• included in Appendix G Based on the analytical results, approximately 112 pounds of hydrocarbon <br /> vapors per hour (lbs/hr) were extracted from VE-1 during the combined test <br /> Data Analysis <br /> Soil vapor extraction (SVE) analysis was conducted on the data from extraction well VE-1 Darcy <br /> Equation analysis for this well, presented on Calculation Sheets F-1 and F-2, indicated an average <br /> soil permeability of 159 x 10"8 cm2 Critical velocity analysis, presented on Calculation Sheet F-3, <br /> indicated that a radial influence of approximately 26 feet was possible at the average flow rates <br /> determined from the SVE testing data <br /> All AS and SVE pilot testing data is summarized in Tables 4 through 7 and the analysis is <br /> summarized in Appendix F <br /> D. RECOMMENDED REMEDIATION TECHNOLOGIES <br /> The results of the air sparging and soil vapor extraction pilot testing indicated these are feasible <br /> treatment technologies for the impacted soil and groundwater at this site The results of the <br /> enhanced bioremediation pilot testing indicated that both oxygen and nutrient augmentation are <br /> • feasible treatment technologies for the impacted soil and groundwater at this site Based on the pilot <br /> testing results, an AS/SVE combination was selected as the best treatment technology for the site <br /> In addition, enhanced bioremediation will also play a role, as oxygen augmentation to the subsurface <br /> occurs from the AS/SVE operations <br /> E. CONCLUSIONS AND RECOMMENDATIONS <br /> Air sparging and soil vapor extraction pilot testing activities were conducted to assist in determining <br /> the hydrologic characteristics at the site and system design parameters <br /> Conclusions <br /> Based on the results of the pilot testing activities, the following conclusions were drawn <br /> • Review of the air sparging data and graphs indicated a radial influence of approximately <br /> 10 feet AS well operating parameters were determined to be approximately 2 to 3 scfm per <br /> well at infection pressures of 3 to 4 psig <br /> • Review of the soil vapor extraction data and graphs indicated a radial influence of <br /> approximately 26 to 30 feet, depending upon the criteria utilized SVE well parameters were <br /> determined to be 39 to 48 scfm per well at vacuums varying from 70 to 92 in w c (injection <br /> pressures of 3 to 4 psig <br /> • The average soil permeability was determined to be 1 59 x 10-8 cm2 <br /> III-6 <br />
