Understanding Little River County’s Water

Drinking Water Quality Overview

EPA SDWIS

Little River County's water systems carry a failing grade, scoring 23.8 out of 100. Over the past five years, EPA SDWIS records 11 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 23.4% of assessed waterways carry an impairment designation (48 of 205 water bodies) across Little River County's watersheds. The leading impairment causes are ph and turbidity - base 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 2026-05-14T13:15:00.000-05:00) puts Red River at 3.1k cfs — well below its long-term average at 18% 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. Little River County has limited coverage with 6 active monitoring sites with 1,525 recent measurements on record. Predominant monitoring categories include inorganics, minor, metals 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 Little River County

Water Verdict

Little River County receives a poor water quality assessment with a grade of F and a score of 23.8 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

Little River County has recorded 11 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 96.5 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

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 Little River County, Arkansas?
Little River County, Arkansas has a drinking-water quality grade of F with a score of 23.8/100, based on EPA SDWIS compliance data. The county has 11 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 Little River County?
Little River County has 11 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 Little River County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 23.4% of Little River County's 205 assessed water bodies are classified as impaired (48 impaired). The top reported causes are PH, TURBIDITY - BASE 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 Little River County?
EPA's Water Quality Portal records 1,525 measurements from 6 monitoring sites in Little River County over the past five years. The most frequently measured characteristic groups are Inorganics, Minor, Metals, Nutrient, Physical. 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 Little River County right now?
Little River County's primary USGS streamgage on the Red River has a pipeline snapshot of 3,090 cubic feet per second — 18% of the long-term mean of 17,357.86 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 Little River County water compare to the Arkansas average?
Little River County's SDWIS water quality score of 23.8/100 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 Little River County?
Based on EPA SDWIS data, Little River County has a water quality grade of F (23.8/100). 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 Little River County have so many water violations?
Little River County has 11 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 Little River County rank for water quality in Arkansas?
Little River County ranks #50 out of 75 counties in Arkansas by SDWIS water quality score (1 = best). With a score of 23.8/100, it falls in the middle 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.
