Predicted versus measured TCE concentrations at vapor extraction wells for EVS maximum soil concentrations in source area #10 (predicted concentration shown in blue and measured concentration shown in red).March 2003 5-83 OU 12 Demonstration ReportFinal
The effects of changing the permeability field on the predicted TCE concentration profile for the vaporphase is shown in Figure 5-54 for U12-VP1 and source area 1, and U12-VP2 and source area 7. As thepermeability is decreased, the response to increased blower pressure (vacuum) is accentuated.Based on the preliminary results of the sequential forward modeling, there does not appear to be aseparate immiscible TCE phase present in the investigative area at OU 12. The major contaminationappears to be associated with a sorbed fraction and probably a separate LNAPL phase identified duringthe Wireline CPT soil investigation. It is surmised that the major source of TCE contamination is locatedin the upper portion of the vadose zone (20 to 35 feet bgs) offset to the east between U12-VP1 and U12-VP2. This is supported by the results of the TCE soil model developed during the soil investigation.March 2003 5-84 OU 12 Demonstration ReportFinal
