Groundwater irrigation expanded the agricultural production capacity of the United States, but higher crop yields came with an environmental cost. Indiscriminate pumping of groundwater to support agriculture has led to severely depleted aquifer levels. Today, nearly 30 percent of all US groundwater withdrawals occur within the High Plains aquifer, which underlies parts of Colorado, Kansas, Oklahoma, New Mexico, and Texas (McGuire et al., 1999). As previously mentioned, a Kansas research study has identified significant areas of its aquifer which, due to depletion, will be unusable in 25 years or less (Buddemeier et al., 2000). Nevertheless, the federal government continues to support nationwide irrigation infrastructure and energy requirements with annual irrigation subsidies totaling $2.2 billion dollars (Edwards and DeHaven, 2001).
