Understanding Franklin County’s Water

Drinking Water Quality Overview

EPA SDWIS

Franklin County's water systems carry a failing grade, scoring 40.2 out of 100. Over the past five years, EPA SDWIS records 36 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 20,272 water bodies) across Franklin County's watersheds. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Franklin County has extensive coverage with 62 active monitoring sites with 22,842 recent measurements on record. Predominant monitoring categories include organics, other and inorganics, minor, metals. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.
