Well Water Testing in Grasston

Well water testing for homes on a private well across Minnesota. We collect the sample the right way and send it to an accredited laboratory for coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, iron, hardness, pH, fluoride, sulfate and uranium. The Minnesota Department of Health recommends testing a private well for coliform bacteria every year, nitrate every other year, and arsenic and lead at least once. We also look at the visible wellhead, the pressure tank and the water treatment equipment during the home inspection.

Grasston is a Kanabec County village on Grass Lake, with a post office since 1899. Housing here runs to early-1900s village houses, some mid-century farmhouses, and a few newer homes, on lots that mostly run on wells and septic, across the village blocks by Grass Lake and the farm ground along Highways 70 and 107.

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 other year, and arsenic and lead at least once. We test those plus manganese, iron, hardness, pH, fluoride, sulfate and uranium through an accredited lab.

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 do you test for?
Our lab panel covers coliform bacteria and E. coli, nitrate, arsenic, lead, manganese, 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. 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 other 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. Book it with the home inspection and we collect the sample the same visit, so the lab results arrive with time to act on them inside your inspection window.
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. We run nitrate and arsenic on the same accredited report. The lab report also covers lead, manganese and iron, so one sample answers several buyer questions.
Grasston peaked at 239 people in 1920 — how does that show up in its houses?
It shows up as age. A post office has served Grasston since 1899, and the village peaked at 239 residents in 1920, then slid to about 105 by 2000 before recovering to about 154 in 2020. That leaves a mix of century-old houses, some sitting quiet for years, and newer replacements. We look for unheated winters in old plumbing, rodent entry, old knob-and-tube or patched wiring, worn roofs and sagging porch framing. Wells and private septic are common in small Kanabec County towns, so we ask for records and check the systems that are visible.
