Understanding Fluvanna County’s Water

Drinking Water Quality Overview

EPA SDWIS

Fluvanna 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 large 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 29.1% of assessed waterways carry an impairment designation (30 of 103 water bodies) across Fluvanna County's watersheds. The leading impairment causes are escherichia coli (e. coli) and benthic macroinvertebrates bioassessments. 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 2026-05-14T15:05:00.000-04:00) puts RIVANNA RIVER at 153.0 cfs — well below its long-term average at 21% 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.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Fluvanna County has moderate coverage with 25 active monitoring sites with 7,682 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 Fluvanna County

Water Verdict

Fluvanna County, Virginia 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 103 water bodies in the county's watershed, with 29.1% 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 below its historical mean at 21.3% — worth watching in drier seasons.

Violation Context

EPA SDWIS records for Fluvanna County, Virginia 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. For independent context, 7,682 water-quality monitoring results have been recorded across the county in the EPA Water Quality Portal over the past five years.

Consumer Guidance

The EPA compliance record for Fluvanna County shows no recent health-based violations. Fluvanna County's drinking-water compliance score is 86.0 out of 100. Watershed monitoring does show E. coli in local surface water — a reminder that treated drinking water and source-water quality are measured separately. Reviewing your utility's annual Consumer Confidence Report each July confirms that treatment is keeping pace with any upstream pressures. With 25 active water-quality monitoring sites in Fluvanna County, data coverage is strong. A pipeline streamflow snapshot from the RIVANNA RIVER gauge is also available on this page.
