Book Description

Site Investigations (SIs) were conducted by ABB Environmental Services, Inc. (ABB-ES) at Fort Devens between May 1992 and January 1994 at twelve Study Areas (SAs) and nineteen historic gas station sites in Groups 2 and 7. As a result of the SI for SA 57 in Group 2, SA 57 was divided into two areas of concern. Area 1 was identified as the storm drain outfall (at Cold Spring Brook) which drained the Building 3713 area. Area 2 was defined as the drainage swale associated with Building 3757, and immediate surrounding area, including a portion of Cold Spring Brook downstream from Area 1. Area 1 has subsequently been included for study under the installation-wide AREES-70 storm water study. Based on the SI findings, and results of a subsequent removal action, a remedial investigation and feasibility study (RI/FS) has been recommended at SA 57/Area 2. This Draft Work Plan provides a history of investigation activities and findings at SA 57, and outlines proposed plans for the RI/FS. In this Work Plan and all subsequent plans and reports, SA 57 will be referred to as Area of Contamination (AOC) 57. ABB-ES will conduct RI and FS activities at AOC 57 in accordance with the plans and rationale presented in the Work Plan and in conformance to the methods, procedures, and requirements set forth in the Final Project Operations Plan (POP) prepared by ABB-ES for activities conducted at Fort Devens.
