Regulating groundwater in the Eastern United States (U.S.), particularly transboundary aquifers between states, is a challenge given the patchwork quilt of common law, statutory frameworks, and agency rules. Such regulation is made more challenging by the need for better quantification of pumping and use. These dynamics are exemplified through several case studies, including the first ever U.S. Supreme Court case related to groundwater withdrawals (set in the Eastern U.S.). As dynamics such as expanded irrigation, population increases, and ecological considerations influence groundwater use across the Eastern U.S., water use will continue to be an important driver for economic activity and interaction within and between states. To effectively regulate transboundary aquifers, governance solutions must incorporate current science into decision making and be implemented at local, state, regional, and federal scales.

合理使用？：美国东部跨界地下水监管的挑战

鉴于普通法，法规框架和代理机构规则错综复杂，对美国东部（US）特别是州际跨界含水层的地下水进行监管是一项挑战。由于需要更好地定量泵送和使用，这种调节变得更具挑战性。这些动态通过几个案例研究得到了证明，其中包括美国最高法院首例与地下水抽取有关的案例（在美国东部发生）。随着不断扩大的灌溉，人口增加以及生态因素等因素影响美国东部地区的地下水使用，用水将继续成为经济活动和各州之间以及各州之间相互作用的重要驱动力。为了有效监管跨界含水层，
