Y <br /> CAMBRIA <br /> i <br /> i <br /> The viability of groundwater extraction will be evaluated by measuring flow rates achieved by <br /> pumping from well MW-4 Step discha will be conducted first to evaluate well <br /> efficiency and determine sustainable yield fora constant-rate test A constant-rate est ill be <br /> conducted to evaluate aquifer hydraulics Groundwater drawdown in the extraction well, <br /> adjacent wells, and proposed piezometers will be measured using MimTroll pressure transducers <br /> Recovery rates in the extraction well will similarly be measured Results from the pump test, <br /> groundwater sampling, and quarterly monitoring results will be used to determine whether <br /> additional groundwater remediation is warranted <br /> Report Preparation. Cambria will prepare an aquifer pump test report which will include field <br /> procedures, laboratory results, boring logs, conclusions, and recommendations <br /> The scope of work described in this work plan will be performed under the supervision of a <br /> registered professional engineer or registered geologist <br /> Schedule <br /> . Upon receiving wntten approval of this work plan and our June 5, 2002 Site Investigation Work <br /> Plan from SJCEHD and appropnate dnllmg permits, Cambna will schedule the well and <br /> piezometer installations Once the proposed extraction well and piezometers are installed, <br /> Cambria will initiate the pump test <br /> • <br /> 0955 4 <br />
