' YELLOW SUBMARINE <br /> 140 West Harding Way <br /> Stockton, California <br /> PETROLEUM HYDROCARBON IMPACTED SOIL <br /> Volume Calculations <br /> On Site Impacted Soil <br /> The contaminant plume was divided into sections based on points where a sample was <br /> collected and analyzed. The cross sectional area was calculated for each section. Each grid <br /> is 5 feet by 5 feet. A maximum width of 10 feet was assumed for the plume based on nearby <br /> borings. Sections were assumed to be consistent across this width. The actual concentrations <br /> of hydrocarbons would decrease over this distance, therefore, the calculated volume of <br /> petroleum hydrocarbons is expected to be higher than the actual volume. <br /> An average concentration of petroleum hydrocarbons in each section was determined from <br /> sample analysis data. The concentration was multiplied by the weight for each section to <br /> determine the weight of hydrocarbons. <br /> Section Volume Weight Concentration Pounds Gallons <br /> (Grids) Tons Pounds (ppm) Petroleum Petroleum <br /> A 21/2 23.15 60,185 3.32 0.20 0.030 <br /> B 12/3 15.43 40,107 0.025 0.0010 0.0002 <br /> C 3 127.78 72,222 83.21 6.01 0.90 <br /> D 12/3 15.43 40,107 1.2 0.048 0.0072 <br /> E 21/3 21.61 56,173 343.59 19.30 2,89 <br /> F 11/3 12.35 32,099 0 0 0 <br /> G 3/4 6.94 18,056 400 7.22 1.08 <br /> H 11/3 12.35 32,099 4.5 0.14 0.022 <br /> I 2/3 6.17 16,049 1000 16.05 2.40 <br /> 1 11/3 12.35 32,099 824.27 26.46 3.96 <br /> Total161/2 153.56 399,244 188.8 75.37 11.29 <br /> rotal Volume =16.58 grids <br /> 1 grid = 5' x 5' x 10' width <br /> = 250 fl? <br /> 16.58 x 250 <br /> Total Volume = 4145 ft3 <br /> 153.5 cubic yards <br />
