Well Water Testing in Little Canada

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.

Little Canada is a second-ring suburb founded by French-Canadian settlers in 1844, on Lake Gervais and I-35E. Housing here runs to mostly postwar houses from the years after it became a village in 1953, with some older farmhouses, newer townhomes and apartments, across the Lake Gervais east side, the I-35E and I-694 corridors.

Well water in Ramsey County

MDA's township testing schedule lists no Ramsey County report, so there is no county nitrate percentage to quote. Private wells in the county are not covered by any MDA township sample, which means a well's quality is known only from its own test. MDH recommends that private well owners test for coliform bacteria every year, nitrate every year, and arsenic and lead at least once, using an accredited laboratory. A dated lab report is the only reliable way to know what is in a specific well.

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.

Wells built before 1974, when Minnesota's well code began, are listed by MDH as higher risk for bacteria, along with leaking dug wells, wells in old frost pits and wells with corroded casings.

Buying a home with a well in Little Canada: 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.
Is there county nitrate data for private wells in Ramsey County?
No. MDA's township testing schedule lists no Ramsey County report, so there is no county nitrate rate to quote. For a private well, the useful number is your own result. MDH recommends an accredited laboratory, with coliform checked yearly, nitrate every year, and arsenic and lead 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.
Little Canada has French-Canadian roots. Are there older houses from that era?
The area began with Benjamin Gervais, who moved north from St. Paul in 1844 and built the first grist mill in Minnesota that was independent of the government. The township was organized as New Canada in 1858 and became a village in 1953, partly to keep neighboring cities from absorbing it. Few houses will trace back to the earliest settlement, so we date each house individually, checking original plumbing, aging roofs and furnaces, and basements near Lake Gervais and low ground. Ramsey County is EPA Radon Zone 1.
Is there a safe limit for DRO in drinking water?
DRO has no health limit of its own. MPCA guidance says DRO and GRO results are not used to assess human health risks. Instead, specific chemicals such as VOCs and PAHs are compared with MDH human-health-based water guidance values. Ask your lab and MPCA how to interpret a result.
How often should I test my well for coliform bacteria in Minnesota?
MDH recommends testing private wells for coliform bacteria every year. It also recommends testing after any well work and after any change in the water's taste, smell, or appearance. Use an accredited laboratory, which can provide a sample container and instructions for collecting the sample.
How far must a well be from a lake, stream, or pond?
The minimum horizontal distance between a water-supply well and the ordinary high water level of a stream, river, pond, stormwater retention pond, or lake is 35 feet (Minnesota Rules 4725.4350). The distance does not apply to areas protected by a FEMA-accepted flood control structure, to wetlands, ditches, or depressions holding water under six months a year, or to artificial ponds under 5,000 gallons. If the wellhead is close to surface water, a coliform test is a reasonable check of how the water is holding up.
How can I tell if there is a forgotten well on my property?
The Department of Health suggests looking for a pipe 1 to 8 inches wide at, above, or below the surface, a low spot or sunken area, a metal, wood, or concrete cover, a windmill or old well house, and a concrete patch or glass block in a basement step or floor. Well pits and basement offsets are other common signs. Visible signs like these are worth raising with your agent and a licensed well contractor.
