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*').

Microbiological certification is listed per lab only; the list does not name the tests. Confirm coliform / E. coli testing with the lab. MO marks the lab 'Commercial' (performs analyses for hire): microbiological list Yes.

Homeowner service and turnaround (lab’s own website)

• Takes homeowner samples: yes. The lab’s site says: “Property owners may submit samples from private wells or other drinking water sources for bacterial testing.” source
• Who collects: You collect the sample with the lab's bottles. source

From the lab’s own website, read 15 Nov 2026 and re-read by a second checker; next check due by 13 Feb 2027. Certification fields come from the state list only.

Prices the lab prints, compared

• Bacteria (coliform / E. coli): $10 here, the same as the state-run lab’s $10 (Routine well bacteria test (total coliform and E. coli), handling fee; Missouri State Public Health Laboratory, Bacteriology Private Water Test Request form MO 580-3168 (11-2022); chemical test fees are not published, checked 2 Nov 2026) source.
• Bacteria (coliform / E. coli) against other Missouri labs: median $20 across 4 other labs that print a price on their own site; 0 of them charge less than $10.

Comparison uses the lowest single-test price this lab prints; panels and ranges are left out. For comparison only, not a quote.

Around this lab: Cole County, MO

• Private wells: about 11,890 people, 15% of Cole County’s 76,720 residents (USGS, 2015); rank 21 of 115 counties in Missouri by people on wells.

• EPA radon zone (indoor air): Zone 2: moderate potential (average indoor radon may be between 2 and 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 116 private-well users (95% range 86 to 158; 2010 base), rank 33 of 115 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 47% of 33,533 housing units were built before 1980, below the state share of 53%. 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): 4 public systems serving this county reported EPA UCMR 5 results; 1 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 Missouri certification program.
