Indiana labs
One laboratory is independently verified to accept private-well drinking-water samples from citizens: the Indiana Department of Health (IDOH) Laboratories in Indianapolis. The other rows are in-state laboratories transcribed from IDEM’s Indiana Certified Drinking Water Laboratories PDF revised 11/7/2025, from the section labeled “Labs that accept samples from the public.” Municipal utilities that appear in that public-accepting section are included. Appearance on the list is not an endorsement. Call before you collect water. Private-well acceptance beyond the PDF’s “accept samples from the public” wording is not independently verified except for IDOH.
What we could and could not verify
- The IDEM PDF separates labs that accept samples from the public from labs that do not. This directory transcribes only the public-accepting section (49 laboratories). The non-public section is not tabulated — see the PDF.
- Municipal utilities listed in the public-accepting section are kept (unlike Ohio/Michigan pages, where municipal plants were omitted because those lists did not claim public acceptance).
- Except for IDOH Laboratories, we have not independently verified private-well / homeowner acceptance beyond the PDF’s public-samples wording. Call before you collect.
- The PDF text layer is multi-column and messy. City of Goshen Water Lab and Elkhart Public Works & Utilities Laboratory both print lab ID M-20-01; Pace Analytical Services, LLC (Indianapolis) prints only C-49-06 (same C-id string as EMSL). Kept as printed. Five labs have no website on the PDF (marked unknown).
- Certification summaries may truncate long analyte lists with “…”. Prices are intentionally omitted even when the IDOH well-water page shows dollar amounts. Order IDOH kits via Access Indiana (link the IDOH page; kit process details beyond that page are not invented).

Labs that accept samples from the public (IDEM list)
Call to confirm they still hold certification for the tests you need, that they will take your private-well sample, and how to ship or drop off. Mail vs. drop-off is unknown unless noted. 1 of 49 transcribed rows is independently verified for private-well testing (IDOH, above). Accepts column “Yes (PDF: public samples)” means the lab is in the PDF’s public-accepting section — not an independent private-well verification.
