Stell supports the Department of Defense’s (DoD) initiative to identify any issues with munitions constituents of concern migrating off operational ranges so the DoD can address them before they become a bigger issue threatening human health or the environment and training. We assess military range site characteristics, operations, weapons and munitions usage, and built infrastructure and identify munitions constituents of concern, their potential deposition and transport mechanisms, and their source areas. Our staff evaluates risks to potential human and ecological receptors and recommends further actions or investigations based on results of the assessment.
Operational Range Assessment Program (ORAP), Nationwide (U.S. Air Force)
Stell has provided ORAP support at 14 Air Force bases in the southeastern United States, Alaska, Japan, and Korea. We evaluate the potential for environmental impact associated with operational ranges at each base to meet the Air Force’s goal to “mitigate encroachment and balance environmental stewardship with operational requirement.” Our projects have included qualitative and quantitative assessments, including soil and water sampling, to evaluate munitions constituents migration. We ensure ensured that the methodologies employed are executed consistent with data quality objectives and regulatory standards. Work has been performed in accordance with the DoD and Air Force ORAP guidance.
Site Inspection (SI), Camp Minden, LA (Louisiana Army National Guard)
Stell conducted a Military Munitions Response Program SI to determine if munitions or explosives of concern existed at the sites and if munitions constituents contamination related to former DoD operations are present in shallow soil. The objectives of this work were to determine the potential need for a removal action and collect and develop additional data to characterize the environmental impact to the site and for hazard ranking scoring by the U.S. Environmental Protection Agency.
Unexploded ordnance technicians completed a geophysical survey of the area. We conducted shallow soil sampling in areas where munitions or explosives of concern was identified to characterize the munitions constituents. We expanded and repaired the fence surrounding the site to include munitions and explosives of concern outside the current boundary. We recommended a remedial investigation/feasibility study based on the identified presence and distribution of munitions and explosives of concern at the site.
