摘要

This report documents Phases I and II to evaluate the testing and analysis of upland disposal of dredged material from the Appomattox River, Petersburg, VA. Phase I of this study evaluated the environmental and engineering effect of dredging and placing the Appomattox River sediment in the proposed Puddledock site. Phase II of this study evaluated screening of potential contaminate release to atmosphere and evaluated environmental dredging case studies conducted by the U.S. Army Corps of Engineers. The Phase I testing included physical and chemical characterization of the sediment to support design/management operations decision making and contaminant pathway analysis. Additional analyses using characterization data were performed to predict the behavior of the contaminants in various pathways. Phase 11 testing included tests that predict the potential emission release of volatiles during and after dredging. Physical characterization included a number of geotechnical tests including grain-size analyses, Atterberg limits, soil classification, specific gravity, moisture content, self-weight and standard odometer consolidation, and sedimentation testing. Chemical characterization included bulk sediment chemical analysis, toxicity characteristics leaching procedure (TCLP), and ambient water chemical analysis.
