14. ABSTRACT

This manual is a resource document providing technical guidance for evaluation of potential contaminant migration pathways from

confined disposal facilities (CDFs). Disposal of dredged material in CDFs is one of the most commonly considered alternatives for

material deemed unsuitable for conventional open water disposal because of potential contaminant impacts and is also an option

commonly considered for disposal of contaminated sediments dredged for purposes of sediment remediation. If contaminated sediments

are placed in a CDF, consideration of pathways for migration of contaminants from the site and potential contaminant impacts may be

required. A suite of evaluation procedures and laboratory test procedures has been developed to evaluate CDF contaminant pathways

and is presented in detail in this manual. A tiered testing and evaluation approach is used. The Tier I evaluation determines the need for

pathway evaluations, pathways of concern, contaminants of concern, and which pathways require more detailed evaluations based on

existing information. Tier II evaluations consist of determining the need for management actions derived from very conservative

techniques that use the chemical, physical, and biological characteristics of the dredged material and basic information about the CDF.

Tier III focuses primarily on definitive evaluations, including pathway testing. Tier IV, which should rarely be needed for navigation

projects, includes formal quantitative risk assessment designed to answer specific, well-defined questions.
