Hunters Point Shipyard Parcel F ESTCP Demonstration Plan

Appendix A: Quality Assurance Project Plan

A.1.0 INTRODUCTION

This Quality Assurance Project Plan (QAPP), which contains the Sampling and Analysis Plan (SAP), has

been developed for the Environmental Security Technology Certification Program (ESTCP)

Demonstration Plan (DP) prepared by Stanford. The original proposal to ESTCP was titled Field Testing

of Activated Carbon Mixing and In Situ Stabilization of PCBs in Sediment. The ESTCP DP will be

completed at Hunters Point Shipyard (HPS) Parcel F (offshore sediment) in San Francisco, California.

In recent Strategic Environmental Research Development Program (SERDP)-funded work with sediment

from Hunters Point, San Francisco Bay, Dr. Richard G. Luthy’s research group at Stanford found that the

polychlorinated biphenyls (PCBs) in the sediment tend to preferentially accumulate in coal-derived and

char particles where the compounds may be strongly bound (Ghosh et al., 2003a; Luthy et al., 2004

Zimmerman et al., 2004). In addition, the Stanford team, along with researchers at the United States

Army Corps of Engineers Engineering Research Development Center (USACE-ERDC), demonstrated in

laboratory experiments that large reductions in PCB aqueous concentrations and PCB bioaccumulation

(clams, polychaetes, and crustaceans) occurred in Hunters Point sediment treated with activated carbon

(AC) (Ghosh et al., 2003b; Luthy et al., 2004; Millward et al., 2004; Zimmerman et al., 2004). These

observations suggest that mixing AC into sediment may provide a new technology for contaminated

sediment management.

This QAPP describes the ESTCP DP that will be conducted during FY2005-2007. The overall purpose of

this project is to demonstrate that AC sorbent mixed with sediment is a cost-effective, in situ, non-

removal, management strategy for reducing the bioavailability of PCBs in offshore sediments at HPS site.

The scope of the ESTCP DP is to:

1) Demonstrate and compare the effectiveness, in terms of AC application and ease of use, of two

available large-scale mixing technologies,

2) Demonstrate that AC treatment reduces PCB bioaccumulation results in field tests, and

3) Demonstrate no significant sediment resuspension and PCB release after the large-scale mixing

technologies are used.

This QAPP documents the policies, the project organization, quality assurance (QA) requirements, and

quality control (QC) procedures to be implemented for the ESTCP DP to ensure that the data are valid for

use. The QAPP is incorporated as Appendix A to the ESTCP Demonstration Plan, and is not an

independent document. This QAPP addresses all U.S. Environmental Protection Agency (U.S. EPA)

requirements for a quality assurance project plan (QAPP) (U.S. EPA, 2001) with the elements of a field

sampling and analysis plan (SAP) so that field and laboratory activities are described in one document. It

defines the QA/QC methods that must be implemented to ensure that data meets the requirements of the

Data Quality Objectives (DQO). The Health and Safety Plan in Appendix B, which is issued as a separate

document, defines the preventative and prophylactic procedures that will be implemented during the field

survey to ensure the safety of the field team.

The Navy has indicated that the AC treatment technology is being considered as an alternative for

detailed analysis in an upcoming Feasibility Study (FS). Any data that the Navy may use to make a

decision about assessing the AC treatment technology in the FS must be generated by a Navy-certified

lab. Since the laboratories at Stanford, University of Maryland Baltimore County (UMBC), and USACE-

ERDC that are involved in this ESTCP DP are not Navy-certified laboratories, The Navy Remedial

Project Manager (RPM) of the HPS Parcel F site has requested that an archive of sample splits be created

for the clams and amphipods that are collected to assess the AC treatment effects on PCB

bioaccumulation. These samples splits will be analyzed by Battelle Duxbury Operations (BDO), a Navy-

certified laboratory. The resulting PCB bioaccumulation data from BDO has been identified by the Navy
