Abstract

Monitoring the thermal and hydrologic processes that occur during<br>thermal environmental remediation programs in near real-time provides<br>essential information for controlling the process. Geophysical techniques<br>played a crucial role in process control as well as for characterization during<br>the recent Dynamic Underground Stripping Project demonstration in which<br>several thousand gallons of gasoline were removed from heterogeneous soils<br>both above and below the water table. Dynamic Underground Stripping<br>combines steam injection and electrical heating for thermal enhancement<br>with ground water pumping and vacuum extraction for contaminant<br>removal. These processes produce rapid changes in the subsurface properties,<br>including changes in temperature, fluid saturation, pressure and chemistry.<br>Subsurface imaging methods are used to map the heated zones and control<br>the thermal process.
