Heterogenous Wastes Characterization Methods and Recommendations addresses the problems faced by investigators when attempting to characterize heterogenous wastes contaminated with hazardous chemicals and/or radionuclides. The book is the result of a workshop conducted by the U.S. Environmental Protection Agency and the U.S. Department of Energy to devise methods for cleaning up waste sites, including landfills and drum dumps, where these chemicals have been spilled or improperly stored. The book summarizes study planning tools, sampling design strategies, and field and laboratory methods now in use. It also identifies the advantages and disadvantages of each method. In addition, the book identifies areas that would benefit from methodological research or development or the adoption of new approaches. Pertinent regulatory definitions have been assembled and augmented with practical working definitions. Heterogenous Wastes Characterization Methods and Recommendations is essential for personnel who work with hazardous wastes or in sanitary engineering firms.
