3.2 Hydrocarbon Impacted Groundwater <br /> 3.2.1 Proposed Inoculation <br /> In an addendum to the FRP (October 5, 1993), GeoAudrt stated that MW-7, MW-8, MW-9, <br /> MW-14 and EW-1 would be used for inoculation of the groundwater However, because <br /> additional data on the groundwater plume has been collected since October of 1993, we <br /> propose the following changes to the groundwater inoculation <br /> GeoAudit proposes to inject a total of 500 gallons of inoculum into MW-8, MW-9, MW-11, <br /> P P ] <br /> MW-14 and EW-1 Approximately 100 gallons of inoculum will be infected into each well <br /> The inoculum will be injected immediately above the piezometnc surface using packers This <br /> will allow for slower infection into the groundwater and should provide a greater plane of <br /> inoculation into the groundwater <br /> Depending upon data collected during the July 1994 monitoring, MW-12 and MW-13 may <br /> also receive inoculum if these wells, or any future wells, are to be inoculated, the <br /> CVRWQCB will be notified in wnting prior to any proposed inoculation <br /> 1 3.2.2 Groundwater Flow Rate <br /> 1 A theoretical flow rate can be calculated using data collected by PES Environmental during <br /> a pump test on EW-1 PES calculated the transmissivity, T, to be between 30 and 40 ft'/day <br /> L To calculate hydraulic conductivity, K, the following equation is used <br /> r <br /> T = KY <br /> where Y is the thickness of the saturated unit Using a transmissivity of 40 and estimating <br /> Y at 25, <br /> T 40 W/day <br /> IK = --- — ------------ = 16 ft/day <br /> Y 25 ft <br /> then, intrinsic permeability can be calculated using the equation <br /> kp = K <br /> I where k is the intrinsic permeability and p is the porosity Using a porosity of 35 percent, <br /> 1 <br /> 4 137G.+-6toltrAS9 <br /> I <br />
