From the Paper:
"The type of water we generally use in human activities is freshwater. Only 3% of the world's water supply is freshwater and two-thirds of that is frozen, forming the polar ice caps, glaciers, and icebergs. The remaining 1% of the total world water supply is freshwater available as either surface water or ground water; ground water accounts for two-thirds of this amount. Surface water is water that is visible above the ground surface, such as creeks, rivers, ponds and lakes. Ground water is water that either fills the spaces between soil particles or penetrates the cracks and spaces within rocks. Most people get their water from ground water sources. Roughly 9 out of every 10 public water systems. Public water systems operate wells to tap ground water and just over half of the total population served by Public water system drinks water from a ground water source. Millions more get their water from private wells which also tap ground water sources. Ground water systems tend to serve smaller numbers of people, while surface water systems generally serve large populations. The quantity and quality of the world's water supply depends on how we choose to use water. Our use can be consumptive, which means that the water is not returned to nature (such as drinking water), or noncomsumptive. Nonconsumptive use returns water, polluted or not, to the system. Creating hydroelectric power is an example of nonconsumptive use. "
