CAP Addendum:Former Fue ng Station, 7500 West Eleventh Street, Tracy, Page 20 <br /> centerline of West Eleventh Street, SJC has taken a very much more conservative <br /> approach for the design of the extraction system to be developed on the north side of <br /> West Eleventh Street. We propose to pump 10,000 gallons of LNAPL and highly- <br /> contaminated groundwater from the extraction trench, which is five times greater than the <br /> volume extracted from Tank Pit No. 1. Pumping of a large volume of groundwater <br /> affected by dissolved components of fuel hydrocarbons from the subsurface will make a <br /> contribution to conversion of anaerobic groundwater conditions in the area around <br /> Monitoring Well MW-7 to aerobic conditions. However, our primary purpose in electing <br /> to pump a full 10,000 gallons from the extraction trench is to provide comfortable margin <br /> of additional flow through the soil to flush out and remove pockets of floating product <br /> from the subsurface. <br />
