Understanding Tipton County’s Water

Drinking Water Quality Overview

EPA SDWIS

Tipton County earns a B grade for drinking water quality, scoring 69.0 out of 100. Over the past five years, EPA SDWIS records 1 health-based violation — a single incident worth monitoring.

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 substantial 40.0% of assessed waterways are impaired (20 of 50 water bodies) across Tipton County's watersheds. The leading impairment causes are physical substrate habitat alterations and escherichia coli (e. coli). 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 2026-05-14T14:00:00.000-05:00) puts HATCHIE RIVER at 3.9k cfs — near its historical average at 109% of mean flow. 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.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Tipton County has moderate coverage with 30 active monitoring sites with 5,496 recent measurements on record. Predominant monitoring categories include physical and nutrient. 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.

Editorial advisory

What the data suggests for Tipton County

Water Verdict

Tipton County, Tennessee receives a fair water quality assessment with a grade of B and a score of 69.0 out of 100. The water supply meets baseline federal standards, but there may be periods of elevated contaminant levels or infrastructure concerns worth monitoring. Separately, EPA ATTAINS assessments cover 50 water bodies in the county's watershed, with 40.0% listed as impaired under the Clean Water Act — a source-water measure that is tracked independently of tap-water compliance. At the most recent USGS reading, local streamflow was tracking near its historical mean (108.5%).

Violation Context

EPA SDWIS records for Tipton County, Tennessee show 1 health-based violation, meaning a water system experienced at least one exceedance of federal contaminant limits or treatment requirements. At 1.4 violations per 100,000 people served, this rate is relatively low compared to many U.S. counties. For independent context, 5,496 water-quality monitoring results have been recorded across the county in the EPA Water Quality Portal over the past five years.
