Systems with a yearly average at or above an EPA-based study benchmark
1.4%1 of 74 active community water systems
All 74 systems had enough required samples to calculate a yearly average. 1 had at least one yearly average at or above a study benchmark; 73 did not.
EPA-based study benchmark: the unrounded cutoff this research uses to reproduce EPA’s January 2026 technical-assistance classification around the April 2024 federal levels. It is not a current standard or compliance finding and cannot determine household exposure or health risk.

Community water systems with complete monitoring
“Complete monitoring” means at least one sampling location had all required samples needed for a yearly average. Each PWSID appears once, preventing double counting across ZIP associations.

How the count works
What is included
Each active community water system with enough required samples for a yearly average is counted once, even if it is linked with several ZIP codes. This does not mean every home was tested. Private wells are excluded, and UCMR 5 did not comprehensively monitor every small system. This page does not apply New Mexico's state-specific standards or determine compliance. Use the official state or territory drinking-water program for current regulatory information.
