Aquifer Storage and Recovery: The Solution to South Florida’s Water Scarcity?

Jessica Pollock

Water Resources

Fall 2005

why need for asr
Why need for ASR?
  • Everyday, 1.7 billion gallons of water are diverted from the Everglades and drained off both east and west coasts
  • This water historically flowed through the Everglades recharging the Biscayne and Floridan Aquifers
  • Not enough water for domestic/municipal, agricultural, and ecosystem
why continued
Why? continued
  • South Florida population expected to double within 40 years
  • ASR does not require large land acreage, as does water storage areas
  • Ecosystems suffer
    • Florida Bay, Everglades, saline coastline environments
what is asr
What is ASR?
  • Treatment of water to drinking standards
  • Pumping of water into Floridan Aquifer
  • Later recovery of stored water
  • Has been used in Florida since 1983
  • Will take 20 years to complete
  • Will be largest ASR project in world
slide6
Floridan Aquifer has natural salty brine
  • Freshwater pumped into aquifer will have zone of mixing
  • Freshwater will create a “bubble”
plans
Plans
  • Water from ‘wet season’ is to be stored for further usage in ‘dry season’ – also tourist season
  • Water storage is planned for multi-year usage
  • Wells capacity of 5 MGD to equal 1.6 to 1.7 billion GD pumping capacity
slide8
Largest ASR project ever undertaken
  • 3 pilot projects currently ongoing since 2000
  • Pilot projects will continue until 2008
  • If results successful, larger construction will take place
concerns
Concerns
  • Comprehensive Everglades Restoration Plan (CERP) relies heavily on ASR success for restoration
  • CERP expects 70% recovery rate, may be too optimistic
  • 5 MGD wells – 2 to 5 times higher than currently used in Florida
  • Physical and Chemical properties should be expected to vary at each site – water as well
concerns11
Concerns
  • East coast wells seem more productive than West coast wells
  • Treated water injected into natural brine – chemical interactions, potential release?
  • Will water be potable when recovered?
  • Multi-year use has never been done in FL
  • Fractured bedrock
  • Regional changes in flow patterns
  • DIW of wastewater
advantages
Advantages
  • Acts as above ground reservoir, without the evaporation
  • Requires less land
more advantages
More Advantages
  • Natural Aquifers – natural surface water recharges
  • Will allow for more steady flow in Everglades – species rebound?
  • More environmentally sound and cost effective than alternatives
  • Will provide flood protection after many ACOE provisions taken out
slide15
The Everglades Restoration is a “microcosm of the entire environmental movement.”

- largest ASR project in the world

-largest constructed wetland in the world
