Risk Assessment


The risk assessment framework in this report provides a mechanism to discuss biosolids management microbial risk using a common metric for comparison of treatment methods, management alternatives, and to set risk-based standards for microbial contaminants in biosolids. Biosolids producers can use this research to interpret the results and potential health implications of biosolids monitoring data. Treatment plant engineers can evaluate the potential risk-based benefits of making operational changes to existing treatment and/or adding additional treatment processes, and environmental managers can use it to evaluate capital improvements and/or land application site placement issues from a health-based perspective. Regulators at the U.S. EPA can use this framework to develop risk-based regulations parallel to the chemical contaminant rules. Published by WERF. 124 pages. Soft cover and online PDF. (2006)
