Wilson Way <br /> Stockton, CA 95205 <br /> Regarding: MTBE/GRO Impacted Ground Water Treatment System <br /> Manteca, CA <br /> Dear Mr. Cuellar: <br /> Pursuant to your request, we have designed a system to remove <br /> MTBE/ GRO/ DRO impacted ground water with a pump-and-treat <br /> design, for your Manteca CA site. We have utilized the summary <br /> analytical date 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 6 gpm continuous flow <br /> This system is a multi-media system, which contains a combination of <br /> a specialty prepared granular activated carbon (GAG), and Sun Solver <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 silt fouling, 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 to series, and two 1,500 pound capacity SunSolve units in <br /> series after the CAG, which provides for liberal retention time on the <br /> adsorption media for optimum removal of the dissolved contaminants <br /> 3325 E Mrraiomta A~w Sude 121 • Ana6wm +Cdriomia 42606 <br /> 71x/572 6177. 714/57'2-1713 Fax - E-Mail PUREEFFECTOAOLCOM <br /> �1Z 3��1d `Y'Ig9�s 6 �� OE 11�YY <br />
