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*').

DPHHS lists this lab under: Microbiology (Out-of-State Laboratories). The page names no analytes, certificate number or expiry date. Microbiology: the program page says DPHHS certifies labs that analyze Montana's public drinking water supplies for "chemical and microbiological contaminants" under the Safe Drinking Water Act, where the microbiological drinking-water tests are total coliform / E. coli; the page names no organism or method, so bacteria is shown as a certified group, not a named test. Ask the lab which coliform test it runs. DPHHS prints only a PO Box for this 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.
