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 arsenic in Indiana
Arsenic is invisible, tasteless and mostly natural, and it comes in two forms that respond very differently to treatment. Read our arsenic explainer.

USGS estimates that the most private-well users with arsenic above 10 µg/L, EPA's limit for public water, live in Kosciusko County, Allen County and Madison County (about 8,677 people in Kosciusko County, 2010 base year). USGS describes this kind of estimate as useful "for broad screening of the population at risk", so it says nothing certain about any one well. [2]

USGS model estimate for broad screening, not a measurement of any well. Only a test tells you about your own well. Source: USGS, Estimated county level domestic well population with arsenic greater than 10 micrograms per liter (Ayotte, Medalie and Qi, 2017), accessed 2026-11-01.
About 1,677,339 people in Indiana used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [3] 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.
