EL PASO, Texas (KTSM) — The Camino Real Regional Utility Authority (CRRUA) released its latest arsenic water sample tests on Thursday, Sept, 19, where all arsenic treatment facilities have met federal guidelines for this month, the utility said in a press release. The CRRUA says the federal limit is 10 parts per billion (ppb) and it has provided the arsenic test results for September which are the following: Sample LocationArsenic Treatment Facility (ATF)Sample Result (ppb)Arsenic MCL 10 (ppb)Sunland Park8.4Below MCLSanta Teresa Community6.4Below MCLSanta Teresa Industrial Park6.6Below MCLBorder EntryExcludedN/ATest results were released by Eurofins Environment Testing, a water testing lab certified by the New Mexico Environment Department (NMED). Data provided by the CRRUA. The utility says it excluded the Border Entry treatment facility from its monthly testing due to its continued meeting of all New Mexico Environment Department requirements. The NMED also recently completed its third-quarter arsenic tests from water samples that were collected in July at all four arsenic treatment facilities. Test results show that the CRRUA's arsenic levels remain below the Environmental Protection Agency's maximum contaminant level (MCL) for drinking water of 10 ppb. Those results are the following: Sample location: Arsenic treatment facility (ATF)Sample Result (ppb)Arsenic MCL 10 (ppb)Santa Teresa Border Entry ATF3.0Below MCLIndustrial Park Arsenic ATF4.0Below MCLSunland Park Arsenic ATF9.0Below MCLSanta Teresa Community5.0Below MCLNMED results from July 30.
