10.4 Treatment of Dredged Material Solids

10.4 Treatment of Dredged Material Solids

Various treatment processes have been investigated for dredged material

treatment, including biological, chemical, extraction, immobilization, and thermal

processes. Dredged material may be treated at a temporary rehandling facility,

with the treated material subsequently transported to an ultimate disposal facility.

Treatment can also be considered for a smaller portion of the total volume of

material to create stabilized material for use in constructing liners, covers, etc.

A variety of process options are potentially available for each type of

technology; however, prior to recent demonstration programs and Superfund

cleanups, only a limited number of treatment technologies had actually been

applied on a pilot scale or full scale. The base of experience for treatment of

contaminated sediment is still very limited.

10.5 Guidance for CDF Management Actions

Guidance for design, construction, and operation of CDF contaminant

controls is available in Engineer Manual 1110-2-5027 (HQUSACE 1987),

USACE Environmental Effects of Dredging Programs (EEDP) technical notes

(http://www.wes.army.mil/el/dots/eedptn.html), and USACE Dredging Operations

and Environmental Research (DOER) technical notes (http://www.wes.army.mil/

el/dots/doer/technote.html). EPA guidance on control measures is also available

(USEPA 1994). All available information on CDF controls is also being

incorporated in a combined Engineer Manual 1110-2-5028, Dredging and

Dredged Material Management (HQUSACE in preparation), which is to be

published on the internet and periodically updated. These references contain

testing procedures and criteria needed for evaluating and selecting appropriate

contaminant control measures for CDFs and should be consulted for additional

detailed discussions of the attributes of the various technologies.
