Understanding Mitchell County’s Water

Drinking Water Quality Overview

EPA SDWIS

Mitchell County's water systems carry a failing grade, scoring 1.7 out of 100. Over the past five years, EPA SDWIS records 160 health-based violations — a pattern that public water utilities are required to disclose and correct.

Watershed Conditions

EPA ATTAINS

Under the Clean Water Act §303(d), EPA ATTAINS tracks whether waterways meet quality standards for drinking, recreation, and aquatic life (reporting cycle: 2022). None of the assessed waterways are listed as impaired (0 of 3 water bodies) across Mitchell County's watersheds. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T13:45:00.000-05:00) puts SOLOMON R at 69.7 cfs — well below its long-term average at 18% of mean — low-flow conditions worth noting for water-dependent ecosystems. Streamflow is a leading indicator of drought stress, sediment load, and dilution capacity: low flows concentrate pollutants and warm water temperatures, stressing aquatic life and, in surface-water-dependent systems, the source water quality for treatment plants.

Editorial advisory

What the data suggests for Mitchell County

Water Verdict

Mitchell County, Kansas receives a poor water quality assessment with a grade of F and a score of 1.7 out of 100. The water supply has documented quality issues.

Separately, EPA ATTAINS assessments track 3 water bodies in the county's watershed, none of which are currently listed as impaired under the Clean Water Act. At the most recent USGS reading, local streamflow was below its historical mean at 18.1% — worth watching in drier seasons.
