OverviewOverview

Desalination Opportunities Vary Greatly By Source And Location

Arizona Lacks Linkages Between Regulations and Policies For Rapid Adoption Of Desalination Technologies

Institutional Relationships Vary: International, Multi-state, Regional, and Local Collaborations

Assured Water Supply Assured Water Supply RequirementsRequirements

Groundwater Management Act (1980) Active Management Areas “Safe-yield” Goal Most Groundwater Pumping is “Mined” No Relief For Poor-qualify Aquifers

GW Management AreasGW Management Areas

Prescott AMA: safe-yield by 2025

Phoenix AMA: safe-yield by 2025

Tucson AMA: safe-yield by 2025

Pinal AMA:preserve agriculture as long as feasible while preserving

groundwater for future needs

(1,000 feetr depth to water limit)

Santa Cruz AMA:maintain safe-yield,

prevent long-term water table declinesINA – Irrigation

Goals

Aquifer Protection Aquifer Protection ProgramProgram

Protects All Aquifers From Impairment All Discharges

YDP Example No Relief For Poor-qualify Aquifers

No provisions for deep well injection Reduced options for wetlands/halophytes
