All of the listed consequences can be caused by overpumping of groundwater. A cone of depression occurs when there's excessive drawdown of water, and subsidence and compaction of an aquifer happen when the pore space collapses due to a decrease in water pressure. Changes in the direction of groundwater flow can happen when a gradient is disturbed by over-extraction, and bringing contamination into previously uncontained wells is possible if a drawdown creates a new pathway for pollutants to enter.
