Understanding Lee County’s Water

Drinking Water Quality Overview

EPA SDWIS

Lee County's water systems carry a failing grade, scoring 2.5 out of 100. Over the past five years, EPA SDWIS records 134 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 21.0% of assessed waterways carry an impairment designation (83 of 395 water bodies) across Lee County's watersheds. The leading impairment causes are turbidity - base flows and dissolved oxygen - critical. 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. Lee County has limited coverage with 6 active monitoring sites with 2,674 recent measurements on record. Predominant monitoring categories include physical and inorganics, minor, metals. 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.

What is the water quality in Lee County, Arkansas?
Lee County, Arkansas has a drinking-water quality grade of F with a score of 2.5/100, based on EPA SDWIS compliance data. The county has 134 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 134 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).

How healthy are the watersheds in Lee County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 21.0% of Lee County's 395 assessed water bodies are classified as impaired (83 impaired). The top reported causes are TURBIDITY - BASE FLOWS, DISSOLVED OXYGEN - CRITICAL, TURBIDITY - STORM FLOWS. 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 2,674 measurements from 6 monitoring sites in Lee County over the past five years. The most frequently measured characteristic groups are Physical, Inorganics, Minor, Metals, Nutrient. 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.
How does Lee County water compare to the Arkansas average?
Lee County's SDWIS water quality score of 2.5/100 is lower than the Arkansas state average of 47.6. The average water quality grade across Arkansas is D, based on data from 75 counties with available SDWIS data.
Is tap water safe to drink in Lee County?
Based on EPA SDWIS data, Lee County has a water quality grade of F (2.5/100). This indicates below-average compliance with significant violations. Residents may want to consider home water filtration or independent testing. The grade speaks to the public water system, not the watershed — for watershed-level concerns, see the Watershed Health zone. For the most up-to-date information, contact your local water utility or review your Consumer Confidence Report (CCR).
Why does Lee County have so many water violations?
Lee County has 134 health-based drinking water violations on record from the EPA SDWIS database. A higher violation count can result from aging infrastructure, underfunded water utilities, agricultural runoff contamination, or industrial pollution. Counties with more water systems may also see more violations simply due to scale. Residents concerned about water quality should consider independent water testing and home filtration systems.
How does Lee County rank for water quality in Arkansas?
Lee County ranks #74 out of 75 counties in Arkansas by SDWIS water quality score (1 = best). With a score of 2.5/100, it falls in the bottom third of counties statewide.
