Overview
Albuquerque secured its water future with the San Juan-Chama project, importing Colorado River basin water to rest its aquifer, and the city's supply meets all federal standards. Santa Fe blends reservoirs, wells, and the same imported water.
New Mexico's risks are rural and mineral: naturally occurring arsenic and uranium in groundwater (the uranium-mining legacy on and near Navajo lands left hundreds of unremediated sites and contaminated wells), plus PFAS plumes at Cannon and Holloman Air Force bases that rank among the nation's worst.
Common Contaminants in New Mexico
Naturally elevated across Rio Grande rift groundwater; Albuquerque treats and blends, and small systems account for most exceedances
Mining legacy plus natural occurrence affects wells in the Grants belt and Navajo Nation communities, many outside public-system regulation
Cannon AFB's plume contaminated dairy wells near Clovis in one of the country's starkest agricultural PFAS cases; Holloman's lakebed levels are among the highest recorded
Violations & Compliance
Albuquerque, Las Cruces, and Santa Fe comply fully. Small-system arsenic exceedances are the routine violation; uranium-legacy and base-plume cleanups run as long-term federal projects.
