Reynolds gets its water from deep underground. The village's two wells are 650 and 641 feet deep, both listed by the Illinois EPA as deep bedrock wells, and the village alternates which one serves as the main well every month. What comes up is hard rather than very hard: an October 20, 2024 sample of finished water measured 160 mg/L total hardness, about 9.3 grains per gallon, along with 140 mg/L of sodium and 410 mg/L of total dissolved solids.
If you are hiring for water treatment in Reynolds, here is what Kind Water Co does. We install whole-home water softeners, whole-home filtration and reverse osmosis systems for drinking water, and we repair and maintain what you already own, even when a different company or brand put it in. For farms and acreages on their own wells, we design and build complete well systems. Your installation is handled by licensed local plumbing professionals we vet, schedule, and stand behind.
We begin with a free in-home water test that measures hardness, iron and total dissolved solids at your kitchen sink, which matters in Reynolds, where dissolved solids are part of the story and not just hardness. The first 50 miles of travel are free; beyond that we charge $1 a mile and quote it before you agree. Book the free in-home water test or try the instant quote to see numbers first.
| Reynolds at a glance | What the record shows |
|---|---|
| Who supplies the water | Village of Reynolds community water system, IL1614800, serving 508 people through 259 service connections (EPA SDWIS) |
| Where it comes from | Two deep bedrock wells, 650 and 641 feet deep, alternated monthly (Illinois EPA source water assessment); no purchased water on record |
| Softened at the plant? | No. The treatment on record is aeration, fluoridation and chlorination |
| Published hardness | 160 mg/L (9.3 gpg) in finished water, October 20, 2024 (Illinois EPA sample record) |
The Reynolds record is about more than hardness. The October 2024 finished-water sample showed 160 mg/L hardness alongside 140 mg/L sodium, 380 mg/L alkalinity and 410 mg/L total dissolved solids. A raw sample taken straight from Well 1 on January 22, 2026 looked much the same: 145 mg/L hardness (about 8.5 grains per gallon), 132 mg/L sodium and 484 mg/L total dissolved solids. Iron was barely present, at 0.044 mg/L after treatment and below the laboratory's reporting limit in the raw well sample.
For a homeowner, that shapes the conversation. At about 9.3 grains per gallon the water sits in the U.S. Geological Survey's hard range of 121 to 180 mg/L, and a softener is how you remove that hardness at the house. A salt-based softener exchanges hardness minerals for sodium, and this water already contains sodium, so it is worth talking through at the free test. For drinking water you can pair softening with a reverse osmosis system at the kitchen sink; our units are certified to NSF/ANSI 58 for total dissolved solids reduction. EPA's non-enforceable secondary guideline for total dissolved solids is 500 mg/L, and the October 2024 finished-water sample came in at 410. Our reverse osmosis guide covers how the systems work.
Illinois EPA's source water assessment found the Reynolds supply not susceptible to contamination, based on monitoring at the wells, monitoring where water enters the distribution system, and available hydrogeologic data on the wells. The recent lab record lines up with that: a November 17, 2025 nitrate sample from the treatment plant came back below the laboratory's reporting limit of 0.03 mg/L. EPA's SDWIS database shows no violations of any kind for the Reynolds system since a 2011 consumer confidence report violation that was resolved the same month.
Most of Reynolds sits in Rock Island County, but the village boundary crosses into Mercer County. Census Vintage 2024 estimates put 457 of the village's 488 residents on the Rock Island County side and 31 in Mercer County. EPA lists the village water system as serving Rock Island County. The county line matters most for private wells, because which health department issues permits and takes samples depends on where your property sits.
On village water in Reynolds, a common build is a water softener built from NSF/ANSI 44 certified components, with reverse osmosis at the kitchen sink if you want lower dissolved solids in your drinking water. On a rural well, the well dual-tank system is designed for that job. All prices are all-in, including 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. If you already have a softener that needs attention, we service that too.
Village lab results cover village water only. On a rural property with its own well, testing is up to you, and the right office depends on the county. On the Rock Island County side, the Rock Island County Health Department issues well permits for $150, including an inspection and a sample, and takes water samples Monday through Wednesday. Its 2022 fee schedule lists coliform bacteria at $40 and coliform plus nitrates at $80. Call (309) 793-1955. If your property is on the Mercer County side, call the Mercer County Health Department in Aledo at (309) 582-3759 and ask about private well sampling there.
Bacteria and nitrate results from a certified lab come first, since our free in-home test does not check bacteria, nitrate, arsenic, lead or PFAS. After that we add hardness, iron and dissolved solids and design the well system around all of it: a dual-tank setup, sediment pre-filtration, and UV where it fits. The UV we install is certified to NSF/ANSI 55 Class B, meaning supplemental treatment for water that has already tested safe, not a fix for a contaminated well.
We will test your Reynolds water for hardness, iron and total dissolved solids at the kitchen sink and explain the results in plain language before recommending anything. Schedule your free in-home water test, or run the instant quote first if you want a price range in hand.

Hard. A finished-water sample from the village treatment plant on October 20, 2024 measured 160 mg/L total hardness, about 9.3 grains per gallon. The U.S. Geological Survey classes 121 to 180 mg/L as hard.
Yes. The same October 2024 sample measured 140 mg/L sodium, and a January 2026 sample from Well 1 measured 132 mg/L. A salt-based softener exchanges hardness minerals for sodium, so we go over those numbers with you at the free in-home test before recommending a system.
From two village wells drilled 650 and 641 feet into deep bedrock, which the village alternates monthly. EPA's records show no purchased water, and the plant aerates, fluoridates and chlorinates the water without softening it.
Installation is done by licensed local plumbing professionals we vet, schedule, and stand behind. We also repair and maintain softeners, filters and reverse osmosis systems we did not sell. A diagnostic service call is $199.
Call the Mercer County Health Department in Aledo at (309) 582-3759 and ask about private well sampling there. On the Rock Island County side, the Rock Island County Health Department takes water samples Monday through Wednesday. Our free in-home test does not check bacteria or nitrate, so start with a certified lab.
