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 nitrate in Florida
Nitrate has no taste or smell, and a lab report can state the same water in two units that differ by a factor of 4.43. Read our nitrate explainer.
EPA advises private-well owners to test every year for total coliform bacteria, nitrates, total dissolved solids and pH. [1]
Florida guidance that mentions nitrate:
- The Florida Department of Health (DOH) strongly recommends testing private wells for bacteria and nitrate at least once a year, and says most homeowners should test for lead every three years. Depending on land use nearby, your county health department may suggest other tests. [2]
- In some cases, your county health department may be able to test for certain toxic substances free of charge. Ask whether it recommends any tests besides bacteria and nitrate. [2]
About 2,460,295 people in Florida used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [3] 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.
