How the New Mexico list marks public samples (whole list). Not stated per lab. NMED's Private Wells page says: "To test your water, contact a local water laboratory and confirm if they can analyze samples from private wells. While the Drinking Water Bureau (DWB) certifies laboratories for public water systems, many of these labs also offer services to private well owners." Neither that page nor NMED's list says which labs take samples from private well owners.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for coliform bacteria in New Mexico
About a third of the 397 domestic wells tested for bacteria in a national USGS study had total coliform. Read our coliform bacteria explainer.
EPA advises private-well owners to test every year for total coliform bacteria, nitrates, total dissolved solids and pH. [1]
New Mexico guidance that mentions coliform bacteria:
- NMED's Drinking Water Bureau suggests testing every spring for common contaminants such as coliform bacteria and nitrates. Its list of recommended tests is bacteria, nitrate and arsenic every year, and uranium every five years. NMED says this is general guidance, not a regulatory requirement. [2]
About 292,165 people in New Mexico used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [3] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: New Mexico.
