However, over-pumping of groundwater can result in major problems. For instance, over-pumping groundwater depresses the water table, which in return can alter the di- rection of water flow. If a wetland (where the water table meets the surface) is adja- cent to a town that is over-pumping ground- water, the water can flow from the wetland towards the area of lowered water table, possibly causing the wetlands to dry up. a.
