Abstract: | The Site Characterization and Analysis Penetrometer System (SCAPS) was used to investigate subsurface petroleum contamination
at Aberdeen Proving Ground, Maryland. The SCAPS is a rapid site-screening tool developed by the Tri-Services (U.S. Army, Navy,
and Air Force) to reduce the cost of installation restoration activities. The system, consisting of a geophysical cone penetrometer
fitted with a laser-induced fluorescence petroleum sensor, is capable of simultaneous, real-time delineation of subsurface
stratigraphy and petroleum contamination. Onsite processing of the SCAPS data allows three-dimensional visualization of both
subsurface stratigraphy and petroleum contaminant distribution. The site investigation described herein successfully identified
three distinct areas of subsurface petroleum contamination caused by leaking underground storage tanks containing No. 2 healing
oil. The SCAPS petroleum sensor response was verified by obtaining 20 soil samples and performing onsite and conventional
laboratory analyses for petroleum contaminants. Verification sample results indicate a strong correlation between the SCAPS
fluorescence data and conventional measures of petroleum contamination. This investigation illustrates the capabilities of
the SCAPS for rapid site characterization.
