Abstract
The report describes progress made during the first two years of a field evaluation of treated and untreated ponding techniques for the disposal of power plant flue gas desulfurization sludges. The evaluation used two 10 MW lime and limestone flue gas scrubbers of TVA's Shawnee Power Station, Paducah, Kentucky. Results indicate that the concentration of total dissolved solids (TDS) in the leachate of treated ponds was maximum immediately after filling, or within a few months, and was approximately half that of the input liquors. Leachate from untreated ponds was similar, except that the maximum was approximately the same as the TDS of the input liquor. After 2 years, TDS in the leachates of all ponds are between 33% and 50% of that of their respective input liquors. Leachates from the evaluation ponds exhibit decreasing concentrations of chloride ion, and the TDS have stabilized at approximately gypsum saturation. Trace elements exhibited little change. Chemically treated sludges continue to exhibit good landfill strength and generally reduce the mass release of sludge constituents to the subsoil by at least 2 orders of magnitude.

Contents Notes
This report describes the progress made during the first two years (Septembre 1974 through October 1976) of a field evaluation project being conducted by the U.S. Environmental Protection Agency (EPA to assess techniques for the disposal of power plant flue gas desulfurization (FGD) sludges. The evaluation site is at the Tennessee Valley Authority Shawnee Power Station in Paducah, Kentucky. Two 10-MW prototype flue gas scrubbres, using lime and limestone, produced sludges that were placed in six test ponds. Three contain untreated sludges; each of the three remaining ponds contains sludges chemcially treated by one of three commercial contractors. Test samples of treated and untreated sludges, groundwater, supernate, leachate, and soil cores are being analyzed. Results to date indicate that the maximum concentration of total dissolved solids (TDS) in the leachate of treated ponds occured immediately after filling, or within a few months, and was approximately half that of the input liquors. Leachate from untreated ponds followed asimilar pattern, except the maximum concentrations were approximately the same as the TDS of the input liquor.
