EPA SDWIS lists three active city wells for Wilton, and they draw from two different aquifers. Wells 1 and 2, from 1968, are 450 feet deep in the Silurian aquifer; Well 4, drilled in July 2022, is 255 feet deep in buried sand and gravel, per the Iowa DNR Source Water Tracker. Well 4 produced the only published hardness figure for the system: 350 mg/L, about 20.5 grains per gallon, in a raw-water sample taken on 14 December 2022. Nothing is published for Wells 1 and 2 or the treated water, and the plant does not soften. That makes a reading at your own kitchen sink the number worth setting a softener to.
Kind Water Co is family-owned, based in Marion, Iowa, founded in 2021, and licensed and insured. On Wilton city water we fit water softeners, carbon filtration for the whole house and reverse osmosis for drinking water, and on acreages outside town we build complete well systems. We also repair and maintain the softeners, filters and RO units already in Wilton homes, including brands we did not sell. Installation is carried out by licensed local plumbing professionals we vet, schedule, and stand behind.
The free in-home water test measures hardness, iron and total dissolved solids at your kitchen sink. Bacteria, nitrate, arsenic, lead and PFAS need a certified laboratory. Travel is $1 a mile past the first 50 miles from Marion, and the mileage to your Wilton address is on your written quote before you agree to anything.

| Wilton at a glance | What the record shows |
|---|---|
| Who supplies the water | Wilton Water Supply, PWSID IA7078026, a local-government system serving 2,924 people through 1,300 service connections in EPA SDWIS. It buys no water from another system. |
| Where it comes from | Groundwater from three active wells in EPA SDWIS: Wells 1 and 2 (1968, 450 feet, Silurian aquifer) and Well 4 (2022, 255 feet, buried sand and gravel), with drill dates, depths and aquifers from the Iowa DNR Source Water Tracker. |
| Softened at the plant? | No. EPA SDWIS lists chlorination, aeration, filtration and fluoridation at the plant, and no softening objective. |
| Published hardness | One figure only: 350 mg/L (about 20.5 grains per gallon) in a raw-water sample from Well 4 on 14 December 2022, per the Iowa DNR Drinking Water Portal. None is published for Wells 1 and 2 or for treated water. |
The Census Bureau's Vintage 2024 estimate puts Wilton at 2,914 residents, all but 3 of them in Muscatine County. The city's three active wells in EPA SDWIS tap two very different formations: the Silurian aquifer at Wells 1 and 2, and buried sand and gravel at Well 4. Treated water enters the system through an entry point fed by Wells 1, 2 and 4; the federal inventory records the older entry point, which carried Wells 1 and 2 only, as inactive since 27 December 2023. The DNR tracker also lists Silurian wells drilled in 1937, 1941 and 1955 that the city no longer uses. Wilton's 2025 water quality report says Iowa DNR rated both of today's aquifers only slightly susceptible to contamination.
Iowa DNR's March 2020 sanitary survey describes the treatment in order: aeration to oxidize iron and manganese, retention, filtration to take them out, gas chlorination and fluoridation. EPA SDWIS lists chlorination, aeration, filtration and fluoridation, and no softening objective, so calcium and magnesium carry on to the tap.
Well 4 shows what the iron step is up against. Its raw water tested at 2.8 mg/L iron on 14 December 2022, about nine times EPA's 0.3 mg/L secondary standard, an aesthetic guideline rather than a health limit. No iron result is published for the treated water. Manganese was below 0.02 mg/L in a March 2020 plant sample, but that sample predates Well 4, whose raw water later read 0.03 mg/L.
Wilton disinfects with chlorine, not chloramine: the 2025 report gives a running annual average of 1.0 ppm, ranging from 0.6 to 1.4, against a 4.0 ppm limit. Sodium at the entry point was 10 mg/L on 20 November 2024, and all 17 sodium results on the state portal since 1984 fall between 9.93 and 12 mg/L. An ion-exchange softener swaps hardness for sodium, so the more hardness it takes out, the more sodium it adds.
The Iowa DNR Drinking Water Portal returns a single hardness row for Wilton: 350 mg/L as calcium carbonate, raw water from Well 4, 14 December 2022. Divided by 17.1, that is about 20.5 grains per gallon. The same sample measured 360 mg/L total dissolved solids and 32 mg/L magnesium.
There is no hardness result for Wells 1 and 2, the 450-foot Silurian wells, and none for the entry point or the distribution system. Calcium-only tests from 1984 and 1987 predate Well 4 and cannot stand in for a hardness figure.
When we queried EPA SDWIS on 13 September 2026, it returned no violations and no enforcement actions for Wilton Water Supply, and the 2025 water quality report marks every contaminant "No" for violation. Iowa DNR's 2020 sanitary survey found no significant or minor deficiencies. Each result beside its limit:
In 2024 the city began mailing service line notifications under the federal Lead and Copper Rule Revisions, and it asks residents of homes built before 1986 to report their service line material to City Hall at 563-732-2115; the 2025 report says the inventory is complete.
Every price below is all-in, covering equipment, installation, taxes and a lifetime parts warranty. The warranty covers parts for life, media for 5 years and labor for 1 year. Travel past the first 50 miles from Marion is extra, at $1 a mile.
The annual service plan is $199 a year, or $249 a year for a home with tankless RO. A diagnostic service call is $199, and a known-issue trip is $99 plus the part. Financing is available at 0% through a third-party lender with approved credit, and military and first responders get $100 off.

