Understanding Evans County’s Water

Drinking Water Quality Overview

EPA SDWIS

Evans 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 large majority — 77.8% — of assessed waterways are impaired (7 of 9 water bodies) across Evans County's watersheds. The leading impairment causes are mercury in fish tissue and dissolved oxygen. 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 2026-05-14T14:15:00.000-04:00) puts CANOOCHEE RIVER at 2.1 cfs — well below its long-term average at 1% 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. Evans County has limited coverage with 2 active monitoring sites with 718 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 Evans County

Water Verdict

Evans 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 9 water bodies in the county's watershed, with 77.8% 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 0.5% — worth watching in drier seasons.

Violation Context

EPA SDWIS records for Evans 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 — 718 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 Evans County has a clean compliance record with no health-based violations detected. Evans 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 2 active water-quality monitoring sites in Evans County. A pipeline streamflow snapshot from the CANOOCHEE RIVER gauge is also available on this page.

Regional Context

Evans County has better water quality than the average county in Georgia. Its water score is 21.6 points higher than the state average, indicating stronger water system performance relative to neighboring counties.

Frequently Asked Questions

What is the water quality in Evans County, Georgia?
Evans County, Georgia has a drinking-water quality grade of A with a score of 86.0/100, based on EPA SDWIS compliance data. The county has 0 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 Evans County?
Evans County has 0 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). Zero violations is an excellent record indicating consistent compliance with federal drinking water standards.
How healthy are the watersheds in Evans County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 77.8% of Evans County's 9 assessed water bodies are classified as impaired (7 impaired). The top reported causes are MERCURY IN FISH TISSUE, DISSOLVED OXYGEN, FECAL COLIFORM. 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 Evans County?
EPA's Water Quality Portal records 718 measurements from 2 monitoring sites in Evans County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Organics, Other. 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 Evans County right now?
Evans County's primary USGS streamgage on the CANOOCHEE RIVER has a pipeline snapshot of 2.14 cubic feet per second — 1% of the long-term mean of 456.98 cfs. This is well below typical — often a signal of drought stress on source water. For the latest gauge feed, visit waterdata.usgs.gov.
How does Evans County water compare to the Georgia average?
Evans County's SDWIS water quality score of 86.0/100 is higher than the Georgia state average of 64.4. The average water quality grade across Georgia is C, based on data from 159 counties with available SDWIS data.
Is tap water safe to drink in Evans County?
Based on EPA SDWIS data, Evans County has a water quality grade of A (86.0/100). This indicates good to excellent water quality with strong SDWIS compliance.
