Overpumping of groundwater can cause saltwater intrusion, especially in coastal areas, as the pumping creates a cone of depression that pulls in saltwater from surrounding areas. This can contaminate previously freshwater wells and make the water unusable for drinking or irrigation. Inflation of the aquifer due to an increase in porosity is not a possible consequence, as overpumping can actually cause the aquifer to collapse or subside. Flooding due to rising groundwater levels is also not a likely consequence, as overpumping causes the opposite effect of lowering groundwater levels.
