Of the freshwater available on Earth, about two-thirds is frozen in ice caps and glaciers, which leaves only a small fraction accessible for human use. Surface water—such as that in lakes, reservoirs, rivers, and streams—is the primary water source for humans. Groundwater—that ties are usually sufficient only for drinking purposes.
