- Public samples: ask the labNot 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." It names no lab, and NMED's list does not say which labs take samples from private well owners. NMED's free well testing (water fairs and NMED field offices) is done by NMED itself, not by the labs on this list.
- Location note
- Lab is in CO, certified by New Mexico (often used as a mail-in lab).

Groups as written on the state list (2)
- Pb/Cu = lead and copper
- IO = inorganics (NIT, FLU, CYA)
- Named on the official list The state list names this analyte (or a column for it) for this lab.
- Group-level certification Certified for a parent group (e.g. 'Inorganics') that includes this analyte. Confirm the specific test with the lab.
- Partial group certification The list marks the group as 'Partial'. Confirm this analyte with the lab.
- Subcontracted The lab sends this analyte to another accredited lab (MDH 'X*').
NMED prints the analyte groups as "Pb/Cu, IO" (codes keyed by the legend on NMED's list). NMED certifies whole analyte groups, not single analytes. NMED's legend defines IO as "inorganics (NIT, FLU, CYA)"; "NIT" is not spelled out (nitrate and/or nitrite), so no nitrate certification is shown from it. NMED's "On Contract" column: N. NMED's footnote: "Laboratories listed as "N" are not on contract with NMED-DWB and may not submit invoices for payment of sample analyses. Systems utilizing labs which are not under contract with NMED-DWB are responsible for payment of services." This concerns public water systems' compliance samples, not private well owners. Out-of-state lab (CO) certified by NMED-DWB. NMED's list prints city and state only, no street address.
Around this lab: La Plata County, CO
- Private wells: about 5,298 people, 10% of La Plata County’s 54,688 residents (USGS, 2015); rank 15 of 64 counties in Colorado by people on wells.
- At house sale: La Plata County Public Health Department has a septic system rule (La Plata County OWTS regulation, Continued Use Permit (section not cited in guide)). What it requires
- EPA radon zone (indoor air): Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
- Arsenic above 10 µg/L (USGS model): about 137 private-well users (95% range 110 to 176; 2010 base), rank 21 of 64 in the state. A screening estimate, not a measurement of any well.
- Older homes (Census ACS 2020–2024): 32% of 28,990 housing units were built before 1980, below the state share of 40%. Homes built before 1986 are more likely to have lead solder or fittings, so test tap water for lead there.
- PFAS in public water nearby (public supply, not your well): 1 public system serving this county reported EPA UCMR 5 results; 0 had a PFOA or PFOS sample at or above 4.0 ng/L.
County figures describe where the lab is, not the lab. Sources: USGS 2015 water use and 2017 arsenic estimates, EPA radon zones, Census ACS table B25034 (2020–2024), EPA UCMR 5 (2023–2026); details and links on the sources page.
Before you send a sample
Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the New Mexico certification program.
