| Abstract: | The hydrologic response to development of three of the most heavily pumped sedimentary aquifer systems in the United States is similar in some aspects and different in others. In the semiarid West, an unconfined sand aquifer and a confined sand and clay aquifer system have been subjected to withdrawals that are far greater than predevelopment recharge rates resulting in large losses of ground water from storage. In the humid East, pumpage from a carbonate aquifer system has resulted in induced recharge and diversion of natural discharge with insignificant loss from storage. However, the following responses to development are common in all three aquifer systems: 1) ground-water circulation has increased, 2) rates of recharge have increased-mostly due to recirculation of pumped ground water, or infiltration of imported surface water used for irrigation in the semiarid West, 3) locations of recharge areas have changed, and 4) natural discharge has decreased. -from Author |
