Understanding White Pine County’s Water

Drinking Water Quality Overview

EPA SDWIS

White Pine County's drinking water earned a C grade, scoring 52.9 out of 100. Over the past five years, EPA SDWIS records 1 health-based violation — a single incident worth monitoring.

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). None of the assessed waterways are listed as impaired (0 of 1 water bodies) across White Pine County's watersheds. 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 2026-05-14T11:00:00.000-07:00) puts CLEVE CK at 5.7 cfs — well below its long-term average at 56% 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. White Pine County has moderate coverage with 44 active monitoring sites with 11,363 recent measurements on record. Predominant monitoring categories include inorganics, minor, metals and inorganics, major, 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.

Editorial advisory

What the data suggests for White Pine County

Water Verdict

White Pine County, Nevada receives a below-average water quality assessment with a grade of C and a score of 52.9 out of 100.
