Proposed investigative activities for the sites identified at the Sudbury Annex (the Annex) were determined through a review of previous activities and findings, and are governed by the established Scope of Work (SOW). The objectives of the activities were to determine whether any contamination exists in groundwater, surface water, sediment, or surface/subsurface soils at the assigned Phase II sites, and, in the cases where contamination is thought or known to exist, to confirm and better characterize its nature and extent. To evaluate each site, and to develop a better understanding of the site's impact on the Annex environment, the Annex has been divided into seven distinct watersheds. In this report, general findings of the field effort are first summarized for each watershed as a whole. Detailed information about activities undertaken and sampling results is then provided for each site. Conclusions and recommendations are reviewed and discussed in conjunction with the findings of the Phase I investigation conducted by OHM Remediation Services Corporation (OHM). Data results are presented with each site investigation (SI) section. The methodology used in the screening of analytical results generated through this Phase II SI, and the screening values used to identify areas of possible concern, are fully explained in Section 7, Volume 1 of this report. The appendices provide field reports, special studies and quality assurance/quality control (QA/QC) results used throughout this report to support the information presented in the text.
