How many labs test for coliform bacteria in Georgia
16 labs on Georgia's official drinking-water lab list are certified to test for coliform bacteria. Of these, 16 hold a group certification that includes it. The Georgia list does not say which labs take samples from homeowners, so call a lab before you send one. 3 are located outside Georgia.
The list is published by the Georgia Environmental Protection Division (EPD) - Drinking Water Program, laboratory certification. List version on file: January 9, 2025. Fetched 2026-11-15 (UTC).
Old list. This list is from Georgia EPD's four certified-lab lists dated January 9, 2025 (chemical, microbiological, lead and copper, PFAS). They were still the newest lists on EPD's Drinking Water page when we checked on Nov 2, 2026. Labs may have been added, dropped or changed since then.
What this list covers. EPD's microbiological list is headed 'Commercial Laboratories', so labs certified only to test their own water system are not on it. The chemical list does not say which chemical groups each lab is certified for ('Not all labs are certified for all groups of chemicals'). Check the test with the lab.

Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for coliform bacteria in Georgia
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]
Georgia guidance that mentions coliform bacteria:
- The Georgia Department of Public Health (DPH) recommends testing private wells for coliform bacteria every year and doing a chemical screen (the W33C test, which includes arsenic and lead) every 3 years. [2]
- The bacteria test (W35) is available through your county public health department or UGA county Extension office. The W33C private well chemical test is available through UGA county Extension offices. [2]
- The UGA lab's Home Loan Closing package (W33B) covers lead, nitrate, nitrite and total coliform/E. coli, the four tests it says are commonly required for home closings. Ask your lender which tests it needs. [3]
Prices at UGA Agricultural and Environmental Services Laboratories fee schedule, effective Jul 1, 2026, as published when checked on 2 Nov 2026. Private certified labs set their own prices.
| Test | Price |
|---|---|
| Total coliform / E. coli (W35) | $40 [4] |
| Home loan closing: lead, nitrate, nitrite, coliform/E. coli (W33B) | $90 [4] |
About 1,514,397 people in Georgia used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [5] 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: Georgia.
