Is Your Water Safe?

All water systems that serve at least fifteen service connections or regularly serve an average of at least twenty-five individuals daily at least 60 days out of the year are considered to be Public Water Systems (PWS) and are regulated under the Safe Drinking Water Act (SDWA).

To learn more about any PWS in New Mexico, including general system information, sampling schedules, sampling results and violations, go to the DRINKING WATER WATCH website and enter the system name or number. You can also search for a listing of systems by county, system type or primary water source type.

A Drinking Water Advisory is issued if a public water system has a violation for exceeding the Maximum Contaminant Level (MCL) for a chemical contaminant, such as nitrate. A Boil Water Advisory is issued if a system has or is suspected to have microbiological contamination. You can view a list of all systems that have or have had DRINKING WATER ADVISORIES OR BOIL WATER ADVISORIES

If you rely on a PRIVATE WELL for your drinking water, SDWA does not apply to you and the Drinking Water Bureau does not regulate your water quality. The Drinking Water Bureau has developed GUIDANCE FOR PRIVATE WELL OWNERS that addresses water testing, potential sources of contamination, shock chlorination, and strategies to protect your well from contamination. You can also get information on private wells on the EPA's WEBSITE FOR PRIVATE WELL OWNERS.   If you have any concerns about the quality of your well water, you should have it tested at a certified laboratory. For information on particular drinking water contaminants, go to the Contaminants page.  For information on microbiological and chemical testing laboratories in New Mexico, go to the Laboratory Certification page.
