Woodbridge Research Facility Remedial Investigation/Feasibility Study; Remedial Investigation, Volume 1 - Text, Tables, and Figures

摘要

The U.S. Army Woodbridge Research Facility (WRF) was used in the past as a major military communications center and a research and development laboratory where electromagnetic pulse energy was tested on military and other equipment. WRF is presently an inactive facility pursuant to the 1991 Base Realignment and Closure list. Past investigation activities indicate that polychlorinated biphenyl compounds (PCBs) are the primary chemicals of concern. A Remedial Investigation (RI) was performed to evaluate the nature and extent of contamination at WRF. Surface soil, subsurface soil, surface water/sediment, and storm water runoff samples were collected as part of the RI. Groundwater monitoring wells were installed and sampled to evaluate the quality of groundwater at WRF. A conceptual hydrogeologic model was developed using water levels obtained from the monitoring wells. A wetland delineation was performed to map the wetland areas of WRF. Human health and ecological risk assessments were performed to evaluate the potential risk to human and ecological receptors from exposures to chemicals present at WRF.
