Public / homeowner samples

Public samples: ask the lab

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." 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).

Tests on the state list

• 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 "HM, Pb/Cu, IO, SD" (codes keyed by the legend on NMED's list). NMED certifies whole analyte groups, not single analytes. NMED's legend defines HM only as "heavy metals" and names no metal, so no arsenic or other metal is shown from it. Lead and other metals are shown from Pb/Cu (lead and copper) only. 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 no street address; the address is from Washington's official list for the same lab (2773 Downhill Drive, Steamboat Springs, CO 80487).

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.
