Introduction

This report deals with the chemicals of concern (COC) for two units of the Colonial National Historical Park, Jamestown and Yorktown. The chemical contributions present in the James and York River are also discussed as they relate to potential impacts on wildlife populations. Sampling recommendations are based on the ecosystems within the park and the specific baseline inventory of COCs both within and outside the boundaries of the park units. Contaminant data has been reviewed from State, County, U.S. Environmental Protection Agency (USEPA), National Park Service (NPS), Virginia Institute of Marine Sciences (VIMS), U.S. Navy and National Oceanographic and Atmospheric Administration (NOAA) to prepare the data synthesis for this park. Within the Appendix are the NOAA raw data tables along with EPA REMAP data, Virginia Department of Environmental Quality Data, and data from VIMS that have been formatted to simplify examining the chemicals analyzed and their corresponding concentrations. Telephone and survey interviews, along with site visits, were conducted with NPS staff. Based on the recommended monitoring plans, the NPS staff will be able to assess threats to natural resources and whether the “vital signs” are improving or declining within the park boundaries over time as it relates to COCs.

Detailed Standard Operating Procedures for the methods of collection for different matrices, specific analytical methods for different analytes, holding times and decontamination approaches are described in a separate portion of this document (Appendix 1). A detailed description of how to use a simple Hazard Quotient (HQ) approach and a more sophisticated foodweb model for ecological based risk assessment (Sample 1996) is also presented in Appendix 1.
