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 arsenic in Florida
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 Palm Beach County, Osceola County and Lee County (about 3,454 people in Palm Beach 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. [1]

| Item | Value | Note |
|---|---|---|
| Palm Beach County | 3,454 people (2010 base year) | |
| Osceola County | 3,272 people (2010 base year) | |
| Lee County | 2,748 people (2010 base year) | |
| St. Lucie County | 2,426 people (2010 base year) | |
| Clay County | 2,142 people (2010 base year) | |
| Putnam County | 2,088 people (2010 base year) |
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 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.
