Understanding Charlotte County’s Water

Drinking Water Quality Overview

EPA SDWIS

Charlotte County's water systems carry a failing grade, scoring 18.9 out of 100. Over the past five years, EPA SDWIS records 5 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). A notable 28.4% of assessed waterways carry an impairment designation (33 of 116 water bodies) across Charlotte 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 2026-05-14T14:45:00.000-04:00) puts CUB CREEK at 58.9 cfs — running somewhat below its historical average at 61% of mean. 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. Charlotte County has moderate coverage with 29 active monitoring sites with 3,623 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 Charlotte County

Water Verdict

Charlotte County receives a poor water quality assessment with a grade of F and a score of 18.9 out of 100. The water supply has documented quality issues. Residents are strongly encouraged to use filtered or bottled water for drinking and to stay informed about utility improvement plans.

Violation Context

Charlotte County has recorded 5 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 142.4 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

Consumer Guidance

Drinking-water compliance in Charlotte County is rated Grade F, reflecting significant health-based violations in the recent reporting period. Charlotte County's drinking-water compliance score is 18.9 out of 100. An NSF 53 or NSF 58-certified filter is recommended for drinking and cooking water. Check the Consumer Confidence Report from your utility to identify the specific contaminants and required corrective actions — utilities are legally required to notify customers of violations. E. coli is the leading impairment cause in Charlotte County's watershed. With 29 active water-quality monitoring sites in Charlotte County, data coverage is strong. A pipeline streamflow snapshot from the CUB CREEK gauge is also available on this page.

Regional Context

Charlotte County has poorer water quality than the average county in Virginia. Its water score is 38.8 points lower than the state average, suggesting more challenges with contamination control or infrastructure than neighboring counties.

Frequently Asked Questions

What is the water quality in Charlotte County, Virginia?
Charlotte County, Virginia has a drinking-water quality grade of F with a score of 18.9/100, based on EPA SDWIS compliance data. The county has 5 health-based drinking water violations over the past 5 years. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Charlotte County?
Charlotte County has 5 health-based drinking water violations recorded by the EPA over the past 5 years. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs).

Impairment means the water body fails to meet state quality standards for at least one designated use — drinking water source, recreation, aquatic life, or fish consumption. Note: watershed impairment doesn't always translate to tap-water issues; treatment plants can remove most regulated contaminants.
How much water-quality monitoring happens in Charlotte County?
EPA's Water Quality Portal records 3,623 measurements from 29 monitoring sites in Charlotte County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Microbiological. Each measurement is a single sample analyzed for one characteristic (E. coli, pH, dissolved oxygen, etc.). High monitoring density means more scientific evidence behind any reported signal — it does not by itself indicate water quality.
What's happening with rivers in Charlotte County right now?
Charlotte County's primary USGS streamgage on the CUB CREEK has a pipeline snapshot of 58.9 cubic feet per second — 61% of the long-term mean of 95.98 cfs. Flow is within typical range for this gauge. For the latest gauge feed, visit waterdata.usgs.gov.
