Every well that supplies the Village of Coal Valley is a deep one. The Illinois EPA source water fact sheet lists Wells 2, 3 and 5 at 555, 554 and 570 feet, all in deep bedrock, and the village’s 2025 water quality report lists sodium at 84,100 ppb, or 84.1 mg/L, from a July 16, 2024 sample. That sodium is in the water before any softener adds its own, which is worth knowing when you weigh a salt-based softener against a salt-free option.

Water softener and RO installation for Coal Valley homes

We install water softeners, whole-home filtration and reverse osmosis drinking-water systems across Coal Valley, on both the Rock Island County and Henry County sides of the village. We repair and maintain equipment you already have, including brands we did not sell, and we build well systems for acreages beyond the village mains. Installation is carried out by licensed local plumbing professionals we vet, schedule, and stand behind.

Your first appointment is a free in-home water test at the kitchen sink, measuring hardness, iron and total dissolved solids. Travel is free for the first 50 miles, $1 a mile beyond that, and quoted up front before you agree. Book the free in-home water test or get an instant quote.

A village in two counties, with a second system in its reports

Census Vintage 2024 estimates put 3,710 of Coal Valley’s 3,883 residents in Rock Island County and 173 in Henry County. The village water system is recorded under Rock Island County, but the village also posts a second 2025 report, for Oak View Estates. EPA SDWIS lists Oak View Estates (IL0730120) as a separate groundwater system in Henry County serving 95 people through 44 connections, and its report shows a single well. That report lists sodium at 109,000 ppb (October 7, 2024) and combined radium at 2.11 pCi/L (July 18, 2023). If you live in Oak View Estates, that report, not the main Coal Valley report, describes your water.

Three deep wells, two treatment setups

SDWIS records a plant for each well. The plants for Wells 2 and 3 use slat-tray aeration, pre-chlorination with gaseous chlorine and fluoridation. The plant for Well 5, which the 2025 report places south of the village at Arrowhead Ranch, about 500 feet west of 104th Street and 120th Avenue, uses cascade aeration, post-chlorination with gaseous chlorine and fluoridation. The report lists Well 2 as throttled to 260 gallons per minute and Well 3 at 280.

The other results in the 2025 report: combined radium at 2.62 pCi/L (January 29, 2024) against a limit of 5, gross alpha at 4.52 pCi/L (April 24, 2023) against 15, and fluoride at 0.78 ppm and barium at 0.244 ppm (July 16, 2024), all with no violation.

What the Coal Valley violations actually are

Since 2018, EPA SDWIS lists no maximum contaminant level violation for Coal Valley. It lists three monitoring or reporting items:

  • PCB monitoring (routine, minor): polychlorinated biphenyl samples for January 2023 to December 2025 at the Well 3 and Well 5 plants. The village’s 2025 report says this violation was an error by the Illinois EPA.
  • Nitrite monitoring (routine, major): at the Well 5 plant for October to December 2023, returned to compliance February 8, 2024.
  • Consumer confidence report adequacy: beginning July 2024, returned to compliance November 6, 2024.

Each is about sampling or reporting, not a measured exceedance.

What we install in Coal Valley, and the prices

With 84.1 mg/L of sodium already in the village water, it is worth talking through a softener versus the salt-free conditioner, which controls scale without adding salt and is for city water only. Every price is all-in: equipment, installation, taxes and a lifetime parts warranty.

  • Water softener: $2,500
  • Softener plus reverse osmosis: $2,850
  • XL softener: $2,800, or $3,150 with RO
  • Salt-free conditioner: $3,050 (city water only)
  • Reverse osmosis: $800 tank, $900 tankless
  • Well dual-tank system: $3,450, or $3,800 with tank RO
  • UV: $700, and sediment pre-filter: $500 (well only)
  • Iron and sulfur treatment: quoted after the free test

Maintenance runs $199 a year for a tank-RO home and $249 a year for a tankless-RO home. A diagnostic service call is $199; a known-issue trip is $99 plus the part. We offer 0% financing and $100 off for military and first responders. Our reverse osmosis systems are certified to NSF/ANSI 58 for total dissolved solids only, not for nitrate, PFAS, lead or radium.

Private wells and acreages near Coal Valley

A private well is not covered by the village’s testing, so the owner decides what to test. On the Rock Island County side, the Rock Island County Health Department offers water sampling and inspections for existing and new water supplies, with water testing Monday through Wednesday and prices on its fee schedule, at (309) 793-1955. On the Henry County side, contact the Henry County health department. Our free in-home test does not check for bacteria, nitrate, arsenic, lead or PFAS, which need a certified lab. For wells we install the dual-tank system; UV is a supplemental NSF/ANSI 55 Class B unit for water that has already tested safe, never the fix for a contaminated well. See well water treatment.

The village's 2025 water quality report lists sodium at 84,100 ppb, which is 84.1 mg/L, from a July 16, 2024 sample. A salt-based softener adds to that, so it is worth weighing against the $3,050 salt-free conditioner, which controls scale without salt and is for city water only.
