Why test for coliform bacteria in Missouri
About a third of the 397 domestic wells tested for bacteria in a national USGS study had total coliform. Read our coliform bacteria explainer.
EPA advises private-well owners to test every year for total coliform bacteria, nitrates, total dissolved solids and pH. [1]
Missouri guidance that mentions coliform bacteria:
- DHSS says to test each year for total coliform bacteria, E. coli and nitrate, and for other contaminants you suspect. Also test if there are known well water problems in your area, after flooding, land disturbance or nearby waste disposal, or after you repair or replace any part of the well system. If you live in an area with current or past mining, DHSS recommends a metals test. [2]
- The Missouri State Public Health Laboratory tests private well samples for total coliform and E. coli (iron bacteria by special request) and also offers chemical tests: a New Well Series (fluoride, chloride, nitrate, sulfate, iron, manganese and lead), typically run when a well is first installed, and a full panel of minerals, nutrients and metals. [2]
- Samples must reach the lab within 48 hours of collection, in a kit supplied by the lab through local public health agencies. The lab tests about 7,000 private water samples for bacteria each year. [3]
Prices at Missouri State Public Health Laboratory, Bacteriology Private Water Test Request form MO 580-3168 (11-2022); chemical test fees are not published, as published when checked on 2 Nov 2026. Private certified labs set their own prices.
| Test | Price |
|---|---|
| Routine well bacteria test (total coliform and E. coli), handling fee | $10 [3] |
About 821,343 people in Missouri used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [4] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Missouri.
