DPHHS State Environmental Laboratory page (https://dphhs.mt.gov/publichealth/laboratoryservices/environmentallaboratory): "We provide analytical, consulting, and training services to the general public and programs of the State of Montana, as well as local and federal agencies." The page offers 'Private Well Testing - Chemistry' and 'Private Well Testing - Microbiology' packages.

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: Chemistry - Inorganic and Organic (Montana Laboratories); Microbiology (Montana 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. "Chemistry - Inorganic and Organic" names no analyte, so no nitrate, metals or VOC certification is shown. Ask the lab.

Around this lab: Lewis and Clark County, MT

• Private wells: about 23,268 people, 35% of Lewis and Clark County’s 66,418 residents (USGS, 2015); rank 5 of 56 counties in Montana by people on wells.

• 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 2,763 private-well users (95% range 2,127 to 3,535; 2010 base), rank 3 of 56 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 48% of 34,082 housing units were built before 1980, about the same as the state share of 49%. 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 Montana certification program.
