Results of third quarter 2026 (July – Sept.) arsenic tests conducted by the New Mexico Environment Department (NMED) Drinking Water Bureau (DWB) show that all four arsenic treatment facilities (ATF) operated by the Camino Real Regional Utility Authority (CRRUA) remain NMED compliant based on the department’s Running Annual Average (RAA.)

Tests results from samples the NMED DWB took on July 15, 2026, show that water treated at all four ATFs is below the federal Maximum Contaminant Level (MCL) for arsenic of 10 parts per billion (ppb): Border Entry ATF at 5.0 ppb, Santa Teresa Industrial ATF at 5.0 ppb, Santa Teresa Community ATF at 4.0 ppb, and the Sunland Park ATF at 7.0 ppb. 

“This is the seventh straight NMED quarterly compliance test period in which all four CRRUA ATFs passed based on the RAA,” CRRUA Executive Director Juan Crosby said.

The RAA is determined by adding the previous four quarterly NMED test results for each ATF and dividing each total by four.

“CRRUA continues to remain compliant with arsenic standards under the Safe Drinking Water Act,” Crosby added.
