Understanding Aleutians East Borough’s Water

Drinking Water Quality Overview

EPA SDWIS

Aleutians East Borough's water systems carry a failing grade, scoring 3.4 out of 100. Over the past five years, EPA SDWIS records 28 health-based violations — a pattern that public water utilities are required to disclose and correct.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T10:15:00.000-08:00) puts RUSSELL C at 166.0 cfs — running somewhat below its historical average at 63% of mean. 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. Aleutians East Borough has limited coverage with 5 active monitoring sites with 204 recent measurements on record. Predominant monitoring categories include physical and inorganics, major, non-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.
