Physical Setting and Historical Information

• Includes Photo-Identified (PI) sites 9 and 13I f ti di th it hi t i• Information regarding the site histories comes from interviews and aerial photographsphotographs

• PI 9– Potentially used for munitions storage and

disposal

PI 13• PI 13– Potentially used as a firing point from which

rocket related ordnance was launched to the Live

3

rocket-related ordnance was launched to the Live Impact Area (LIA) and Surface Impact Area (SIA)

Site Use• PI 9

– Unlikely to have been used for munitionsUnlikely to have been used for munitions disposal and long-term storage

– Likely used as staging area for transporting munitions to the Eastern Maneuver area

– Debris present is likely the result of inadvertent and/or minor discarding of empty casingsand/or minor discarding of empty casings

• PI 13Unlikely to have been used as a firing point due– Unlikely to have been used as a firing point due to site location relative to public areas and Camp Garcia

4

Findings to Date• No unexploded ordnance found on UXO 15

– 5 debris piles consisting mainly of metallic debris5 debris piles consisting mainly of metallic debris, munitions debris, wood, concrete, miscellaneous trashS l th i l t d f iti l t d– Several other isolated areas of non-munitions-related scrap metal and munitions debris

– Several munitions debris (empty casings) just offshore that have been incorporated into the reef

– One small arms item (50-caliber projectile)

A i l t t id tifi d t• Aerial magnetometer survey identified two magnetic anomaly areas within PI 9 and PI 13Sit i it h f d id f fi i

• Site visits have found no evidence of a firing point at PI 13

Study Approach• Remove the debris piles and isolated munitions

debris (potential sources of contamination)debris (potential sources of contamination)• Collect soil samples beneath the debris piles to

determine if contaminant releases have occurred• Perform digital geophysical mapping (DGM) in

the magnetic anomaly areas to determine if there g yare subsurface objects present

• Excavate subsurface objects to determine if there are munitions or explosives of concern (MEC) present

6

• Remove any man-made objects and collect additional soil samples if MEC is identified
