Well Water Testing in Quamba

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.

Quamba is a Kanabec County Great Northern siding town, the only Minnesota city starting with Q. Housing here runs to early-1900s railroad-siding houses, mid-century homes and a few newer builds, many on wells and septic, across the small townsite along Mud Creek and the farm and woods acreages of northern Kanabec County.

Well water in Kanabec County

MDA's 2018 township testing in Kanabec County covered Southfork Township, where 115 wells were tested and 4.3% were over the 10 mg/L nitrate-nitrogen health standard. It is one township, so use it as a hint, not a rule. MDH says arsenic is elevated in central and west-central Minnesota and can swing between neighboring wells, and lists coliform yearly, nitrate every year, and arsenic and lead at least once.

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.
What did MDA find in Kanabec County wells?
In Southfork Township's 2018 testing, 4.3% of 115 wells were over the 10 mg/L nitrate health standard. That is one township. Because arsenic can vary between nearby wells, MDH advises testing for it at least once. MDH also recommends testing for 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.
Quamba was once called Mud Creek — does that affect houses?
It is a clue to check drainage. The community began as Mud Creek on a Great Northern sidetrack in 1882, was platted in 1901 and incorporated as a village in 1952, and its name is said to come from a word meaning muddy hole. Low ground here can hold water after thaw and storms. Grading, sump and basement moisture, sill and rim-joist condition, and private well and septic systems are the things to watch. It is the only Minnesota city starting with Q, but the inspection is standard.
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.
Does boiling water remove nitrate?
No. MDH warns that boiling makes nitrate more concentrated because water evaporates and the nitrate stays behind. If your well is above 10 mg/L, use bottled water or another safe alternative for drinking and for infant formula, and have a licensed well contractor inspect the well.
What is a pitless adapter?
A pitless adapter or pitless unit is a fitting attached to the well casing below ground, usually 6 or 7 feet down, that sends water to the building through a buried service line below the frost line. The casing extends above ground and carries the well cap. Minnesota Rules 4725.4850 governs connections made less than 12 inches above ground. It is the reason a modern well needs no pit; its presence and the cap above it can be noted at a visual check.
Does the well disclosure apply to sand-point and dug wells too?
Yes. The Minnesota Department of Health says the disclosure law covers all types of wells, whether used for drinking water, irrigation, livestock, heating or cooling, or monitoring. That includes drive-point (sand-point) wells, drilled wells, and dug wells. The law is Minnesota Statutes section 103I.235, part of the Ground Water Protection Act. Ask for the disclosure early, then have the in-use well tested before closing.
