Twenty two laboratory lysimeters were monitored for 12 months in an effort to characterize the leaching behavior of dry flue-gas desulfurization wastes generated during tests of the Coolside duct-injection Technology. Included were samples from Ohio Edison`s 1990 demonstration runs conducted at its Edgewater power plant and materials derived from runs conducted in CONSOL`s Coolside pilot plant. The primary objective of the study was to generate predictive information on leaching behavior of Coolside wastes. In addition, the test matrix was designed to examine the impact of various parameters including (1)lysimeter packing density, (2) use of a constant vs rain simulation method of water addition, (3) variation in the extent of prehydration of the wastes prior to loading, and (4) exposure to elevated levels of CO{sub 2} during the study. The relationships between these latter parameters and leachate characteristics are discussed.
