Old list: check before you rely on it
EGLE's out-of-state, radiological, in-state PFAS, out-of-state PFAS and Cryptosporidium lists are dated 9/8/2025, more than 12 months before we fetched them on Nov 2, 2026, though EGLE's program page still links them. Labs and analytes on them may have changed since. EGLE's chemistry, microbiological and lead and copper lists (3/11/2026) are not affected.

Before you send a sample
Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Michigan certification program.
