1 <br /> ' Mass-Volume Calculation of Dissolved MTBE; 17 April to 22 May 2002 <br /> RAINWATER CAR WASH- 420 West Yosemite Avenue, Manteca CA <br /> Assumptions <br /> ' A total volume of 42,698 gallons was extracted from well EW-1 between 17 April and 22 <br /> May 2002 (based on effluent flow meter observations) <br /> ' Data collected from the pump and treat influent were representative of general extracted <br /> ground water conditions <br /> One cubic Foot of water contains 7 48 gallons, conversely, one gallon of water is equivalent to <br /> 0 1337 cubic feet, so the volume of processed water is given by <br /> ' V= (42,698 gallons)(0 1337 ft/gal) =5,708 ft' processed water <br /> ' One gallon of water weighs 8 337 lbs/gal at 60'F, so the mass of processed water is given by <br /> Mw,T=(42,698 gallons)(8 337 lbs /gall) =355,973 lbs. processed water <br /> Multiplying the mass oFthe processed water by the average MTBE concentration(22,000µgll)yields <br /> the approximate mass of MTBE removed from processed water <br /> ' MMT13F, = (355,973 lbs)(0 000022000) = 07.83 lbs MTBE <br /> ' A converstion Factor of 0 4536 kg/lb can be used to convert pounds of MTBE to kilograms of <br /> MTBE <br /> tMMTBE= 7 83 lbs MTBE(0 4536 kg/lb) =3,552 g of MTBE <br /> 1 <br /> ' Advanced GeoEnvironmental,Inc <br /> E I ' <br />
