Eldridge runs the largest independent municipal water system in Scott County — four city wells drilled 462 to 487 feet into the Silurian dolomite, treated at Eldridge's own plant. That plant removes iron. It does not soften. Whatever hardness those wells carry arrives at your tap, and the city publishes no figure for it.

Eldridge does not buy its water from anybody. The Iowa DNR Source Water Protection Tracker lists four active municipal wells for PWSID 8230008, all drilled into the Silurian dolomite at 462 to 487 feet, and the city's 2025 report samples them together as Wells #2 through #5. That is the largest independent municipal system in the county, on its biggest Silurian well field — while most of the metro drinks Mississippi River water piped in by Iowa American.
It is a good source, and the city says so in its own report: the Iowa DNR's source water assessment found the Silurian aquifer here slightly susceptible to contamination, because the aquifer and the material above it give moderate protection from anything at the land surface.
Deep dolomite has one predictable side effect, though. Water moving through it dissolves calcium and magnesium, and that is exactly what hardness is — scale on the kettle, film on the shower door, the extra scoop of detergent. It is an aesthetic and plumbing-wear problem rather than a safety one, and it is fixable inside your own house.
This is the part homeowners most often get wrong. Eldridge does run a real treatment plant, and it does a real job. EPA SDWIS lists thirteen treatment records for it: cascade and forced-draft aeration with gravity, sand and anthracite filtration under the iron-removal objective, gaseous chlorination, caustic soda for pH, and fluoridation. Not one is a softening record. An iron-removal plant and a softener are different machines solving different problems, and the city has not claimed otherwise.
Eldridge is not unusual here either. Checked against the EPA SDWIS treatment table, not one community water system in Scott County softens its water — the only softening records in the county belong to golf courses, campgrounds and mobile-home parks on point-of-entry units. Davenport and Bettendorf on river water, Walcott and Buffalo on their own wells, Eldridge on its well field: all of it arrives at full hardness. Softening in Scott County happens in basements, or not at all.
We are not going to hand you a grains-per-gallon figure for Eldridge, because the city does not publish one. Hardness has no EPA limit, so it is not a required line in a Consumer Confidence Report, and the 2025 report does not include it.
We are also not going to borrow a neighbor's number. The published hardness figures that do exist in Scott County belong to other systems on other water — Iowa American's river supply on one side of the county, Princeton's own wells on the other — and none of them describe a tap in Eldridge. Guessing from a town ten miles away is how people end up sized wrong in both directions: too small for a busy house, or too much softener burning salt for no reason.
The fix is unglamorous and free. We test at your kitchen sink, on your water, and size the system to that number. About twenty minutes, no charge, no obligation.
Eldridge's 2025 Consumer Confidence Report, dated March 12, 2026, is worth reading, and we would rather walk you through it. On lead, the 90th-percentile result was 1.30 ppb against an action level of 15 ppb, range not-detected to 2 ppb. On copper, the 90th-percentile result was 0.73 ppm against an action level of 1.3 ppm, range 0.022 to 1.4 ppm, and the report notes that one sample exceeded the action level. The city records no violation for either result.
Under "Other Violations," the same report discloses that in July 2025 the city had a "Notification, Known Or Potential LSL" violation under the Lead and Copper Rule Revisions — a notification requirement tied to service line inventory, not a contaminant level. EPA SDWIS separately logs one Lead and Copper Rule monitoring and reporting violation, compliance period beginning June 1, 2023, flagged as not health-based and returned to compliance on November 18, 2024. The city reports its service line inventory is now complete.
Lead and copper results depend heavily on the plumbing in the house sampled, which is why these samples are collected at kitchen taps rather than at the plant. Questions about your own service line belong with Eldridge Water Supply, which holds the inventory. The rest of the 2025 report is quiet: chlorine at a 2.9 ppm running annual average, trihalomethanes at 17 ppb against an 80 ppb limit, haloacetic acids at 14 ppb against 60, barium 0.41 ppm, sodium 11 ppm and fluoride at 0.62 ppm — each inside its limit.
Eldridge is on city water, so the whole product line is open to you. Every price below is all-in — equipment, installation by licensed local plumbing professionals we vet, schedule and stand behind, taxes, and a lifetime parts warranty.
Iron and sulfur treatment is quoted after your free water test, because the right answer depends on the numbers that come back. Financing is available at 0%, and military and first responders take $100 off.
Plenty of households in the countryside around Eldridge — out toward Donahue, McCausland and the farms between — are not on city water. They draw from their own wells in the same Silurian dolomite, with nobody sampling it for them and no annual report in the mail. For those homes we build a well package: dual-tank softener at $3,450, or $3,800 with a tank RO, plus UV at $700 and sediment prefiltration at $500 where the test calls for them. Start with the free well water test.
Kind Water Co is licensed and insured. Our softeners are built from NSF/ANSI 44 certified components and our reverse osmosis systems are certified to NSF/ANSI 58. Our prices are posted publicly and all-in, with the install and the taxes already inside the number, so the figure you read here is the figure on the invoice. We are an Eastern Iowa company, and we know the difference between Mississippi River water in Davenport and deep Silurian well water in Eldridge — so we would rather test yours than sell the same box to every address on the street.
Twenty minutes at your kitchen sink, real numbers for your own house, and a written all-in price before anyone touches a pipe. Get an instant quote, or book the test and we will come to you.

No. Eldridge Water Supply runs an iron-removal plant, not a softener. EPA SDWIS lists thirteen treatment records for the plant — cascade and forced-draft aeration with sand and anthracite filtration for iron, chlorination, caustic soda for pH, and fluoridation — and no softening record at all. In Eldridge, softening happens in the home.
No. Aeration and sand-and-anthracite filtration are there to take iron out; they leave the dissolved calcium and magnesium alone, so hardness arrives at your tap at full strength. Eldridge publishes no hardness figure either, since hardness is unregulated and the 2025 report does not list one. Rather than borrow a neighboring town's number, we measure yours at your kitchen sink, free.
From its own wells. The Iowa DNR Source Water Protection Tracker lists four active municipal wells for PWSID 8230008, drilled into the Silurian dolomite aquifer at 462 to 487 feet. It is the largest independent municipal system in Scott County, and the DNR's source water assessment found the aquifer beneath it slightly susceptible to contamination.
Lead came in at a 90th percentile of 1.30 ppb against an action level of 15, range not-detected to 2. Copper came in at 0.73 ppm against an action level of 1.3, range 0.022 to 1.4, with one sample above the action level. No violation is recorded for either. Tap results reflect individual home plumbing; service line questions go to Eldridge Water Supply.
A standard softener is $2,500 installed, or $2,850 paired with a reverse osmosis drinking water system. The XL softener is $2,800, or $3,150 with RO. Every price includes equipment, installation by licensed local plumbing professionals we vet, schedule and stand behind, taxes and a lifetime parts warranty. Financing is 0%, and military and first responders take $100 off.
