This report consists of 3 monthly progress reports. The first represents a summary of results from mineralogical studies of the field lysimeter samples. This part of the project is an ongoing task to understand the long term mineralogical reactions that occur in the lysimeters as a function of static loading (compaction) and moisture content. The data is congruent with results obtained from geotechnical characterization of pre-aged and non-aged Coolside samples with and without surcharge. The investigations are expected to aid in the understanding of the processes that control permeability and leaching potential of the materials and to produce sufficient information on the physical and chemical nature of Coolside waste to design and construct physically stable and environmentally safe landfills. The capacity of various FGD wastes to absorb CO{sub 2} has been recently investigated with the results summarized in the second monthly. The potential usage is for the removal of CO{sub 2} from multi-component gas streams, in particular, natural-gas streams. The third comprises results from ongoing geotechnical testing. The results are concurrent with mineralogical findings that suggest that ettringite, gypsum and calcium-alumino-silicate hydrate phases proceed to form within the aging materials. In specimens with higher degrees of static loading, minerals are forced to grow within available pore space and fractures, which causes less swell. This report also summarizes results from a study of the effects of Coolside leachate on natural clay liners.
