美国对地下水的管理较早,例如,1885年在康涅狄克州的一般性法中就有关于地下水权的条文。有的水法几经修订,逐步完善。例如,1948年制定的亚利桑那州地下水法则,1980年又重制订颁布新的亚利桑那州综合性的地下水管理条例,这被视为美国地下水管理规章的典范。自五十年代以来,美国有些州(主要是中西部)对地下水源的依靠日益加重。例如从1955年至1975年,地下水用水量不断增长,其中,俄勒冈增 In the United States, groundwater management was earlier. For example, in the general law of Connecticut in 1885, there was a provision on groundwater rights. Some water laws have been revised, and gradually improved. For example, the Arizona Groundwater Code, enacted in 1948, again enacted in 1980 to enact new comprehensive Arizona groundwater regulations, is considered a model for groundwater regulation in the United States. Since the 1950s, the dependence of some states in the United States (mainly the Midwest) on groundwater sources has been increasing. For example, from 1955 to 1975, groundwater water use continued to grow, with Oregon adding
