ABSTRACT

Biosolids produced during the wastewater treatment process may contain concentrated levels of contaminants originally contained in the wastewater. Any disposal method must take these contaminants into account. In ultimate disposal, the goal must not be to merely shift the original pollutants in the wastestream to a final disposal site where they may become free to contaminate the environment. Effective biosolids disposal involves economically and environmentally sound disposal or reuse that adheres to the EPA's 40 CFR Part 503 Final Rules for Use and Disposal of Sewage Biosolids.
