An EPA health-based violation from 2024 is still open for Camino Real Regional Utility Authority, which supplies Santa Teresa, and its latest lead result (5.0 ppb) was higher than 90% of similar systems’, though under the 15 ppb action level. Santa Teresa has no town government of its own, so Doña Ana County runs its elections and most services, and its children attend Gadsden Independent Schools.
