The ZIP codes associated with Belen Water System have a median household income of $51,537 and about 21,375 residents live in those ZIP codes (Census; not the number of people this system supplies). Approximately 54% of housing stock was built before 1986, which increases the likelihood of lead service lines and older plumbing.

Environmental Justice Note: On average, 67% of census tracts in the counties mapped to this service area are designated disadvantaged by the federal Climate and Economic Justice Screening Tool (CEJST, 2022 version). Communities with higher disadvantaged populations often face disproportionate environmental and health burdens, including aging water infrastructure and limited resources for remediation.

💧 Where Does Your Water Come From?

Groundwater

Belen Water System's water is classified in EPA records as a groundwater source. Groundwater is naturally filtered through rock and soil, but it can be vulnerable to PFAS contamination, nitrates from agriculture, and industrial chemicals that seep into the water table.

System Overview

Belen Water System (EPA ID: NM3524932) is a community water system in New Mexico that serves approximately 10,830 people from groundwater sources.

This system serves ZIP code 87002 in Belen.

ZIP-Area Home Safety Context: C (67/100)

This is the average Home Safety Score for 1 of 1 service-area ZIP codes with all required score domains observed. It is not a grade for the water utility.

Model 4.0.0 uses SDWIS identity plus accepted ECHO SDWA lifecycle-based water compliance, the UCMR 5 PFAS MCL screen, EPA radon zone, and annual EPA AirData AQI across three equally weighted domains. Missing required evidence suppresses the score.

Violation History

8 current health-based noncompliance records in the accepted 2026Q2 snapshot.

Federal UCMR5 PFAS Monitoring: No PFAS Reported Above Reporting Levels

This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). No PFAS compounds were reported above UCMR5 minimum reporting levels.

Samples collected
174

EPA's April 2024 PFAS rule sets MCLs of 4 ppt for PFOA and PFOS and 10 ppt for PFHxS, PFNA and HFPO-DA (GenX); water systems must comply from 2029. Other PFAS compounds have no individual federal MCL. A state standard is shown only where this system's state has its own enforceable PFAS limit. Detection results are EPA UCMR5 samples, not a measurement at your tap.

Frequently Asked Questions

Is water from Belen Water System safe to drink? ▼
Belen Water System has 89 recorded violations since 2021. The C shown is a ZIP-area score, not a grade for this utility; see the violation table for what was violated.
Should I use a water filter? ▼
Given 89 recorded violations, review the violation types and dates; a filter certified for a specific contaminant of concern can reduce that contaminant at the tap. Monitoring or reporting violations are not something a filter addresses.
How many people does Belen Water System serve? ▼
Belen Water System serves approximately 10,830 people with drinking water across 1 ZIP code.
What is Belen Water System's water source? ▼
Belen Water System draws water from groundwater sources. Source type affects which contaminants are most likely to be present.
Is there lead in Belen Water System's water? ▼
The reported 90th-percentile lead result is below the laboratory reporting limit, not a measured zero; EPA's health goal for lead is zero. This is at or below the EPA lead action level, which triggers system action and is not a safe level; the EPA health goal for lead is zero.
What is the demographic profile of the ZIP codes associated with Belen Water System? ▼
The ZIP codes mapped to Belen Water System have a median household income of $51,537 (Census ZIP-code estimate). In CEJST data, 67% of census tracts in the counties mapped to this area are designated disadvantaged (average across mapped ZIP codes), which may indicate greater vulnerability to environmental health risks.
Where does Belen Water System get its water? ▼
Belen Water System's water is classified in EPA records as a groundwater source. Groundwater is naturally filtered through rock and soil, but it can be vulnerable to PFAS contamination, nitrates from agriculture, and industrial chemicals that seep into the water table. The available violation history and environmental indicators place this system in the elevated review category; they do not measure current source contamination.
