Jacksonville, Florida Drinking Water Quality (as of 2026)
Jacksonville’s drinking water is supplied primarily by JEA (Jacksonville Electric Authority), which serves over 800,000 people through the JEA Major Grid system. The water is sourced almost entirely from groundwater wells in the Floridan Aquifer, one of the most productive aquifers in the world.
Jacksonville Drinking Water Official Status
- Legally Safe: JEA’s water meets all federal (EPA) and state (Florida DEP) drinking water standards. The latest Consumer Confidence Reports (CCRs) state that the water is safe to drink and in full compliance.
Independent Analysis (EWG & Others)
While legally compliant, the Environmental Working Group (EWG) and TapWaterData report that Jacksonville water contains several contaminants above stricter health-based guidelines (not legal limits).
Key Contaminants of Concern
| Contaminant | Detected Level | EPA Legal Limit | EWG Health Guideline | Notes |
|---|---|---|---|---|
| Hexavalent Chromium (Chromium-6) | ~0.00142 ppb | 100 ppb | 0.02 ppb | Detected; probable carcinogen. |
| PFAS (including PFPeS, PFPeA) | Trace levels (e.g., 0.635 ppt for PFPeS) | 4 ppt (some compounds) | 0.3–1 ppt | “Forever chemicals” present. |
| Total Trihalomethanes (TTHMs) | Varies | 80 ppb | Lower | Disinfection byproducts from chlorination. |
| Haloacetic Acids (HAA5) | Detected | 60 ppb | Lower | Another disinfection byproduct. |
| Lead | Low at treatment plant | 15 ppb (action level) | 0.2 ppb (EWG) | Can increase in older pipes/homes. |
Summary from EWG: Jacksonville drinking water has multiple contaminants above EWG’s health guidelines, though still within legal limits. Many residents use filters for added protection, especially families with young children.
Current Areas of Concern
- Disinfection Byproducts — Due to chlorination of groundwater.
- PFAS — Trace amounts detected; a growing national concern.
- Aging Infrastructure — Potential for lead leaching in older neighborhoods.
- Vandalism & Security — Occasional incidents at facilities, though JEA maintains robust monitoring.
Future Concerns for Jacksonville Water Supply
- Saltwater Intrusion — A significant long-term risk for coastal Northeast Florida. Over-pumping of the Floridan Aquifer combined with sea-level rise is pushing saltwater further inland. This is already affecting some coastal wells in Duval and neighboring counties.
- Population Growth & Demand — Jacksonville is growing rapidly, increasing pressure on the aquifer.
- Climate Change — More frequent droughts and extreme weather can worsen intrusion and water quality.
- Regulatory Changes — Tighter PFAS and other contaminant rules may require expensive treatment upgrades in the coming years.
Jacksonville Drinking Water Bottom Line:
Jacksonville tap water is legally safe and drinkable for the vast majority of residents. However, like many Florida cities, it contains low levels of contaminants (especially disinfection byproducts and trace PFAS) that some health advocates consider concerning for long-term consumption.
Recommendations for Jacksonville Drinking Water:
- Review JEA’s latest Annual Water Quality Report (available on jea.com).
- Consider a certified filter (reverse osmosis or activated carbon) if you have specific health concerns.
- Test your home tap water for lead if you live in an older home.
