Comprehensive analysis of migration pathways (CAMP): Contaminant migration pathways at confined dredged material-disposal facilities. Final report
A confined disposal facility (CDF) is a diked enclosure having either permeable or low-permeable walls that are used to retain dredged material solids. There are two types of CDFs are located within the influence of normal tidal or other water fluctuations. This report identifies and documents key contaminant mobility processes and pathways operative in CDFs under varying operational and environmental conditions. It also summarizes what is known about contaminant migration, cycling, and mobilization pathways, provides information on models and assessment techniques, and identifies areas for which insufficient information is available. The present information does not permit evaluations of the relative significance of contaminant migration pathways from a CDF. Pathways involving movement of large masses of water, such as CDF effluent, leaching through permeable dikes, or leaching through the dredged material, have the greatest potential for moving significant quantities of contaminants out of the CDF. Pathways such as volatilization may also result in movement of substantial amounts of volatile organic contaminants from CDFs. The relative importance of contaminant cycling and mobilization pathways to net mass balance has not been determined, but available information on each of the contaminant migration, cycling, and mobilization pathways is summarized in the report. Where possible, methods have been provided for making rough estimates of contaminant mass movement via pathways.
