The Camino Real Regional Utility Authority (CRRUA) passed its monthly operational control arsenic tests for September 2025, as verified by an independent laboratory. CRRUA provides water and wastewater services to Sunland Park and Santa Teresa, NM.

The Environmental Protection Agency (EPA) Maximum Contaminate Level (MCL) for arsenic is 10 parts per billion (ppb). 

Test results released by Eurofins Environment Testing; a water lab certified by the New Mexico Environment Department (NMED) show the Sunland Park Arsenic Treatment Facility (ATF) at 4.1 ppb, Santa Teresa Community ATF at 4.5 ppb, and Santa Teresa Industrial ATF at 3.0 ppb. All three are below the EPA MCL. Results are from samples taken Sep. 2, 2025. 

CRRUA excluded Border Entry ATF from its monthly voluntary testing due to its continued meeting of all NMED requirements.

“CRRUA is compliant with arsenic standards under the Safe Drinking Water Act, and our Arsenic Treatment Facilities continue to operate as intended. We are committed to maintaining full transparency by publicly sharing results from both regulatory samples and operational control testing,” said CRRUA Executive Director Juan Crosby. 

Arsenic tests results are available on the CRRUA website crrua.org.
