This report examines the importance of sole source aquifers of groundwater to the Nation's drinking water supply and how these aquifers are protected under Federal law. The report also includes a description of the sole source aquifers recognized by the Environmental Protection Agency and identifies the Congressional districts that overlie them. At this time, 17 sole source aquifers in 12 States have been designated, and they are located beneath all or parts of 49 Congressional districts.,CRS 84-573 ENR,"March 21, 1984.",SuDoc# LC 14. 18/3

Since 1979, the U.S. Environmental Protection Agency has expended considerable effort on developing an approach to protect groundwater from pollution. Because groundwater protection has traditionally been a right of the States, EPA sought to develop a groundwater protection strategy that would establish agency policy to protect groundwater under existing Federal statutes, but be sensitive to the rights and protection efforts of the States. EPA's efforts to prepare a groundwater strategy have been controversial and the strategy has been redrafted three times. This report compares and contrasts the three EPA groundwater strategies. EPA's executive summary of the proposed third version of the groundwater strategy is included in an appendix.,Abstract -- Overview of EPA's Groundwater Protection Strategy Development -- Groundwater Strategy #1. Key Concepts ; Approach -- Groundwater Strategy #2. Key Concepts ; Approach -- Groundwater Strategy #3.
