RThe 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.

The requirements set forth in 29 CFR 1910.120(f), shall be met for all employees performing or supervising hazardous waste operations. Medical exams shall be conducted as soon as possible upon notification by an employee that he/she has developed signs or symptoms indicating possible health hazards or overexposure to hazardous substances. Subcontractor personnel shall provide documentation of current status of participation in a medical surveillance program as required by 29 CFR 1910.120(f). Subcontractors unable to provide such documentation shall have successfully completed a medical examination as described in the above referenced OSHA standard prior to beginning work in a contaminated zone. Specific protocols for medical examinations are designed by an occupational physician. Common components include: (a) medical history and physical examination; (b) dipstick urinalysis, vision screen and vital signs; (c) spirometry ;(d) audiometry; (e) blood chemistry (complete blood count, liver function, kidney function, lipid metabolism, carbohydrate metabolism); (f) resting EkG (with approval); (g) chest radiograph (P/A). No project-specific medical examinations, or biological monitoring is required for this project.
