There is some concern that mercury (Hg) in coal combustion by-products can be emitted into the environment during processing to other products, by volatilization or by dissolution into groundwater. This perception may limit the opportunities to use coal combustion by-products after disposal in recycle/reuse applications. In this program, CONSOL Energy Inc., Research & Development (CONSOL) is conducting a comprehensive sampling and analytical program to address this concern. The objective is to evaluate the potential for Hg emissions by leaching or volatilization, and to provide data that will allow a scientific assessment of the issue. The main activities for this quarter were: the re-volatilization study was continued; the literature review was updated; and the ground water study was continued
