what is a possible long term consequence of groundwater overdraft

Full Answer

What is one of the possible negative effects of overdraft of groundwater?

Groundwater overdraft almost always causes groundwater level declines and surface water depletion, and sometimes leads to degradation of groundwater quality and land subsidence.

What are the negative effects of groundwater depletion?

Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence. Such effects, while variable, happen to some degree with any ground-water use.

What are the problems caused by over ground water?

Excessive pumping can lower the groundwater table, and cause wells to no longer be able to reach groundwater. 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.

What happens if groundwater decreases?

A groundwater shortage keeps additional water from flowing into lakes, rivers and seas. This means that over time, less water will enter as the existing surface water continues to evaporate. As the water becomes less deep, it will affect everything in that particular region, including fish and wildlife.

What are the effects of the overuse and depletion of groundwater?

Over and above the loss of water resources, groundwater overdraft can harm surface water rights; diminish river flows; impact fish, animal, and plant communities that depend on groundwater; increase energy costs from pumping; and result in economic impacts on agriculture that depends on groundwater.

What happens if the groundwater level gets too high?

Water close to the underside of the basement floor can rise up through the slab and cause dampness. If groundwater levels are higher than the basement floor, water can leak in through the walls and floor and you'll have standing water.

What are the long term consequences of groundwater overdraft?

The possible long-term consequences of groundwater overdraft is the unproductive wells.

Why is groundwater reduced?

Groundwater results in reduced in supply of water reason being groundwater pumping costs, groundwater contamination, aquifer depletion or cost of well deepening.
