TEMPORAL GEOPHYSICAL SIGNATURES DUE TO CONTAMINANT SOURCE REDUCT...

Geophysical surveys acquired over a ten year period are used to document changes in bulk electrical conductivity associated with the attenuation of hydrocarbon contaminants at the former fire training facility (FT-02) Wurtsmith Air Force base (WAFB), Oscoda, MI, USA.

Initial investigations at the site in 1996 showed that known areas of contamination were characterized by higher bulk electrical conductivity, positive self potential (SP) anomalies, and attenuated ground penetrating radar (GPR) reflections.

The geophysical signatures were attributed to the intrinsic bioremediation...
