Description: Preparations are nearing completion to begin the field lysimeter and laboratory lysimeter studies. Approval has not yet been received to place the Coolside wastes in the field lysimeters. Winter wig delay emplacement of the waste until the weather moderates. Much of the technical progress for January centered on preliminary evaluation of Coolside samples for laboratory lysimeter testing and development of chemical analysis techniques. Approximate estimates of element concentrations in the leachate from Coolside waste allows the analytical group to anticipate the analytical requirements for the first lysimeter leachate samples. The preliminary leaching studies will also provide a guide to the evolution of Coolside materials with time and with continual replacement of pore waters. California Bearing Ratio tests were performed on three Coolside samples varying in degree of density compaction produced by the Standard, Modified, and Low Energy techniques.
