Kind Water Co installs water softeners, reverse osmosis drinking water systems, and whole-home filtration in Epworth, Iowa. Epworth runs a groundwater system, and its 2025 water quality report lists nitrate measured up to 8.3 ppm against the 10 ppm federal limit — the kind of number that makes reverse osmosis at the kitchen sink worth a conversation here.
| Quick fact | Details |
|---|---|
| Utility | Epworth Water Supply (PWSID 3133033), City of Epworth |
| Water source | Groundwater. Iowa DNR lists Epworth as a community groundwater system with Well #2 (1964), Well #3 (1978) and Well #4 (1978), plus three treatment plants |
| Softened at the plant? | No municipal softening is described in the 2025 report, and no hardness figure is published. Sodium is listed at 41.1 and 39.3 ppm with treatment-added sodium noted |
| One distinguishing fact | The 2025 report lists nitrate at up to 8.3 ppm (range 5.4–8.3) at the finished-water tap #3, against a 10 ppm maximum contaminant level — no violation, but the highest nitrate we found in this group of Dubuque County towns |
Epworth's system is straightforward: three wells drilled between 1964 and 1978, three treatment plants, groundwater from start to finish, all documented in the Iowa DNR facility record. The city posts its consumer confidence report on epworthiowa.org.
The number that stands out in the 2025 report is nitrate: measured up to 8.3 ppm, with a range of 5.4 to 8.3, against the EPA's 10 ppm maximum contaminant level. That is under the limit, and Epworth reported no violation for the year — we are quoting the city's own document, not raising an alarm. But it is a real, verifiable figure, and it is higher than the neighboring systems we surveyed, so it is worth knowing what it means practically.
Iowa State University's extension materials note that nitrate is odorless and tasteless — you cannot detect it at the tap — and that the technologies that actually remove it are reverse osmosis, distillation, and anion exchange. The CDC makes the same point from the other direction: boiling does not remove chemical contaminants, and with nitrate, boiling concentrates it as water evaporates. A carbon pitcher filter does not touch it either. If nitrate is what you care about in Epworth, an under-sink RO system is the practical answer, and it is the least expensive thing we install. Our nitrates in Iowa water page goes deeper.
The 2025 report also lists sodium at 41.1 and 39.3 ppm — noted as both naturally occurring and added during treatment — along with detections of selenium and barium. No hardness figure is published, so we do not quote one for Epworth; we measure it at your sink instead.

If you are outside the Epworth system on your own well, nobody publishes a report for you — and nitrate is exactly the contaminant that private wells in row-crop country need watched. The Iowa DNR recommends annual testing for bacteria and nitrate, and Iowa's Private Well Grants program covers free county lab testing through your county environmental health office. Dubuque County wells also commonly show iron staining and hardness.

Yes, and the city publishes the number. Epworth's 2025 water quality report lists nitrate measured up to 8.3 ppm, with a range of 5.4 to 8.3, against the EPA's 10 ppm maximum contaminant level. The city reported no violation. If you want it out of your drinking water, reverse osmosis is the standard method.
No. The CDC is explicit that boiling does not remove chemical contaminants — and with nitrate, boiling concentrates it as water evaporates. Iowa State University extension materials list reverse osmosis, distillation and anion exchange as the technologies that actually remove nitrate. A standard carbon pitcher filter does not remove it either.
No municipal softening is described in the city's 2025 report, and no hardness figure is published, so we do not quote one. Sodium is listed at 41.1 and 39.3 ppm, noted as both naturally occurring and added during treatment. Hardness is measured at your own tap — we do that free.
$800 for a tank system, $900 tankless, both all-in with installation by a licensed plumbing professional, taxes and a lifetime parts warranty. Bundled with a softener the package is $2,850. The annual maintenance plan that covers filter changes is $199 a year. 0% financing is available.
