ABSTRACT
The treatment of wastewater from modern urban society produces a rich resource: biosolids. Some eight million dry metric tons of biosolids are produced annually in the United States in 1995, a significant growth from the five million tons generated in 1990 [1]. Of the technologies currently available to use this natural resource, the most direct and most commonly employed is land application-the term used to describe the application of biosolids to land for purposes of agricultural production, production of other non-agricultural crops (e.g., forest application) or use as a soil amendment/fertilizer to reclaim areas which have been disturbed by mining or other activities.
