Understanding De Baca County’s Water

Drinking Water Quality Overview

EPA SDWIS

De Baca 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 mid-sized 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 13.9% of assessed waterways carry an impairment designation (5 of 36 water bodies) across De Baca County's watersheds. The leading impairment causes are benthic macroinvertebrates and specific conductivity. 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 2026-04-22T15:15:00.000-06:00) puts PECOS RIVER at 244.0 cfs — running significantly above its long-term average at 175% of mean flow. 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. De Baca County has limited coverage with 4 active monitoring sites with 1,618 recent measurements on record. Predominant monitoring categories include organics, other and inorganics, minor, 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.
