PUBLIC NOTICE
IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Monitoring Requirements Not Met For Las Cruces Municipal Water System NM3511707
Our water system violated drinking water requirements over the past year. Even though this was not an emergency, as our customers, you have a right to know what happened and what we did to correct these situations.
*We are required to monitor your drinking water specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards. During November 2025 we failed to conduct required source water monitoring within the designated timeframe, following a Total Coliform-positive sample and, therefore, cannot be sure of the quality of our drinking water during that time.*
What should you do?
There is nothing you need to do at this time.
What does this mean?
One requirement of public water systems is the periodic monitoring of tap water for the presence of bacterial contaminants. Whenever our water system has a routine Total Coliform-positive sample, we are required by law to conduct source water monitoring within 24 hours of notification. Following a Total Coliform-positive sample on November 6, 2025 we did not collect the required source water sample within the time frame designated by the state. Therefore, we cannot be sure of the quality of your drinking water during that time.
What happened?
Las Cruces Municipal Water System failed to collect the required triggered source water monitoring samples following a Total Coliform positive sample on November 6, 2025. According to Section 20.7.10.100 NMAC [incorporating 40 CFR 141.402(a)(21)], ground water systems must collect, within 24 hours of notification of the total coliform-positive sample, at least one ground water source sample from each ground water source in use at the time the total coliformpositive sample. Some samples collected did not have facility ID#s that match up with their respective facility names on the lab request forms. Also, the sampler ID# was incomplete on the forms, therefore these samples (written as wells 46 and 59) were not in compliance.
