EW-4, EW-5, EW-6, <br /> EW-7, EW-8, EW-9 and EW-10 between 15 October and 07 November 2001 (based on <br /> effluent flow Neter observations between 15 October ani 07 November 200 1) <br />' Data collected from the pump and treat influent and extraction well-head grab ground water <br /> samples were representative of general extracted ground water conditions <br />' One cubic foot of water contains 7 43 gallons conversely, one gallon on oz water <br /> is equivalent to <br /> 0 1.337 cubic -Feet, so the volume of processed water is given by <br /> V= (476,964 gallons)(0 1337 ft=/gal) = 53,770 ft' processed water <br />' Ono gallon of water weighs S 337 lbs /gal at 60'F, so the mass of processed water is given by <br /> Mwn, � (4116,964 gallons)(S 337 lbs/gal) =3,976,449 lies. processed water <br /> Multiplying Uric mass of+.he processed w Iter b;the average MTBE concentration (10-15-01=23FcglL <br /> • and 11-07-01 =20,ug/L avg =21 5 ,u/L; yields the approximate mass of MTBE removed from <br /> processed water <br /> MMlaE = (3,976,4.49 Ibs)(0 0000000215) = 0.08 !bs MT3E <br /> A convcrstion tactor of 0 4536 kgJlb can be used to convert pounds of MTBE to grams c:MTEE <br /> IVM7EE = 0 C lbs MTBE (0 4536 kg/Ib)=36 of MTBE <br /> I <br /> I <br /> IAdvanced GeoEnvironmental,Int. <br /> I <br />
