rivers and streams
• 700 springs (largest
concentration in the
world)
Water Consumption
Consequences
Groundwater depletion:
•
•
•
•
•
Dries out wetlands
Lowers lake levels
Reduces spring flows
Increases occurrence of sinkholes
Impairs water quality from saltwater
intrusion
Comparison of average gallons per
household per day
