water carbon units After treatment through the #5 carbon unit the treated water is <br /> discharged into a 22,000 gallon capacity Baker Tank for sampling prior to discharge to <br /> sewer, see section on water treatment <br /> RESULTS OFUARTERLY GROUNDWATER MONITORING <br /> GROUNDWATER GRADIENT AND FLOW DIRECTION <br /> A-ZONE- 1876 AND 1856 COUNTRI'CLUB BOULEVARD <br /> Figure 4A uses the new survey elevations supplied by Morrow Surveying survey dated <br /> September 24, 2004 Figure 4A shows the groundwater elevation gradient and flow <br /> direction (October 20, 2005) determined from depth to water measurements at thirteen <br /> wells associated with the Sanchez Property and the four wells associated with Country <br /> Club Food and Fuel The current groundwater gradient shows a flow direction to the <br /> north and northwest, towards monitor well MW10 (pumping well) at a gradient of 0 0006 <br /> ft/linear ft (Country Club Food & Fuel MW2 to Sanchez MW2) A trough has developed <br /> from Country Club Food and Fuel MW2 to Sanchez MW9A with a low at MW10 <br /> B-ZONE- 1876 FIND 1856 COUNTRY CLUB BOULEVARD <br /> Figure 4B uses the new survey elevations supplied by Morrow Surveying survey dated <br /> September 24, 2004 Figure 4B shows the groundwater elevation gradient and flow <br /> direction (October 20, 2005) determined from depth to water measurements at thirteen <br /> wells associated with the Sanchez Property and the four wells associated with Country <br /> Club Food and Fuel The current groundwater gradient shows a flow direction to the <br /> north and northwest at a gradient of 0 0006 ft/linear ft (Country Club Food & Fuel MW2 <br /> to Sanchez MW2), with a low water basin at excavation well (MW10) <br /> PUMPING FROM MW 10 <br /> Pumping from well MW 10, at a rates of 8 9 and 4 gpm, has created a cone of influence <br /> out to wells MW2, MW3, MW4, MW5, MW6A, MW6B, MW7A, MW7B, MW8A, <br /> MW8B, MW9A, MW9B, Country Club (CC) MW1, CCMW2, CCMW3 and CCMW4, <br /> see charts and Table 3 Reducing the pump rate at MW 10 to 2 gpm decreased the extent <br /> of the cone of influence and affected wells MW2, MW3, MW5, MW6A, MW6B, <br /> MW7A, MW713, MW8A and MW8B No or not measurable effects were observed at <br /> MW9A, MW9B, Country Club wells MWI, MW2, MW3 and MW4 <br /> After completing the last pumping rate tests at 2 gpm (November 29, 2005), placing <br /> 16,787 gallons into the Baker Tank, a sample was obtained and the treated water stored in <br /> 8 Sanchez QM 4"' 2005 <br />
