Over 800 ha of forest vegetation are dead on Blue Mountain at Palmerton, Pennsylvania. The major cause was emissions of Zn, Cd, Cu, Pb, and SO2 from a zinc smelter operating since 1898. In 1985, a research effort was initiated to develop a remedial action program to mitigate the environmental damage. Field plot studies were conducted to determine the feasibility of using mixtures of dewatered municipal sludge and fly ash as amendments to facilitate the establishment of vegetation on the highly contaminated soil. Three mixtures of sludge (S) and fly ash (FA) were evaluated (1S:1FA, 2S, and 3S:1FA). The amendments were applied on 0.4-ha plots in May 1985. Five grass and legume seed mixtures were hydroseeded on subplots for evaluation. In addition, seedlings of 10 tree species and hybrid poplar cuttings were planted on the plots. After two growing seasons, results indicate that all three sludge-fly ash mixtures were successful in facilitating vegetation establishment. |
