Overview: Florida Well Water Rules
Florida's sandy geology and shallow water table make it vulnerable to contamination from septic systems and agricultural runoff, yet the state has no point-of-sale testing mandate. Private well owners are advised to test annually, particularly for bacteria and nitrates. The FDOH recommends a comprehensive panel every 5 years for all private well owners.
What Must Be Tested in Florida
| Parameter | Standard | Requirement |
|---|---|---|
| Coliform bacteria | Absent | Loan-required; FDOH recommends annual |
| Nitrate | ≤10 mg/L | Loan-required; elevated risk near agriculture |
| Arsenic | ≤0.010 mg/L | Elevated in some areas — test proactively |
| Additional parameters | Per region | FDOH recommends comprehensive test every 5 years |
Finding a State-Certified Lab in Florida
Florida requires testing through a state-certified laboratory. To find a lab:
- Contact your county health department — many maintain a local lab referral list
- Search the Florida Department of Health (FDOH) Well Surveillance Program website for a list of certified labs
- Use our national certified lab finder guide for resources
Do not use a DIY kit or an uncertified online mail-in service for loan transactions or state-required testing. Results must come from a FDOH-certified laboratory.
Federal Loan Requirements in Florida
Regardless of Florida's state requirements, federal loan programs impose their own standards:
- VA loans: Always require a water quality test, results valid 90 days. VA guide →
- FHA loans: Require testing when proximity triggers are met (well within 100 ft of septic, etc.). FHA guide →
- USDA loans: Always require testing, results valid 180 days. USDA guide →
I’m buying with cash in Florida — do I need a well water test?
For a cash purchase in Florida, there is no legal requirement in most situations. However, conducting your own water quality test is strongly recommended. A basic certified lab test costs $100–$200 and is far less expensive than discovering contamination after closing.
How much does well water testing cost in Florida?
A basic certified lab panel in Florida (coliform + nitrates + pH) typically costs $75–$150. A comprehensive panel meeting loan requirements runs $150–$350. Some county health departments offer subsidized testing programs — call your county health office to check. See our full cost guide for more detail.
