Oak Grove has no village water system on the public record. Illinois EPA's Drinking Water Watch list of Rock Island County water systems and EPA's national SDWIS database show no community water supply run by the Village of Oak Grove. The only Rock Island County system carrying the Oak Grove name is a privately owned mobile home park with 55 service connections. We could not find a public record showing how the rest of the village's homes get their water, so the most useful number for an Oak Grove home is the one you measure yourself.
Kind Water Co installs whole-home water softeners, whole-home filtration and reverse osmosis drinking-water systems, and we repair and maintain existing equipment, including brands we did not sell. For homes and acreages on private wells, we build complete well systems. The work is carried out by licensed local plumbing professionals we vet, schedule, and stand behind.
Because there is no utility report to lean on in Oak Grove, the free in-home water test does the heavy lifting. We measure hardness, iron and total dissolved solids at your kitchen sink. Travel costs nothing for the first 50 miles, then $1 a mile, and we quote it before you agree. Start by booking the free in-home water test, or check the instant quote.

Oak Grove MHP - Rock Island County (IL1617785) is a privately owned community water system serving 138 people through 55 connections from a single well, 451 feet deep in bedrock according to Illinois EPA's source water assessment. That assessment lists the Village of Oak Grove about 1,000 feet from the park's well, along with a second park, Woodland A and B MHP, which is its own private system (IL1617925) serving 490 people through 245 connections. EPA lists both as mobile home park service areas. Neither is operated by the village.
The Oak Grove park's well does have a lab record. An Illinois EPA sample record from November 6, 2023 measured 250 mg/L hardness, about 14.6 grains per gallon, with 420 mg/L total dissolved solids, 69 mg/L sodium and almost no iron. A July 6, 2026 nitrate sample was below the reporting limit. Those numbers describe that one 451-foot well. They say nothing reliable about a private well elsewhere in the village, which may be drilled to a different depth.
EPA's database lists three items for the park system since 2018, and none is a contaminant-limit violation: a missed chlorine monitoring period in early 2024, resolved that February; a consumer confidence report violation beginning July 2025; and a lead and copper tap monitoring violation beginning October 2025. The last two are still listed as open.
With no village report, there is no published hardness, iron or nitrate figure for an Oak Grove home, and we will not borrow one from a neighboring town. The order of operations is simple. First, a certified lab test for coliform bacteria and nitrate, because our free in-home test does not check bacteria, nitrate, arsenic, lead or PFAS. Second, our free in-home test for hardness, iron and total dissolved solids. With both results in hand, choosing equipment stops being guesswork.
If your Oak Grove home is on a private well, the well dual-tank system is built for that. If you are on a park system or other public supply, a standard water softener built from NSF/ANSI 44 certified components applies, and reverse osmosis can be added at the kitchen sink. Every price is all-in, covering equipment, installation, taxes and a lifetime parts warranty:
Maintenance is $199 a year for a home with a tank RO and $249 a year for a home with a tankless RO. A diagnostic service call is $199, and a trip for a known issue is $99 plus the part. We offer 0% financing, and military members and first responders get $100 off. Softener already installed and misbehaving? Start with our softener repair guide.
The Rock Island County Health Department is the local office for private water supplies. It takes water samples Monday through Wednesday, and its 2022 fee schedule lists coliform bacteria at $40, coliform and nitrates at $80, nitrates only at $40, and nitrates and nitrites at $60, each $20 more with pick-up. Well permits are $150, including an inspection and a sample. The department is at 2112 25th Ave. in Rock Island, (309) 793-1955.
If a well tests positive for bacteria, deal with that first. The UV unit we install is certified to NSF/ANSI 55 Class B, meaning supplemental treatment for water that has already tested safe. It is not a cure for a contaminated well.
An Oak Grove home without a utility report is exactly where a test pays off. We will measure hardness, iron and total dissolved solids at your kitchen sink and tell you what the results mean, with no obligation. Book your free in-home water test or get an instant quote.
