Groundwater is the water that is found beneath the Earth's surface in the pores and fractures of rock formations. It is a vital natural resource that plays a crucial role in supplying water to wells and springs, and it also sustains flow in rivers and streams.
Groundwater is formed when precipitation seeps into the ground and percolates through soil and rock layers until it reaches a zone where all the pores and spaces between rock and soil particles are completely filled with water.
Groundwater is essential for drinking water supply, irrigation for agriculture, and maintaining the ecological balance of rivers and wetlands. It also serves as a natural storage system, holding water for long periods, and can mitigate the effects of droughts and water shortages.
By mastering these topics, you will gain a comprehensive understanding of groundwater and its significance in our environment and society.
