| Quick fact | Details |
|---|---|
| Utility | Williamsburg Public Water Supply (PWSID 4884023), Iowa County |
| Water source | Groundwater from Wells 4, 5A, 6 and 7. The 2025 report states the supply comes from "the buried sand and gravel of the Buried Sand and Gravel aquifer," rated low susceptibility to contamination by the Iowa DNR |
| Softened at the plant? | No softening process is described in the 2025 report and no hardness figure is published — we measure yours at the tap instead of guessing |
| One distinguishing fact | The 2025 report carries fresh sampling: sodium 24 ppm (7/15/2025) and combined radium 1.3 pCi/L (10/21/2025), with a lead 90th-percentile result of 3.00 ppb against a 15 ppb action level and no violations |
Williamsburg sits on a different kind of water than most of the towns around it. Instead of drilling deep into Jordan sandstone, the city draws from a buried sand-and-gravel aquifer — an ancient channel of sand and gravel sealed under clay — which the Iowa DNR source water assessment rated low susceptibility to contamination from the land surface. That combination, shallow-ish but well-sealed, is unusual and worth knowing.
The 2025 report is current and specific. Sodium came in at 24 ppm on 7/15/2025 — low, and consistent with a supply that is not municipally softened. Combined radium measured 1.3 pCi/L on 10/21/2025, well under the 5 pCi/L limit. The lead result from the 2024 monitoring round shows a 90th-percentile figure of 3.00 ppb against a 15 ppb action level, with a range from non-detect to 11 ppb across sampled homes; in these reports lead is attributed to corrosion of household plumbing, which is why results vary house to house rather than tracking the source water. The city publishes reports from 2017 through 2025 on williamsburgiowa.gov.
One caution if you are researching this yourself: the top search result for "City of Williamsburg water quality report" is often Williamsburg, Kansas, complete with a hardness figure that has nothing to do with Iowa County. We checked, discarded it, and are not publishing a hardness number Williamsburg, Iowa has not released.
Spotted glassware, film on the shower door, soap that refuses to lather, stiff laundry, and scale quietly accumulating inside the water heater. It is a maintenance and comfort issue rather than a safety one — and it is the reason most people in this part of Iowa County end up with a softener.

Iowa County is farm country, and the acreages outside the city system are on their own wells with no annual report. The Iowa DNR recommends testing every year for bacteria and nitrate, and Iowa's Private Well Grants program covers free county lab testing through your county environmental health office — do that before you buy any equipment.
Shallow and alluvial wells in this part of the state are the ones most worth watching for nitrate. Iowa State University extension materials note that nitrate is odorless and tasteless and that reverse osmosis, distillation and anion exchange remove it, while the CDC notes boiling does not remove chemical contaminants. See our nitrates page, well water guide, and free well testing.
