Understanding Conway County’s Water

Drinking Water Quality Overview

EPA SDWIS

Conway 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 large 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 11.8% of assessed waterways carry an impairment designation (24 of 203 water bodies) across Conway County's watersheds. The leading impairment causes are turbidity - base flows and ph. 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. Conway County has moderate coverage with 13 active monitoring sites with 10,312 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.