A private well has no treatment plant in front of it, and Wilton's own active city wells draw from two different aquifers, so a neighbor's result says little about yours. Bacteria and nitrate need a certified laboratory before any equipment goes in. Our free well water testing guide covers the options in Iowa.
Once the lab results are in, we build a complete well system around them: a dual-tank system, with sediment filtration when the readings call for it. UV at $700 is a supplemental NSF/ANSI 55 Class B unit for water that has already tested safe; it is never the fix for a contaminated well.
No hardness has been published for the water leaving Wilton's plant, and the one figure on record is a single raw sample from Well 4. We come to your home, read hardness, iron and total dissolved solids from your own tap at no charge, and leave a written all-in quote.

Only one figure is published. The Iowa DNR Drinking Water Portal holds a single hardness result for Wilton Water Supply: 350 mg/L, about 20.5 grains per gallon, in a raw-water sample from Well 4 on 14 December 2022. No hardness has been published for Wells 1 and 2 or for the treated water. Because that one number is raw water from a single well, our free in-home test reads hardness, iron and total dissolved solids from your own tap, and the softener is set to that reading.
No. EPA SDWIS lists chlorination, aeration, filtration and fluoridation at Wilton's plant, with no softening objective. Iowa DNR's 2020 sanitary survey describes the aeration and filtration as treatment for iron and manganese, followed by gas chlorination and fluoridation. Hardness is not part of that treatment, so calcium and magnesium reach the tap.
From three active city wells in two aquifers, per EPA's SDWIS facility inventory. The Iowa DNR Source Water Tracker shows Wells 1 and 2 were drilled in 1968 to 450 feet in the Silurian aquifer, and Well 4 was drilled in July 2022 to 255 feet in buried sand and gravel. The same federal inventory shows the city buys no water from another system, and Wilton's 2025 water quality report says Iowa DNR rated both aquifers only slightly susceptible to contamination.
EPA SDWIS listed no drinking-water violations and no enforcement actions for Wilton Water Supply when queried on 13 September 2026, and the 2025 water quality report marks every contaminant "No" for violation. The latest nitrate result, on 15 October 2025, was below 0.23 mg/L as nitrogen against a limit of 10 mg/L. In the 2023 lead round, the 90th percentile was 6 ppb against the 15 ppb action level; one sample was above it, and there was no violation.
Yes. Wilton's plant does not soften. A softener alone is $1,900, a whole-home softener with carbon filtration is $2,500, and adding reverse osmosis makes it $2,850, all-in. Installation is by licensed local plumbing professionals we vet, schedule, and stand behind. For a softener, filter or RO unit already in your Wilton home, of any brand, a diagnostic call is $199, or $99 plus the part for a known problem. Travel is $1 a mile past the first 50 miles from Marion, written on your quote before you agree.
