How many labs test for coliform bacteria in Alaska
25 labs on Alaska's official drinking-water lab list are certified to test for coliform bacteria. All 25 are named for coliform bacteria on the list. The Alaska list does not say which labs take samples from homeowners, so call a lab before you send one. 1 is located outside Alaska.

How the Alaska list marks public samples (whole list). No for the labs DEC's microbiology page marks with *** ("Indicates a laboratory that does not accept samples from the public."). Not stated for the other labs: the page does not say positively that a lab takes samples from the public.
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 Alaska
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]
About 188,794 people in Alaska used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [2] 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: Alaska.
