Well Water Testing in Rice

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.

Rice is a small Highway 10 town of older homes and rural acreage between St. Cloud and Little Falls. Housing here runs to older homes and rural acreage, across the Highway 10 core and the acreage toward the Mississippi.

Well water in Benton County

Benton sits in central Minnesota, where MDH says the highest shares of new wells with arsenic detections are found, so a first arsenic test is worth doing on any private well. MDA's Township Testing Program sampled Langola, Maywood, Minden and Watab townships: the final dataset held 690 wells and 7.2% were at or over the 10 mg/L nitrate limit, with Langola at 14.4%. MDH also gives 100 µg/L as the safe manganese level for infant formula.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.

Buying a home with a well in Rice: 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.

The disclosure tells you a well exists, not what is in it. Add water testing to your inspection. Get a free instant quote

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.
What did the state find when it tested nitrate in Benton County wells?
MDA tested four Benton townships. Of 690 wells in the final dataset, 7.2% were at or over the 10 mg/L health limit, and township results ran from 1.6% in Maywood to 14.4% in Langola. Nitrate has no taste or smell, so MDH suggests testing every year. Your own well can differ from the township average, which is why a lab result on the specific well is what matters at purchase.
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 Rice?
Yes — the small Highway 10 town and its surrounding acreage, where wells and septic typically join the inspection scope.
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.
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.
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.
