Investigation Of Ordnance Disposal Sites Using Ground And Aerial Geophysics

Ground and aerial magnetic and electromagnetic geophysical methods were used to<br>investigate ordnance disposal sites at the Rocky Mountain Arsenal near Denver, Colorado,<br>as part of a Remedial Investigation/Feasibility Study. These nonintrusive methods<br>successfully delineated ordnance disposal sites enabling estimates of potentially<br>contaminated volumes of soil. The aerial survey results suggested that large areas could<br>be eliminated from further investigation. These techniques were cost-effective in<br>comparison with conventional investigative approaches.
