"This study documents the technical, cost, and environmental factors involved in sludge disposal on dedicated land (DLD). Three general types of DLD operations were identified based on cadmium and nutrient loadings to the land. Six sludge disposal sites (two of each general type) were analyzed. Site visits and existing data were used to determine the relative environmental impacts and costs for the three types of municipal sludge application to DLD sites. Study results indicate that well managed and properly used DLD sites are environmentally acceptable even at high sludge application rates. Cost advantages for any of the three types of sites are difficult to determine, however, because costs are dictated by local conditions and institutional, social, political, and aesthetic factors." |
