Rapids City’s water comes from two village wells, each rated at 250 gallons per minute in the village’s 2025 water quality report — and every violation that report lists is a missed test or a reporting problem, not a contaminant over its limit. The 2025 radium and gross alpha samples were collected, the village explains, but the lab never received the bottles.
We install water softeners, whole-home filtration and reverse osmosis drinking-water systems in Rapids City, and we take on repair and maintenance for equipment that is already there, including brands we did not sell. For acreages on private wells, we build full well systems. Installation is handled by licensed local plumbing professionals we vet, schedule, and stand behind.
Before recommending anything, we run a free in-home water test at your kitchen sink for hardness, iron and total dissolved solids. The first 50 miles of travel are free, then it is $1 a mile, quoted before you agree. Book the free in-home water test or try the instant quote. If a drinking-water system is what you are weighing, our reverse osmosis guide for the Quad Cities explains what RO does and does not do.
| Rapids City at a glance | What the record shows |
|---|---|
| Who supplies the water | The Village of Rapids City, PWSID IL1610600; EPA SDWIS lists 962 people served and 440 service connections |
| Where it comes from | Groundwater from Well 1 and Well 2, treated at one plant; the 2025 report says the wells are constructed in a confined aquifer |
| Softened at the plant? | No. EPA SDWIS lists five treatment records for the well treatment plant, and none carries a softening objective |
| Published hardness | None published. The 2025 water quality report prints no hardness figure |
The 2025 report places Well 1 at 730 17th Street and Well 2 about 500 feet north of the treatment plant, next to the elevated tank; both are listed as active groundwater sources at 250 gallons per minute. EPA’s facility record shows both wells feeding a single treatment point, a 150,000-gallon elevated tank in service, and the older distribution elevated and ground storage records deactivated on June 4, 2025.
Quoting the Illinois EPA source water assessment, the report says the wells are constructed in a confined aquifer, the source water is not considered susceptible to contamination, and the supply is not vulnerable to viral contamination.
Four violations appear in the 2025 report, and every one falls in the monitoring or reporting category. Chlorine monitoring for June 2025 was recorded as missed; the village’s notice says the test was run on time with passing results and that a page of the lab paperwork did not reach, or was not opened by, Illinois EPA. Gross alpha and combined radium monitoring for 2025 was missed because the bottles never reached the lab; the notice gives February 9, 2026 as the follow-up sampling date, and Illinois EPA marked both returned to compliance on March 6, 2026. The fourth is a Consumer Confidence Rule adequacy violation opened July 1, 2025.
The only other violation since 2018 is a 2020 Lead and Copper Rule consumer-notice item, returned to compliance on January 20, 2021. None of these records a contaminant above its limit.
Combined radium 226/228 measured 2.44 pCi/L in a February 15, 2024 sample, under the 5 pCi/L limit. An August 20, 2024 sample put sodium at 24.3 mg/L, iron at 0.114 ppm against Illinois’s 1.0 ppm limit, fluoride at 0.69 ppm and barium at 0.499 ppm. Total trihalomethanes were 5 ppb in 2025, against an 80 ppb limit.
The report lists the lead tap-sampling range as not detected to not detected. For copper, the September 26, 2023 round shows a 90th percentile of 1.13 ppm, under the 1.3 ppm action level, with one site above it, and the report gives the copper range as 65.2 to 2,030 µg/L; the likely sources listed are corrosion of household plumbing and erosion of natural deposits. Our reverse osmosis systems are certified to NSF/ANSI 58 for total dissolved solids only, not for radium or lead.
These are complete prices — equipment, installation, taxes and a lifetime parts warranty — whether you are on village water or on a well outside town.
Maintenance is $199 a year for a tank-RO home and $249 a year for a tankless-RO home. A diagnostic service call is $199, and a known-issue trip is $99 plus the part. Financing is available at 0%, and military and first responders get $100 off. Read more on water softeners, reverse osmosis drinking water and well water treatment.

The village record describes Rapids City’s two public wells; a private well on a nearby acreage is a separate water supply, and its testing falls to the owner. The Rock Island County Health Department offers water sampling and inspections for existing and new water supplies. Its water testing is available Monday through Wednesday, with fees set by the department’s fee schedule, and it handles Illinois water well permits and well sealing applications. Reach it at (309) 793-1955 or 2112 25th Ave., Rock Island.
Bacteria, nitrate, arsenic, lead and PFAS need a certified laboratory, so ask the health department which tests it runs. Our free in-home test does not cover those. Once a well has tested safe, we build the equipment side of a well water system: the dual-tank setup, a sediment pre-filter and, where it fits, a supplemental UV unit.
Rapids City’s report gives you radium, sodium and copper, but not hardness. We measure hardness, iron and total dissolved solids at your kitchen sink, go over the results with you, and size a system only if the numbers call for one. Book the free in-home water test, or begin with an instant quote.

From two village wells, Well 1 and Well 2, each listed at 250 gallons per minute in the 2025 water quality report and treated at one treatment plant. The report says the wells are constructed in a confined aquifer, and EPA SDWIS lists 962 people served under PWSID IL1610600.
All were monitoring or reporting violations: missed chlorine monitoring for June 2025, missed gross alpha and combined radium monitoring for 2025 after the sample bottles never reached the lab, and a Consumer Confidence Rule adequacy violation. Illinois EPA marked the radium and gross alpha items returned to compliance on March 6, 2026. None records a contaminant above its limit.
The 2025 report lists combined radium 226/228 at 2.44 pCi/L from a February 15, 2024 sample, under the 5 pCi/L limit, with no violation. Our reverse osmosis systems are certified to NSF/ANSI 58 for total dissolved solids only and are not certified for radium, so radium questions belong with a certified lab.
Yes. Reverse osmosis is $800 with a tank or $900 tankless, all-in, installed by licensed local plumbing professionals we vet, schedule, and stand behind. Maintenance plans are $199 a year for a tank-RO home and $249 for a tankless-RO home, and we service existing systems, including brands we did not sell.
No hardness figure is published. The 2025 water quality report does not print one, and EPA SDWIS lists no softening step at the well treatment plant. Our free in-home test measures hardness, iron and total dissolved solids at your kitchen sink.
Every number on this page comes from a public record. Here is where to open each one yourself.
