pr <br /> r a <br /> f <br /> The proposed ground water remodiatinn syr�tem will consist of <br /> the following items: <br /> 1. Recovery well (monitoring well Mld-5) . Per monitoring <br /> well construction records (Kaprealian, 1987) , Wd was <br /> completed to a depth of 20 loot below ofa4etaih feet <br /> 0.020-inch ©lotted screen from dee <br /> thsbelow grade. Since the wat. ctededrawdown l is rofi2.5efeet <br /> 5 fact <br /> ewollgrade, <br /> allow the pump to be positioned <br /> at 1 9P above the bottom of the well to prevent <br /> sufficiently pumping rate of <br /> intrusion of solids into the pump- <br /> intrusion <br /> p P g <br /> approximately 1 gpm or less will be maintadrncarbon order <br /> to prevent capture <br /> ionosite•Of the by <br /> plume from the adjacent <br /> and lateral piping connecting <br /> 2.

An above ground treatment system, <br /> to include: <br /> a. Microprocessor for system timing and sequencing. <br /> b. 'rwo carbon canisters. Based on an assume average <br /> influent TPH-G concentration of tion capacity of <br /> of 1 gpm, and a carbon adsorp <br /> 6 pounds of hydrocarbons per 100 pounds of carbon, <br /> approximately 20pounds of carbon will be expended <br /> per month initially. Higher TPH-G concentrations <br /> are likely if significant quantities of free <br /> Product are drawn into the recovery well or if an <br /> ver <br /> increase in flow rate is neCXoast. atelyh1,200rpounds <br /> carbon canisters will be aFP of carbon <br /> each to minimize the frequency <br /> replacement. <br /> C. one oil/water separator t:auk and one 250-gallon <br /> double-walled, above ground product <br /> tank. tp are <br /> ground tanks of up tp ve <br /> a 1,100 gallonthe <br /> permitted in Trecy per Section 3- 1.104 of all nror <br /> ISMof Tracy Fire Cede, t requiredstofa 250 be permgallon <br /> tted per <br />. _---- _ -- ----_- less_ capacity r..e not req - <br /> - - - - regulations. <br /> Rule 202.B.5.i-of the-S,7CAPCA <br /> d.
