Tests on the state list
This list does not break certification down by analyte. Ask the lab which tests it is certified for; the groups as written on the list are below.
Groups as written on the state list (1)
- Chemistry - Inorganic and Organic
- 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*').
DPHHS lists this lab under: Chemistry - Inorganic and Organic (Out-of-State Laboratories). The page names no analytes, certificate number or expiry date. "Chemistry - Inorganic and Organic" names no analyte, so no nitrate, metals or VOC certification is shown. Ask the lab.

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 Montana certification program.
