How the Louisiana list marks public samples (whole list). LDH's chemistry list prints 'Accepts Commercial Samples: Yes/No' for each lab. 'Yes' means the lab accepts commercial samples, which is broader than 'homeowner', so call before you send a sample. The microbiology list does not say.
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 PFAS in Louisiana
EPA's 4.0 ng/L limits for PFOA and PFOS cover public water, not private wells, and its May 2026 proposals to roll back four other PFAS limits are not final. Read our PFAS explainer.
About 491,582 people in Louisiana used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [1] 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: Louisiana.
