and be responsible for the safe operation of equipment provided and used by Aquatic Environments, Inc.

employees. He will provide technical assistance in using the Aquamog to distribute and mix AC and

sediment through rotovation onto the demonstration plot.

Mr. Mark Fleri will represent Compass Environmental, Inc. (CEI) and serve as Mixing Technology B

Leader. H will be responsible for the mobilization, storage, operation, and demobilization of its patented

rake injector and other equipment necessary to support the injection of a dose of carbon in the upper one

foot of tidal zone sediments at Hunters Point. He will supervise and be responsible for the safe operation

of equipment provided and used by CEI’s employees.

Ms. Sarah Brennan is the Database Manager at BDO should the decision be made to analyze the archived

sample splits. She is responsible for ensuring that the database construction and output meet the needs of

the ESTCP DP for analysis and report preparation. She is responsible for overseeing accurate and

complete loading of data to the database, sample tracking, and providing sample identification codes. She

provides database exports to the Navy contractor validation firm for data validation upon request.

Dr. Carole-Sue Peven is the Chemistry Laboratory Leader at BDO should the decision be made to analyze

the archived sample splits. She is responsible for ensuring that appropriate and comparable technical

procedures for sample analysis are used by BDO. She will coordinate with the Project Manager and

appropriate labs to ensure that holding times are met and that reporting schedules are not compromised

for the archived sample splits. Ms. Peven ensures that the status of laboratory analyses and potential

problems are reported to the Project Manager. She is responsible for performing a management review of

analytical data reports produced.

The field sampling crew is responsible for conducting all field activities according to the QAPP and for

communicating problems to the Project Manager.

All critical data from the archived sample splits that may be used in the HPS FS will be generated by

BDO. BDO is responsible for conducting all analytical activities according to Naval Facilities

Engineering Service Center (NFESC, 1999), the Department of Defense (DoD) Quality Systems Manual

(QSM) for Environmental Laboratories (DoD, 2002), and the QAPP.

A.2.2 Problem Definition/Background

Contaminated sediments pose challenging cleanup and management problems. Hydrophobic organic

compounds such as PCBs associate with fine-grained, organic-rich, sediment material. This serves as a

contaminant reservoir in shallow estuarine and coastal regions from which fish and bottom-dwelling

organisms accumulate toxic compounds that may be passed up the food chain. However, work at Stanford

University and elsewhere proposes that hydrophobic organic contaminants in sediment may be of more or

less concern depending on how weakly or strongly they are sorbed to sediment organic matter (e.g.,

Bucheli and Gustafsson, 2001).

Portions of the offshore sediment at HPS have elevated concentrations of PCBs that could pose a poten-

tial human health and ecological risk. Currently the standard approach to addressing contaminated marine

“mud flat” sediments is the expensive ex situ process of dredging and disposal. Previous laboratory

experiments (Ghosh et al., 2003b; Luthy et al., 2004; Millward et al., 2004; Zimmerman et al., 2004) have

shown that large reductions in PCB aqueous concentrations and PCB bioaccumulation (clams,

polychaetes, and crustaceans) occurred in HPS sediment treated with AC. Based on these observations,

this project will entail mixing AC into sediment as a new technology for contaminated sediment

management.
