How many labs test for radon in water in Florida
7 labs on Florida's official drinking-water lab list are certified to test for radon in water. All 7 are named for radon in water on the list. None of them is marked as taking samples from the public. Call a lab before you send a sample. 7 are located outside Florida.
The list is published by the Florida Department of Health (DOH) - Environmental Laboratory Certification Program (NELAP). List version on file: DOH Version: 11/07/2026 08:30:01 (Qlik app refresh 11/9/2026 4:26:47 AM; live database). Fetched 2026-11-15 (UTC).

How the Florida list marks public samples (whole list). Not stated per lab. Marked yes only for DOH's Bureau of Public Health Laboratories in Jacksonville and Miami (DOH's Well Water Testing page: "Testing is provided at the Jacksonville and Miami laboratories", "$40 for private testing through BPHL"). DEP's Laboratory page, which links this list, tells the public to "contact only commercial laboratories from the results, as utility, university, research, and state laboratories do not accept public samples"; that is a general rule (DOH's own BPHL labs are state labs that do test private wells), so it is quoted on each non-commercial lab, not used as the flag.
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 radon in water in Florida
Most of the risk from radon in a well comes from breathing the gas the water releases indoors, not from drinking it. Read our radon in water explainer.
EPA's radon zone map puts 0 of Florida's 67 counties in Zone 1 (highest potential), 9 in Zone 2 and 58 in Zone 3. [1] That map is about radon in indoor air, and EPA says it should not be used to decide whether an individual home needs testing. If radon is found in your air and you have a well, EPA suggests testing the water too.
About 2,460,295 people in Florida 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: Florida.
