Understanding Miller County’s Water

Drinking Water Quality Overview

EPA SDWIS

Miller County earns an A grade for drinking water quality, scoring 86.0 out of 100. EPA's Safe Drinking Water Information System (SDWIS) records zero health-based violations over the past five years — a strong compliance signal for a small county.

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 notable 25.0% of assessed waterways carry an impairment designation (1 of 4 water bodies) across Miller County's watersheds. The leading impairment causes are mercury in fish tissue and fecal coliform. 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. Miller County has limited coverage with 6 active monitoring sites with 855 recent measurements on record. Predominant monitoring categories include physical and organics, pesticide. 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 Miller County

Water Verdict

Miller County, Georgia receives an excellent water quality assessment with a grade of A and a score of 86.0 out of 100. The water supply meets or exceeds federal safety standards, and residents can generally drink tap water with confidence. Separately, EPA ATTAINS assessments cover 4 water bodies in the county's watershed, with 25.0% listed as impaired under the Clean Water Act — a source-water measure that is tracked independently of tap-water compliance.

Violation Context

EPA SDWIS records for Miller County, Georgia show zero health-based violations, indicating that the county's water systems met all federal safety standards during the reporting period. The violation rate is zero per 100,000 people served, which is the best possible outcome. Independent monitoring is comparatively sparse here — 855 water-quality results logged in the EPA Water Quality Portal over the past five years — so the utility's own reporting carries extra weight.

Consumer Guidance

Tap water in Miller County has a clean compliance record with no health-based violations detected. Miller County's drinking-water compliance score is 86.0 out of 100. Mercury appears as a watershed impairment cause, which typically reflects fish-tissue accumulation rather than tap-water exposure. If you consume locally caught fish, consult your state's fish advisory. For drinking water, the current record supports confidence in the tap. There are 6 active water-quality monitoring sites in Miller County. Live streamflow monitoring from the SPRING CREEK APPROX .25 MI US US27 gauge is also available on this page.
