How the Indiana list marks public samples (whole list). Yes for IDOH's own laboratory (IDOH: "Samples are accepted from private citizens."). No for the out-of-state labs IDOH marks "THIS LAB DOES NOT ACCEPT SAMPLES FROM THE PUBLIC". Not stated for the other labs.
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 Indiana
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 1,677,339 people in Indiana 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: Indiana.
