Certified labs by state
New Mexico
New Mexico relies heavily on groundwater for drinking water, and the state says over 170,000 residents depend on private wells. State guidance for private wells is split mainly between the New Mexico Environment Department (testing, certified labs, water fairs) and NMDOH/NMTracking resources for well owners.

- NMED identifies arsenic, uranium, nitrate, and fluoride as some of New Mexico's most problematic chemical contaminants (NMED Water Resources & Management).
- NMED water fairs provide free field testing for arsenic, electrical conductivity, fluoride, iron, nitrate, pH, and sulfate (NMED Water Fairs).
- NMED field offices provide free screening of private domestic wells for nitrate, iron, and fluoride only (NMED Free Well Water Testing).

What to do next
- Start with NMED's Private Wells page, then use the certified lab list to order a private-well package that includes coliform bacteria, nitrate, arsenic, and uranium.
- If you want a low-cost first screen, check NMED Water Fairs or the field-office testing program before paying for broader certified-lab testing.
- If your area has mining, agriculture, fuel storage, old plumbing, or known PFAS concerns, add location-specific tests beyond the basic annual panel.
