Kelly Williamson <br /> Kayo Oji Company <br /> April 17, 1985 <br /> Page 3 <br /> The total wet weight of the soil , assuming 12 percent moisture content <br /> and then the total dry weight in kilograms, was calculated. The highest <br /> hydrocarbon concentration (sum of xylene, benzene and toluene) for each <br /> site was used to calculate the amount of gasoline in the ground. Assum- <br /> ing a specific weight of approximately 0.8 g/cc for the hydrocarbons and <br /> 998.6 kgm/cubic meter for water at 50°F. , the volume of gasoline in the <br /> soil was calculated. The calculations are recapped below: <br /> (TOTAL VOLUME OF DRY SOIL)*(125 LBS. PER CUBIC FOOT)= <br /> TOTAL UNIT WEIGHT <br /> (TOTAL UNIT WT) (0.454 kgm/lbs) (1/1.12-soil moisture 12%) <br /> TOTAL DRY WEIGHT SOIL <br />. (TOTAL DRY WEIGHT SOIL) (TOTAL HYDROCARBONS IN ppm) _ <br /> TOTAL HYDROCARBONS in mass <br /> (TOTAL HYDROCARBONS IN MASS)/(0.8*998.6) _ <br /> TOTAL HYDROCARBON VOLUME in cubic meters <br /> CONVERT CUBIC METERS TO LITERS OF HYDROCARBONS <br /> (TOTAL HYDROCARBONS in liters) (1/3.78)= <br /> TOTAL HYDROCARBONS in gallons <br /> In addition, calculations were completed and are shown in graphical <br /> form, Plate 1, which show the sensitivity of the final hydrocarbon <br /> volume to the assumed concentration of hydrocarbons (sum of xylene, <br /> benzene and toluene) in the soil . The concentration of hydrocarbons is <br />
