,R "N .,u. M- 10 <br /> a <br /> a <br /> 17 <br /> 4-2 <br /> Extraction Well Pump 'fest. The pump test involves pumping from the extraction <br /> well and monitoring the groundwater depths at the eight existing monitoring wells. <br /> E Mobile Treatment System. A groundwater treatment system will be required for <br /> treatment of the groundwater pumped during the pump test. The groundwater <br /> would be routed to two portable 21,00-gallon tanks connected in series. <br /> Groundwater will be pumped continuously from the storage tanks through a <br /> granulated activated carbon(GAC)adsorption system. <br /> The storage tanks-'allow the pump test to be performed at a higher flow rate than <br /> the maximum flow rate allowed through the GAC adsorption system. We are <br /> pursuing the option of disposing the treated effluent to the Iocal sewer system. A <br /> conceptual schematic of the extraction well and groundwater treatment system is <br /> shown on Figure 1. <br /> 4. . Groundwater Modeling <br /> The aquifer characteristics determined from the extraction well pump test will be <br /> .qs used to model the local effects of the extraction w <br /> ell on the aquifer. inparticular, the modeling will determine the pumping rate necemary to produce a <br /> capture zone that will contain and extract the contaminated groundwater plume. <br /> w The modeling will also determine the reinjection well Pumpingrate and the <br /> influence of Well 12 on the extractijn well. <br /> !vi <br /> �s <br /> f# <br /> d rg <br /> r � iib <br /> g <br /> l} pT - <br />
