Explanation:
Groundwater, as the name suggests, is water found underneath the surface of the earth. The water from rainfall, lakes, rivers, and streams seeps through the porous ground to reach the water table; a level where the ground beneath is saturated with water. Groundwater is usually contained in an aquifer. An aquifer can be described as a geological structure made of permeable components able to store large quantities of water. Groundwater is found in almost all places but the depth of the water table varies depending on the region, meteorological factors, and rate of exploitation. The amount of groundwater also changes with the season. In the rainy season, the water levels increase while in the dry season, the level of groundwater decrease.
Importance of Groundwater
Groundwater is an essential natural resource in most places. It makes up about 30% of the world’s freshwater reserve. It is often clean and easily accessible. In the United States, more than half of the population depends on groundwater as the primary source for their drinking water. In most farming areas where irrigation is practiced, groundwater is often used to irrigate the crops. In dry regions like Australia, groundwater provides a cheap water source because it is the most cost-effective to extract. In times of no rain, the groundwater plays a vital role in the environment by releasing water into rivers, lakes, and streams. As a result, groundwater prevents them from drying up. It also sustains the ecosystem by providing water for the vegetation when rainwater has dried up.
