CALCULATIONS <br /> Former Beacon Station No 695 <br /> 900 South Cherokee Lane <br /> Lodi, California <br /> Purpose: <br /> To calculate the amount of TPH as gasoline and TPH as diesel removed from the site by soil excavation <br /> Assumptions• <br /> A Soil samples were collected immediately after excavated soils were stockpiled,therefore, volatilization <br /> losses were negligible <br /> A Average density of soil is 2.970 lbm/yd3 or 110 lbm/ft3 <br /> A Density TPH as gasoline = 6.1 lbm/gal at STP <br /> Density TPH as diesel = 6.8 lbm/gal at STP <br /> I <br /> Given: <br /> Excavated soil volume, Vs w 2,641 yds' <br /> STOCEPLL.E SOIL. SAMPLE RESULTS <br /> TPH as Gasoline and TPH as Diesel (mg/kg) <br /> Sample No Date TPH' as Gasoline TPH as Diesel <br /> Soil Stockpile A <br /> S-1 thru S-4 01/13/94 3 3b 34 <br /> S-5 thru S-8 01/13/94 3 Ob 28 <br /> S-9 thru S-12 01/13/94 13b 130 <br /> S-3 thru S-16 01/13/94 4 2b 180 <br /> S-17 thnt S-20 01/13/94 19b 420 <br /> S-21 thru S-24 01/13/94 lob 140` <br /> S-25 thru S-28 01/13/94 18 150 <br /> S-29 thru S-32 01/13/94 140 390 <br /> S-33 thru S-36 01/13/94 89 570 <br /> S-37 thru S-40 01/13/94 500 490 <br /> S-42 thru S-44 01/13/94 360 400 <br /> S-45 01/13/94 300 260 <br /> I <br /> MS002 915 <br />
