Understanding Woodruff County’s Water

Drinking Water Quality Overview

EPA SDWIS

Woodruff 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 heavily urbanized 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 notable 17.4% of assessed waterways carry an impairment designation (93 of 536 water bodies) across Woodruff 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 2026-05-14T12:00:00.000-05:00) puts White River at 9.3k cfs — well below its long-term average at 37% 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. Woodruff County has moderate coverage with 18 active monitoring sites with 10,953 recent measurements on record. Predominant monitoring categories include nutrient 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 Woodruff County

Water Verdict

Woodruff County, Arkansas 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 536 water bodies in the county's watershed, with 17.4% 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 36.8% — worth watching in drier seasons.

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 Woodruff County?
EPA's Water Quality Portal records 10,953 measurements from 18 monitoring sites in Woodruff County over the past five years. The most frequently measured characteristic groups are Nutrient, Physical, Inorganics, Major, Non-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 Woodruff County right now?
Woodruff County's primary USGS streamgage on the White River has a pipeline snapshot of 9,350 cubic feet per second — 37% of the long-term mean of 25,428.67 cfs. This is well below typical — often a signal of drought stress on source water. For the latest gauge feed, visit waterdata.usgs.gov.
