Book Description
The purpose of this Work Plan is to provide a basis and plan for collecting additional required data at the identified sites. The RIs will focus on providing additional information on the presence, extent, and concentrations of certain contaminants in specific areas near the subject AOCs. These data will be compared to previously calculated human health and ecological quantitative risk assessments in technical memoranda for the A4 and A7/A9 AOCs. For the Management-of-Migration OU at AOCs A7/A9, the data will also be incorporated as appropriate in an addendum to the current Feasibility Study (FS) (OHM, May 1995). Additional 551 field investigations will be conducted at SAs P20, P22, and P59. The collection of additional data is not required for SAS P1, P4, P17, P35, and P60. All available data for each SA will be evaluated along with the previously acquired data for each SA in recommending: 1) no further action (NFA); 2) a removal action; 3) inclusion in a facility-wide arsenic investigation; or 4) a remedial investigation (RI). Human health and ecological preliminary risk evaluations (PREs) will be performed as part of the SSIs for all eight SAs. The planned RI data-gap investigations and SSIs will consist of field observations and measurements, the collection of environmental samples, and chemical analysis of the samples.

Book Description
The U.S. Army Environmental Center (USAEC) directed ABB Environmental Services, Inc. (ABB-ES), under Contract No. DAAA15-91-D-0008, to collect environmental samples at Fort Devens, Massachusetts to fill data gaps identified during initiation of the Feasibility Study (FS) for Group 1A sites. The Group 1A sites include the Shepley's Hill Landfill and Cold Spring Brook Landfill at Fort Devens. This Remedial Investigation (RI) Addendum report summarizes the supplemental field investigations, presents the data obtained, and updates the baseline risk assessment prepared for the RI report. Field investigation programs were conducted between September 1992 and July 1993 and included collecting and analyzing of sediment core samples from Plow Shop and Cold Spring Brook ponds, collecting and analyzing fish tissue samples from these two ponds, and conducting a macroinvertebrate study of the two ponds. In addition, several new monitoring wells were installed and groundwater samples were collected for analysis from 27 monitoring wells at Shepley's Hill Landfill and from 10 monitoring wells at Cold Spring Brook Landfill. Soil, sediment, and groundwater samples were also collected from several other areas, including Nonacoicus Brook Wetland and Grove Pond adjacent to Shepley's Hill Landfill, and the Magazine Area adjacent to Cold Spring Brook Landfill.
