Le Claire shut down its own municipal utility in 2003 and has bought treated Mississippi River water ever since. The switch changed the taste at the tap — chloramines now, where well water used to be — and it moved the hardness question out of the city's hands entirely. Nobody in the chain takes the minerals out, so that job still starts at your house.
| Le Claire water at a glance | What the record shows |
|---|---|
| Water utility | Iowa American Water, Quad Cities District, PWSID IA8222001, serving 147,720 people (EPA SDWIS) |
| Water source | Mississippi River surface water, treated at East River Station |
| Softened at the plant | No. There is no softening step in any of the district's 26 SDWIS treatment records |
| Published hardness | 136 to 350 mg/L as CaCO3, which is 7.9 to 20.4 grains per gallon (Iowa American "Quad Cities 2019 Typical Water Quality Information," amwater.com/twq/) |
EPA SDWIS still carries the old record: Le Claire Utilities Department, PWSID IA8245066, serving about 2,868 people, deactivated on October 21, 2003. From that date the town's water has come from Iowa American's Quad Cities District instead of a small municipal groundwater system. The City of Le Claire's own website reflects it plainly, telling residents to take billing, service and leak questions to Iowa American rather than City Hall.
Le Claire has kept growing since. The Census Bureau's Vintage 2024 estimate puts the town at about 4,776 people, well past the 2,868 the old city utility was serving the year it shut down. That growth is a good part of why the handoff happened, and it is why so many Le Claire homes are newer builds with more bathrooms and higher flow than the plumbing the old system was designed around.
For a homeowner, that handoff swapped a small municipal well system for a surface water plant that EPA SDWIS lists as serving 147,720 people. Treatment at East River Station runs through conventional coagulation and sedimentation, a parallel Superpulsator, granular activated carbon filtration, chloramine disinfection, fluoridation, phosphate corrosion control, and an $11 million ultraviolet system added in 2022. Iowa American's own typical water quality sheet puts average output at 14.8 million gallons a day. That is 26 separate treatment records in EPA SDWIS, which is a lot of engineering standing between the river and your kitchen faucet.
Here is the part the switch did not fix. Not one of those 26 records is a softening step. And Le Claire is not unusual in that: when the EPA SDWIS treatment table is queried for every public water system in Scott County, no community water system in the county softens its water. The only softening records that come back belong to golf courses, campgrounds and mobile home parks running point-of-entry units. A town can change its source, its disinfectant and its entire treatment train, and still deliver full-hardness water to every tap.
Iowa American's "Quad Cities 2019 Typical Water Quality Information" sheet, still the live document at amwater.com/twq/, names LeClaire in its area served and lists total hardness of 136 to 350 mg/L as calcium carbonate. Converted to the unit softeners are actually sized in, that is 7.9 to 20.4 grains per gallon. The U.S. Geological Survey classifies anything above 180 mg/L as very hard, so the top of Le Claire's published range sits well inside that band.
That spread matters more than the average. River water moves with the season, so a home in Le Claire can be dealing with roughly eight grains one month and twenty the next. Eight grains is already enough for spotted glassware, filmy shower doors, stiff towels and scale building quietly inside a water heater. Twenty grains is a different job entirely, and a softener sized for the low end of that range will run short of capacity when the river swings the other way. It is also why we do not size anything in Le Claire off a published sheet alone.
Well water and river water do not taste the same, and they are not disinfected the same way. The Quad Cities plant uses chloramines rather than free chlorine, alongside granular activated carbon filtration for taste and odor. Most homeowners never think about it, but some notice a faint chemical edge in a glass of cold tap water or in coffee. That is an aesthetic issue, not a compliance one, and it is exactly what a carbon block or a reverse osmosis drinking water system is built to handle at the point you actually drink from.
Every price below is one all-in number: equipment, installation, taxes, and a lifetime parts warranty. Our softeners are built from NSF/ANSI 44 certified components and our reverse osmosis systems are certified to NSF/ANSI 58.
0% financing is available, and we take $100 off for military members and first responders.
Le Claire's market is genuinely split. The city itself is on river water, but several active private community systems still ring the town, including Vista Hills, River Highlands, McCarty Creek HOA #8, Woods and Meadows, Trout Valley and Napsinekee Heights. Per the Iowa DNR Source Water Protection Tracker, Scott County's independent systems draw from Silurian dolomite wells, roughly 100 to 490 feet deep, rather than the deeper Jordan aquifer. None of them soften either.
If you are on your own private well instead, the Iowa DNR recommends testing it once a year, and Iowa's Private Well Grants program covers county lab testing at no cost to the homeowner. Our guide to free well water testing in Iowa walks through how to arrange it.
Well chemistry is its own project. Our well water treatment builds start with a dual-tank system at $3,450, or $3,800 with a tank RO. UV disinfection adds $700 and sediment pre-filtration $500, both well-only. Iron and sulfur treatment is quoted after your free water test, because guessing at it does nobody any favors.
Kind Water Co is licensed and insured. Installations are performed by licensed local plumbing professionals we vet, schedule, and stand behind, so you are not left coordinating between a salesperson and a stranger.
We quote one all-in number, published on the page, so nothing shows up on the invoice that was not in the quote. The warranty is lifetime on parts, five years on media and one year on labor, and it comes with the system rather than being sold to you afterward. And we size to your actual water and your actual household, which in Le Claire means sizing for the top of that 20.4 grain range, not the average of it.
A published range of 7.9 to 20.4 grains is a starting point, not an answer. We test at your tap, walk you through what the numbers mean, and give you a firm quote with no pressure. Call 319-319-6566 or email ryan@kindwaterco.com to book your free in-home water test.
We install throughout the Iowa Quad Cities. See our Quad Cities water treatment overview, or the pages for Bettendorf, Davenport, Park View and Princeton.
Growth is a good part of it. The Le Claire Utilities Department, PWSID IA8245066, was serving about 2,868 people when EPA SDWIS shows it deactivated on October 21, 2003, and the Census Bureau now puts the town at about 4,776. A small municipal well system handed off to Iowa American's Quad Cities District, which serves 147,720 people.
Yes. Iowa American's Quad Cities 2019 Typical Water Quality sheet, which names LeClaire in its area served, publishes total hardness of 136 to 350 mg/L as calcium carbonate, or 7.9 to 20.4 grains per gallon. The upper end is classed very hard by the U.S. Geological Survey. That range is wide because river hardness shifts with the season.
Yes. The 2003 switch changed the source, not the hardness. None of the 26 EPA SDWIS treatment records for the Quad Cities District includes a softening step, so full-hardness water still reaches your tap at 7.9 to 20.4 grains per gallon. We size for the top of that range after a free in-home water test.
The 2003 switch changed both the source and the disinfectant. The Quad Cities plant treats Mississippi River water and disinfects with chloramines rather than free chlorine, with granular activated carbon filtration for taste and odor. Some homeowners still notice a faint chemical edge. That is an aesthetic issue, and a carbon filter or reverse osmosis system addresses it at the drinking tap.
Kind Water Co installs a whole-home softener in Le Claire for $2,500 all in, covering equipment, installation, taxes and a lifetime parts warranty. A softener paired with reverse osmosis is $2,850, and the XL softener for larger homes is $2,800, or $3,150 with RO. 0% financing is available, and military members and first responders save $100.
