The main source of freshwater usage is groundwater. While surface water sources (such as rivers, lakes, and reservoirs) are important, groundwater accounts for a significant portion of the freshwater used for irrigation, drinking water, and industrial processes. Glaciers and ice caps also hold a considerable amount of freshwater, but they are not typically used directly for consumption or agriculture. Oceans, on the other hand, contain salty water and are not a source of freshwater.
