearby fuel spill or when buying a home.
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.
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.
