Detailed explanation-1: -Pumping groundwater faster than it can recharge can lead to dry wells, especially during droughts. Groundwater is a valuable resource both in the United States and throughout the world.
Detailed explanation-2: -A variety of supply sources and methods are used to intentionally recharge aquifers. Common methods include filling dedicated recharge basins or ponds, directing water to unlined canals and riverbeds, injecting water through wells, and using extra surface water (when available) to avoid pumping (“in-lieu recharge”).
Detailed explanation-3: -Groundwater overdraft occurs when groundwater use exceeds the amount of recharge into an aquifer, which leads to a decline in groundwater level.
Detailed explanation-4: -Excessive groundwater pumping can overdraft aquifers, emptying them faster than natural systems can replenish them. Overdraft can result in wells going dry, saltwater intrusion, depletion of surface water supplies, and cause the land to collapse (i.e., subsidence).
