Groundwater is a vital natural resource with several important uses that support human life and ecosystems.
Primary Applications of Groundwater
Groundwater serves multiple purposes, ranging from sustaining natural water bodies to supporting human consumption and vital economic activities like agriculture. Based on available information, its main uses include providing drinking water, facilitating agricultural irrigation, and helping to maintain the flow of rivers.
Agricultural Irrigation
The largest use of groundwater is for crop irrigation and agricultural production. This is critical for growing food and supporting the agricultural sector, which relies heavily on reliable water sources, especially in areas with limited surface water.
Drinking Water Supply
Groundwater is also a major source of water for human consumption. For instance, it is used for drinking water by close to 50% of the people in the United States. This makes it a fundamental component of municipal and private water supplies across the country.
Maintaining River Flow
Beyond direct human use, groundwater plays a crucial ecological role by helping to keep our rivers flowing. It contributes to the base flow of many rivers, ensuring they continue to have water even during dry periods, which is essential for aquatic ecosystems and downstream water users.
Groundwater's multifaceted utility highlights its importance as a resource that supports both human needs and environmental health.
