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.

TCLP analysis of the Coolside pellets and Ottawa base sand materials were completed. The metal concentrations for the 8 RCRA metals were well below the trigger values with all but Ag and Se being below the drinking water standard levels. The initial and final pH values showed the sand had essentially no neutralization capacity while the neutralization capacity of the pilot plant materials was above the 0.7 meq/g upper level for use of extraction solution [number sign]1 but well below the 2 meq/g upper level of the [number sign]2 solution neutralization capacity. Complete metals analysis in addition to the RCRA metals are also reported. Complete metals, proximate, and ultimate analyses for the pilot plant test samples were completed. Sizable concentrations of calcium well above the Coolside samples were observed. Interpretation of these results are in progress. Monitoring of swell on Coolside solid waste samples compacted in CBR molds continued with no increase in swell being observed since the last reporting period. The permeability of a specimen remolded near 95% of standard dry density and optimum moisture content and aged at room temperature for 178 days was 1.72 [times] 10[sup [minus]6] cm/sec.
