Explanation:
Lowering of the Water Table
Excessive pumping can lower the groundwater table, and cause wells to no longer be able to reach groundwater.
Increased Costs
As the water table lowers, the water must be pumped farther to reach the surface, using more energy. In extreme cases, using such a well can be cost prohibitive.
Reduced Surface Water Supplies
Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished.
Land Subsidence
Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.
Water Quality Concerns
Excessive pumping in coastal areas can cause saltwater to move inland and upward, resulting in saltwater contamination of the water supply.
