Determining Recovery Potential of Dredged Material for Beneficial Use - Soil Separation Concepts

Abstract : This is the first of three technical notes providing guidance in evaluating dredged material recovery potential. This technical note provides an overview of physical separation (soil washing) concepts, and methods for calculating volumes of recoverable material meeting beneficial use (BU) requirements. The other technical notes address data acquisition for volume estimation. The second (Olin-Estes and Palermo 2000) outlines a prescriptive approach, using existing information obtained from limited sampling, to estimate volumes meeting BU requirements. The third (Olin-Estes 2000) introduces statistical methods for developing a more extensive sampling plan, and methods of organizing and interpreting data.
