PAM-err <br /> Rund SUN-AG Environmental Division <br /> 41 < s . P413111 <br /> Reference Quote * SA©SO 1-140 <br /> Mr. Timothy J. Cuellar <br /> Advanced Geoenvironmental Inc. <br /> 4405 N. Wilson Way <br /> Stockton, CA 95205 <br /> Regarding: MTBE/GRQ Impacted Ground Water Treatment System <br /> Manteca, CA <br /> I ©ear Mr. Cuellar; <br /> Pursuant to yopr request, we have designed a system to remove <br /> MTBE/ GRO/ DPO impacted ground water with a purnp-and-treat <br /> design, for your Manteca CA site. We have utilized the summary <br /> analytical data and flow rate data that you provided to us in your fax <br /> of 4-19-2001, utilizing the data for well EW-1 only pursuant to your <br /> direction. The design flow rate is f gpm continuous flow. <br /> This system is a multi-media system, which contains a combfnatlon of <br /> a specialty prepared granular activated carbon (GAC), and Sun Solve, <br /> which is a combination of a specialty prepared granular activated <br /> carbon and a hydroscopic synthesized filter media that has a high <br /> affinity for MTBE. <br /> We recommend that the system Include a settling tank for the <br /> recovered groundwater, a suspended solids pre filter to protect the <br /> media beds from slit fuuiing, appropriate pumps and controls for <br /> system control and a flow meter/totalizer. Based on the discharge <br /> point of the treated water, there may be additional system controls <br /> and/or requirements that need to be incorporated into the system. <br /> This system consists of two 1,,000 pound capacity granular activated <br /> carbon units in series, and two 3,500 pound capacity SunSolve units in <br /> series after the GAC, which provides for liberal retention time on the <br /> adsorption media for optimum removal of the dissolved contaminants. <br /> 3325 F Mires Avenue,5wie 121 •Ana6ftm•Ca&rni t 92806 <br /> ` <br /> 71 d/6724 i 77- 71 A/572-1713 Fax E-Mail PUREEFFECrOAOLCOM <br /> 1 <br />
