Solving Groundwater Overdraft in Arizona Urban Areas
- 215 Downloads
Arizona’s rapid economic and population growth since 1950 has relied heavily on mined groundwater. With limited surface water because of its generally arid climate, many parts of the State have experienced considerable groundwater overdraft. In 1980 the Arizona State Legislature passed the Groundwater Management Act (GMA) which was intended to limit ground water pumping for both agricultural and urban use in order to reduce the adverse effects associated with aquifer depletion. The GMA created administrative units called Active Management Areas (AMA) to carry out this reduction in groundwater use.
