Sampling and Analysis

Laboratory Certification Procedure

The NMED Drinking Water Bureau maintains the Laboratory Certification Program in New Mexico for laboratories that are capable of analyzing water for biological and/or chemical contaminants.  The certification procedure follows the U.S. Environmental Protection Agency standards. Certification applications are received and reviewed by staff at the NMED Drinking Water Bureau.

Laboratories Currently Certified for New Mexico

Public water systems must have water samples analyzed at water laboratories that are certified by the State of New Mexico. A list of certified laboratories is available on this website for reference by public water systems.

Sample Collection Information

Public water systems (PWS) must be able to provide evidence of their water quality.  The evidence comes from monitoring of the water:

  • routine water samples collected and submitted for analysis
  • repeat water samples collected and submitted for analysis after evidence of unacceptable water quality has been discovered

All PWSs are responsible for assuring the monitoring and reporting requirements of 40 CFR 141 (National Primary Drinking Water Regulations) are met. Every PWS must have a certified operator or sampler collect all water quality samples for the distribution system.  Drinking Water Bureau employees are responsible for the collection of samples from the water source for the system.

Samplers Application (Forms, Schedules)

New Mexico certified operators and samplers who are associated with a New Mexico public water system can apply for a log-in to the online Drinking Water Sample Collection Application, which provides guidance, schedules and forms for public water system sampling. Sampling schedules can also be found on the Drinking Water Watch.

Sample Results by Individual Water System

The NMED Drinking Water Bureau provides a public portal for the statewide public water system database, Drinking Water Watch.  Sampling schedules and sample analysis results are available to all who have internet access.

Water Conservation Fund

The New Mexico Legislature established a fee assessed to public water systems to support the costs of their water sample analysis.  The New Mexico Tax and Revenue Department manages the collection of the fees.
