Understanding Lee County’s Water

Drinking Water Quality Overview

EPA SDWIS

Lee 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 largely rural 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 substantial 40.0% of assessed waterways are impaired (2 of 5 water bodies) across Lee County's watersheds. The leading impairment causes are escherichia coli (e. coli) and ph. 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 2026-05-14T15:00:00.000-04:00) puts LYNCHES RIVER at 154.0 cfs — well below its long-term average at 22% 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. Lee County has limited coverage with 2 active monitoring sites with 207 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 Lee County

Water Verdict

Lee County, South Carolina 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 5 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 below its historical mean at 22.1% — worth watching in drier seasons.

Violation Context

EPA SDWIS records for Lee County, South Carolina 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 — 207 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

The EPA compliance record for Lee County shows no recent health-based violations. Lee 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. There are 2 active water-quality monitoring sites in Lee County. A pipeline streamflow snapshot from the LYNCHES RIVER gauge is also available on this page.

Regional Context

Lee County has better water quality than the average county in South Carolina. Its water score is 21.1 points higher than the state average, indicating stronger water system performance relative to neighboring counties.

Frequently Asked Questions

What is the water quality in Lee County, South Carolina?
Lee County, South Carolina 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 Lee County?
Lee 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 Lee County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 40.0% of Lee County's 5 assessed water bodies are classified as impaired (2 impaired). The top reported causes are ESCHERICHIA COLI (E. COLI), PH. 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 Lee County?
EPA's Water Quality Portal records 207 measurements from 2 monitoring sites in Lee County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Inorganics, Minor, Metals. 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 Lee County right now?
Lee County's primary USGS streamgage on the LYNCHES RIVER has a pipeline snapshot of 154 cubic feet per second — 22% of the long-term mean of 696.57 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 Lee County water compare to the South Carolina average?
Lee County's SDWIS water quality score of 86.0/100 is higher than the South Carolina state average of 64.9. The average water quality grade across South Carolina is C, based on data from 46 counties with available SDWIS data.
Is tap water safe to drink in Lee County?
