Groundwater is, in general, easier and cheaper to treat than surface water, because it tends to be less polluted. Through wells, groundwater can be tapped where it is need, whereas surface waters are concentrated in lakes and streams.Chapter 3Surface Water: Rivers, Streams, and Lakes. Most of the earth 's water, about 97%, is the saltwater of the oceans. (See Figure 1.2 in Chapter 1.) By comparison, freshwater comprises only 3% of the earth's water, and surface water is only 0.3% of that 3%. Furthermore, rivers and lakes comprise 2% and 87%, respectively, of surface water. The amount of water in the atmosphere at any one time is trivial, equivalent to roughly 13,000 cubic km (about 3,100 cubic miles) of liquid water, or about 0.001 percent of the total at Earth’s surface. This water, however, plays an important role in the water cycle.Surface water often occurs because impervious areas are blocking water from soaking into the ground. Examples of impervious surfaces include roofs and pavement. Surface water is a major component of the water cycle. It can occur through either natural or manmade processes. It’s also the primary agent of soil erosion by water.Article Vocabulary Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. The ocean, despite being saltwater, is also considered surface water. Surface water participates in the hydrologic cycle, or water cycle, which involves the movement of water to and from the Earth's surface.1.
