Understanding Chicot County’s Water

Drinking Water Quality Overview

EPA SDWIS

Chicot County's water systems carry a failing grade, scoring 8.4 out of 100. Over the past five years, EPA SDWIS records 44 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 21.6% of assessed waterways carry an impairment designation (50 of 232 water bodies) across Chicot County's watersheds. The leading impairment causes are turbidity - base flows and turbidity - storm flows. 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 2026-05-14T13:45:00.000-05:00) puts Boeuf River at 5.5 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. Chicot County has limited coverage with 9 active monitoring sites with 1,503 recent measurements on record. Predominant monitoring categories include inorganics, minor, metals and physical. 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 Chicot County

Water Verdict

Chicot County, Arkansas receives a poor water quality assessment with a grade of F and a score of 8.4 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. Separately, EPA ATTAINS assessments cover 232 water bodies in the county's watershed, with 21.6% 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 Chicot County, Arkansas show 44 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 400.4 violations per 100,000 people served, this rate is high and signals significant water quality management issues. For independent context, 1,503 water-quality monitoring results have been recorded across the county in the EPA Water Quality Portal over the past five years.

Consumer Guidance

Chicot County has a Grade F compliance record with 44 health-based violations — among the highest levels in the country. Chicot County's drinking-water compliance score is 8.4 out of 100. Residents are strongly advised to use a certified NSF 58 reverse-osmosis filter or bottled water for all drinking and cooking until violations are corrected. Contacting the Arkansas Department of Environmental Quality or Health can expedite utility compliance action. Turbidity - Base Flows is the leading impairment cause in Chicot County's watershed. There are 9 active water-quality monitoring sites in Chicot County. A pipeline streamflow snapshot from the Boeuf River gauge is also available on this page.

Regional Context

Chicot County has poorer water quality than the average county in Arkansas. Its water score is 39.2 points lower than the state average, suggesting more challenges with contamination control or infrastructure than neighboring counties.

Impairment is determined under the Clean Water Act §303(d): a water body is impaired when it fails to meet state-defined quality standards for designated uses (drinking, recreation, aquatic life). Assessment coverage varies by state; counties without assessed water bodies are not shown.

Frequently Asked Questions

What is the water quality in Chicot County, Arkansas?
Chicot County, Arkansas has a drinking-water quality grade of F with a score of 8.4/100, based on EPA SDWIS compliance data. The county has 44 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 Chicot County?
Chicot County has 44 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). Violations may have been resolved — check with your local water utility for current status.
How healthy are the watersheds in Chicot County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 21.6% of Chicot County's 232 assessed water bodies are classified as impaired (50 impaired). The top reported causes are TURBIDITY - BASE FLOWS, TURBIDITY - STORM FLOWS, DISSOLVED OXYGEN - CRITICAL. 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 Chicot County?
EPA's Water Quality Portal records 1,503 measurements from 9 monitoring sites in Chicot County over the past five years. The most frequently measured characteristic groups are Inorganics, Minor, Metals, Physical, Inorganics, Major, 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 Chicot County right now?
Chicot County's primary USGS streamgage on the Boeuf River has a pipeline snapshot of 5.52 cubic feet per second — 1% of the long-term mean of 1,105.29 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 Chicot County water compare to the Arkansas average?
Chicot County's SDWIS water quality score of 8.4/100 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 Chicot County?
Based on EPA SDWIS data, Chicot County has a water quality grade of F (8.4/100). 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 Chicot County have so many water violations?
Chicot County has 44 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 Chicot County rank for water quality in Arkansas?
Chicot County ranks #67 out of 75 counties in Arkansas by SDWIS water quality score (1 = best). With a score of 8.4/100, it falls in the bottom third of counties statewide. The ranking reflects EPA SDWIS compliance only — not watershed impairment, monitoring density, or streamflow, which are tracked separately on this page.
