Florida's unique geology creates distinctive water quality characteristics. The state sits atop the Floridan Aquifer, one of the most productive aquifers in the world, which provides drinking water for most Floridians. However, the porous limestone bedrock makes groundwater vulnerable to contamination, and saltwater intrusion poses challenges in coastal areas.

Based on our analysis of 96 cities in Florida, the average water quality score is 78/100. 21 cities have water quality scores below 70, indicating potential concerns that residents should be aware of. The highest-rated city is Safety Harbor with a score of 47/100, while Dunedin has the most room for improvement at 96/100.

Water Sources in Florida

Approximately 90% of Florida's drinking water comes from groundwater, primarily the Floridan Aquifer. Surface water from lakes and rivers supplements supply in some regions. Desalination is increasingly used in coastal communities facing saltwater intrusion. Springs throughout the state are fed by the same aquifer system.

Common Water Contaminants in Florida

These contaminants have been detected in various Florida water systems

1Sodium and chloride (saltwater intrusion)

2Nitrates (septic systems and agriculture)

3Radium (naturally occurring)

4Trihalomethanes (disinfection byproducts)

5PFAS (emerging contaminants near military bases)

6Sulfates (naturally occurring)

Florida Water Regulations

The Florida Department of Environmental Protection oversees drinking water programs. The state has been addressing PFAS contamination near military installations and working to reduce nutrient pollution affecting springs and aquifers. Florida requires regular testing and reporting for all public water systems.

Health Considerations

Residents in coastal areas should be aware of potential saltwater intrusion affecting their water supply. Areas with high septic tank density may have elevated nitrate levels. Some central Florida communities have naturally occurring radium that requires treatment. Hurricane damage and flooding can compromise water quality temporarily.

Recommendations for Florida Residents

Floridians should understand their local water source and treatment processes. Reverse osmosis effectively addresses most Florida water quality concerns including sodium and radium. Carbon filters help with taste and chlorine removal. After hurricanes, follow boil water notices carefully and flush plumbing systems before resuming normal use.

Frequently Asked Questions About Florida Water Quality

Is Florida's tap water safe to drink?

Water quality in Florida varies by location. Our analysis shows an average score of 78/100 across 96 cities, with 21 cities showing potential concerns. We recommend checking your specific city's water quality report and considering filtration if needed.

What are the main water quality concerns in Florida?

The most common water quality concerns in Florida include sodium and chloride (saltwater intrusion), nitrates (septic systems and agriculture), radium (naturally occurring). These contaminants can come from natural sources, industrial activities, or aging infrastructure. Review your city's specific report to see which contaminants affect your area.

Should I use a water filter in Florida?

Whether you need a water filter depends on your specific location and health concerns. With 21 cities in Florida showing elevated contaminant levels, residents in those areas may benefit from filtration. Look for filters certified by NSF/ANSI to remove the specific contaminants found in your area.

Where can I find my Florida water quality report?

Public water systems in Florida are required to provide annual Consumer Confidence Reports (CCRs) to residents. You can usually find your report on your water utility's website, request it by phone, or access it through the EPA's database. Our city-level reports above summarize key information from these official sources.
