Laboratory Certification Procedure

The NMED Drinking Water Bureau (DWB) maintains the Laboratory Certification Program in New Mexico for drinking water analyses.  The Department of Health Scientific Laboratory Division (SLD) is the assigned Principle State Laboratory as required by the U.S Environmental Protection Agency (EPA) for New Mexico State Primacy.

Laboratories that are capable of analyzing water for biological and/or chemical contaminants may apply to the New Mexico Environment Department's Drinking Water Bureau to be certified for water analysis for New Mexico. Certified laboratories must also be under contract with the State of New Mexico, through the State's procurement process, in order to be paid by the State for water analysis (see NM General Services Department State Purchasing Division website for details about vendor contracts).
