Acid and toxic abandoned mineland sites provide an opportunity whereby flue gas desulfurization (FGD) by-product can be beneficially used as a reclamation amendment material. Studies are needed to compare the effectiveness of FGD by-product, as compared with resoil, for reclamation purposes. Initial studies provided information about the chemical and physical properties of the FGD by-product and how to transport and blend the FGD by-product with yard waste compost. Greenhouse studies indicated that rates of 125 dry tons/acre of FGD and 50 dry tons/acre of yard waste compost would provide optimum results for reclamation of acid and toxic spoil contained at the Fleming abandoned mineland (AML) site. Their results showed that heavy metal loading rates were much lower using the FGD/compost mixture than using resoil material. Dioxin in the mixture was also less than the 5 ppt level considered as normal background. The technical problems of using FGD by-product for reclamation of an AML site were solved. However, considerable efforts to educate the public about the merits of reclaiming the Fleming AML site using this FGD/compost mixture were required before initiating field reclamation activities. Education efforts must continue if FGD by-products are to achieve general acceptance as a reclamation alternative to resoil in cases where resoil is of scarce supply.
