Figure 8. Schematic illustrating the effects of pumping from a well in an unconfined aquifer (left) and a confined aquifer (right). When unconfined aquifers are pumped, the water withdrawal leads to a drop in the water table, and the pore spaces become unsaturated. Pumping in confined aquifers decreases the water pressure, but the pore space remains fully saturated.
