Among its implementation responsibilities, EPA must, by June 1987, develop and issue to the States technical guidance which they may use in determining the boundaries of a wellhead protection area and guidance and rule requirements for the receipt of Federal grant support under both the WHP and SSA programs. This workshop is intended to obtain a wide range of opinion which will assist EPA in developing this guidance. The participants of this workshop were selected to represent the groups involved in, or otherwise affected by, ground-water protection efforts. Among those represented are state and local governments, environmental groups, business and industry other federal agencies, and academic experts. The goal of this workshop is to provide a forum for these individuals and organizations to express their opinions and viewpoints.
