Understanding Hooker County’s Water

Drinking Water Quality Overview

EPA SDWIS

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). A large majority — 100.0% — of assessed waterways are impaired (3 of 3 water bodies) across Hooker County's watersheds. The leading impairment causes are escherichia coli (e. coli) and mercury in fish tissue. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.
