This is a record of the first scientific results for the coordinated environmental science program currently sponsored by the US Department of Energy. The purpose of the program is to lay the foundation for remediating the nuclear weapons production legacy in the United States, the most expensive environmental program ever attempted. The papers presented in this volume cover the actinide, inorganic, analytical, physical, biogeochemistry, and separative chemistry areas of this program.
