Editorial analysis

Understanding Doña Ana County’s Water

Drinking Water Quality Overview

EPA SDWIS

Doña Ana County has limited drinking water data on file. Violation data are unavailable for this 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 small share — 4.8% — of assessed waterways are impaired (4 of 84 water bodies) across Doña Ana County's watersheds. The leading impairment causes are polychlorinated biphenyls (pcbs) and boron. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

Editorial advisory

What the data suggests for Doña Ana County

Water Verdict

Doña Ana County does not have sufficient EPA SDWIS water quality data to determine an overall assessment. Residents should contact their local water utility for the most recent Consumer Confidence Report.

Violation Context

Health-based violation data is not available for Doña Ana County. EPA health violations occur when water systems exceed allowable contaminant levels or fail to meet treatment requirements. Residents should request the latest Consumer Confidence Report from their water provider.

Consumer Guidance

Drinking-water compliance data is not yet available for Doña Ana County in the EPA SDWIS system, which is common for rural areas and census areas served by private wells or small tribal systems. Residents should contact their local utility or state drinking-water agency for the most current Consumer Confidence Report. Using an NSF-certified filter (look for certifications against ANSI/NSF 53 or 58) can provide additional safety margin for any unconfirmed contaminants. Polychlorinated Biphenyls (Pcbs) is the leading impairment cause in Doña Ana County's watershed.

Regional Context

State-level water quality comparison data is not available for Doña Ana County. When data is available, this section will show how the county's water quality compares to other counties in New Mexico.

Advisory text summarizes county-level public records and is not a replacement for your utility's current Consumer Confidence Report or direct local notices.

Frequently Asked Questions

What is the water quality in Doña Ana County, New Mexico?
Doña Ana County, New Mexico has a drinking-water quality grade of N/A with a score of N/A/100, based on EPA SDWIS compliance data. Compliance data is currently unavailable. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Doña Ana County?
Violation data for Doña Ana County is not currently available. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs).
How healthy are the watersheds in Doña Ana County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 4.8% of Doña Ana County's 84 assessed water bodies are classified as impaired (4 impaired). The top reported causes are POLYCHLORINATED BIPHENYLS (PCBS), BORON, ESCHERICHIA COLI (E. COLI). 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 does Doña Ana County water compare to the New Mexico average?
Doña Ana County's SDWIS water quality score of N/A/100 is not available for comparison. The average water quality grade across New Mexico is F, based on data from 32 counties with available SDWIS data.
Is tap water safe to drink in Doña Ana County?
Based on EPA SDWIS data, Doña Ana County has a water quality grade of N/A (N/A/100). Insufficient data is available to fully assess compliance. The grade speaks to the public water system, not the watershed — for watershed-level concerns, see the Watershed Health zone. For the most up-to-date information, contact your local water utility or review your Consumer Confidence Report (CCR).
Does Doña Ana County have clean drinking water?
Doña Ana County has no reported health-based drinking water violations according to EPA records. With a water quality score of N/A/100 and grade N/A, the county's drinking water has had some compliance issues but continues to be monitored. Note: drinking-water compliance speaks to the public water system, not necessarily to the watershed itself — check the Watershed Health zone for ATTAINS §303(d) data.
How is water quality measured?
WaterByCounty layers four federal datasets per county. The A–F drinking-water grade comes from EPA SDWIS (Safe Drinking Water Act compliance, 5-year violation lookback). The Watershed Health zone surfaces EPA ATTAINS §303(d) impairment data. The Monitoring zone summarizes EPA Water Quality Portal records. The Streamflow zone reports the latest USGS NWIS reading from the county's primary streamgage. Each is reported separately so you can see where the water is actually weakest.

Data Sources

Drinking-water compliance data from the EPA Safe Drinking Water Information System (SDWIS) via the ECHO enforcement database. Scores reflect compliance history and health-based violation counts.

Watershed health and impaired-waterway data from the EPA ATTAINS Clean Water Act §303(d) assessments, state-reported and EPA-finalized.
