Water is essential to man. During peacetime or wartime, man needs to drink, cook, bathe, and relax. (In each of these events, water is in most cases a critical factor, just as food and shelter.) However, not faced with a shortage, the average American takes water for granted and consumes or uses more than is needed. What the average American does not realize is that over 97 percent of the water is in the ocean and that the other 3 percent is in atmospheric water vapor, surface fresh water, and ground water. Therefore, the fresh water that he thinks he is drinking is not fresh, so to speak, but reused water. About 25 percent of the fresh water is in soil formations located below the surface of the earth (aquifers), about 75 percent is permanently stored water located in the polar ice caps and glaciers, and less than one percent is located in our lakes and rivers.
