' Adsorbed Diesel/Motor Oil Mass-Volume Calculations <br /> PACIFIC PRIDE - WEST LANE <br />' 3230 North West Lane, Stockton CA <br /> Assumptions <br /> 1 Utilizing Figures 7, 10 and 13, the mass distribution of diesel/motor-oil concentrations on the site can be <br /> approximated utilizing the equation for a half-cylinder, a half-cone shape can be used for area no 3 <br /> 1 The volume for ahalf-cylinder can be calculated by the formula <br />' V,,,,d,=(zr rah)/2, where `r' is the radius of the cylinder, `h'is the height of the cylinder <br /> For the estimated cylinder shape of area no 1 r = 5 ft and h r 5 ft <br />' For the estimated cylinder shape of area no 2 r � 42 ft and h z 7 ft <br />' The volume for a half-cone shape can be calculated by the formula <br /> Vw..=(1/3 7r r'h)/2,where `r' is the radius of the cone, `h' is the height of the cone <br />' For the estimated cone shape of area no 3 r z 30 ft and h z 13 ft <br /> The average of TPH-d/mo concentrations were utilized for mass-volume calculations for areas 1,2 and 3,the average <br /> was calculated by summing the detected TPH-d/mo concentrations for each TPH-d/mo-impacted area and dividing by <br /> the total number of detections The average TPH-d/mo concentration for area no I was calculated to be 110 milligrams <br /> per kilogram(mg/kg), 18 mg/kg for area no 2 and 62 mg/kg for area no 3 <br /> DIESELIMOTOR OIL-IMPACTED AREA NO 1) Approximate volume of diesellmo-impacted soil(VD,,O i) <br /> Vn/mo s =(3 14)(5 ft)Z(5 ft)/2 -4 196 ft' (1yd'/27fi') z 7 26 yd' <br /> Converting 7 26 yd3 to cm3(1 e lyd'=764,555cm3)yields approximately 5,550,669 cm3 Using 1 9 g/cm3 as the weight <br /> of soil, the total weight of contaminated soil is approximately 10,546,271 g <br /> IUsing 110 mg/kg as the"average"concentration in the TPH-d/mo area of impacted soil, the mass is calculated to be <br /> weight of soil •average concentration --! 10,546,271 g • 0 000110= 1,160 g of diesel/motor oil <br /> Converting grams of diesel/motor oil to volume of diesel/motor oil(gallons)using density of diesel/motor oil equal to <br /> 0 84 (estimate) <br /> 1,160 g of diesel/motor oil—0 84 g/cm3= 1,381 cm' <br /> 1,381 cm' - (I gallon—3,785 cm3) = 0 37 gallons of diesel/motor oil <br /> Converting gallons of diesel/motor oil to pounds of diesel/motor oil yields <br /> I0 37 gallons of diesel—0 16 gal(estimate)of diesel/lbs of gas = 2 31 pounds of diesel <br /> IAdvanced GeoEnvironniental,Inc <br /> I <br /> I <br />
