LAKE ONTARIO ORDNANCE WORKS
AND MANAGEMENT SERVICES
U.S. Army Corps of Engineers
Niagara Falls, New York
EA is performing a comprehensive remedial investigation and management services for the U.S. Army Corps of Engineers at the former Lake Ontario Ordnance Works (LOOW), a 7,500-acre Department of Defense (DoD) Formerly Used Defense Site constructed in 1940, to produce 2,4,6-trinitrotoluene (TNT). Subsequent to closing in 1942, the LOOW acreage was utilized by various other DoD facilities for production of high-efficiency borane fuels, storage of incendiaries and chemical warfare materiel, a NIKE missile base, and storage of radioactive waste material from the early stages of the Nation’s atomic energy program. EA has assessed over 40 areas of concern from former DoD processes and disposal areas and over 30,000 feet of underground waste and process lines used to support the former facilities. EA self-performed historical photographic analyses; geophysical investigations; onsite quantitative analyses of explosives, volatile organic compounds, semivolatile organic compounds, and polychlorinated biphenyls; TNT awareness and recognition training and onsite TNT screening; radiological monitoring and equipment clearance; and incidental asbestos abatements and interim removal actions.
EA concurrently managed multiple subcontractors, including drillers, union operators, and laborers; analytical laboratories; industrial hygiene laboratories; and data validators during installation of over 2,000 soil borings and 200 test pit excavations for collection of 4,000 environmental samples. Sample matrices included soil, sediment, surface water, groundwater, air, and sludge and wastewater (from within underground waste lines).
Analytical data, as well as historical photographs, as-built drawings, sensitive habitat maps, and tax parcel and ownership information, have been maintained in a database and Geographic Information System that have been invaluable in the development of materials for conducting public meetings and outreach sessions for the client. EA has utilized images from the GIS to prepare presentations, develop fact sheets and handout packages, and prepare static displays at numerous client outreach sessions where EA representatives delivered the presentation and particpated in roundtable question and answer sessions.
EA is currently developing a management plan demonstrating the strategy, milestones, and proposed schedule for regulatory closeout of every parcel within the 7,500-acre Formerly Used Defense Site.
