Can drought affect the water level in wells?
Ground water, which is found in aquifers below the surface of the Earth, is one of the Nation’s most important natural resources. Ground water is used to provide a large portion of the Nation’s population with drinking water, it provides business and industries water for their purposes, and is used extensively for irrigation. The water level in the aquifer that supplies a well does not always stay the same. Droughts, seasonal variations in rainfall, and pumping affect the height of the underground water levels. If a well is pumped at a faster rate than the aquifer around it is recharged by precipitation or other underground flow, then water levels in the well can be lowered. This can happen during drought, due to the extreme deficit of rain. The water level in a well can also be lowered if other wells near it are withdrawing too much water.
