MAFES: Desalination of Brackish Groundwater in Arizona - 01/27/13


600,000,000 acre-feet of brackish groundwater is estimated to be stored in Arizona aquifers.

While there are several key prospects in the state, major limitations to groundwater desalination remain, including energy costs associated with treatment and the difficulty with brine disposal, especially in Arizona. Current costs to produce fresh water from brackish water range from about $2 to $5 per 1,000 gallons.
