Water Source
Miami-Dade WASD draws primarily from the Biscayne Aquifer, a shallow limestone aquifer that provides naturally filtered groundwater, supplemented by treatment for disinfection and hardness.
EPA Compliance Status
Meets all federal Safe Drinking Water Act standards.
Notable Contaminants & Context
- •Long-term saltwater intrusion into the Biscayne Aquifer from sea-level rise is a monitored regional planning concern for water managers, not a current safety issue in treated tap water
- •No significant compliance concerns in current supply
How It Compares
Aquifer-sourced systems like Miami's typically need less filtration than surface water systems, though South Florida water managers are actively planning for long-term aquifer resilience as sea levels rise.
Tips
- •A water softener addresses hardness/taste preference but isn't required for safety
- •Miami-Dade WASD publishes an annual water quality report
- •No need for bottled water around the city
