As shown in Figure 14.12, pumping of well C has contributed to well B going dry. If pumping continues in well C, it too may go dry. Figure 14.11 Three wells in an unconfined aquifer. Well A is not being pumped.Question. Saltwater intrusion is likely to occur when (a) a cone of depression is created near a coastal ecosystem. (b) humans drill into a confined aquifer near the coast. (c) farmers irrigate their crops with an excess of saline water. (d) an artesian well is created near the coast. (e) the soil near a coastline allows for rapid water drainage.

water level lowers, ie., drawdown occurs in the well. A cone of depression is formed in the aquifer around the pumping well as the water level declines due to pumping. Note that drawdown in the observation well is much less than in the pumping well. A pumping test should also measure the changes in water level after the pump stops (see Figure 2).Water Supply Problems: Resource Depletion.
