<br />' yields 605,879 grams of gas Converting grams of gasoline to volume of gasoline(gallons)using density of gasoline
<br /> to equal 0 75 yields 807,838 cm' Dividing by 3,785 gallons per cm'yields 213 gallons of gasoline
<br /> 3) Approximate volume of petroleum hydrocarbon impacted soil in outer-middle sequence(Vo,,,)
<br /> V,,,,,=(60 ft)(50 ft)(0 7854)(t/=55 ft) 4 64,796 ft' 2,400 yd'
<br /> The volume of the inner-middle sequence(V,,,,) should be subtracted from the overall volume of the outer-middle
<br /> sequence(Vo,,,)
<br />' V,),,=VOM-VIM -4 2,400 yd'.820 yd -4 1580 yd
<br /> T:x volume of the inner middle sequence can be calculated by the method shown above Converting 1580 yd' to cm3
<br />' yields approximately 1,206,412,072 cm3 Using 1 5 g/cm' as the weight of soil,the total weight of contaminated soil
<br /> is approximately 1809618107 g Using 100 ppm as the"average"concentration of gasoline in the outer-middle sequence
<br /> yields 180,962 grams of gas Converting grams of gasoline to volume of gasoline(gallons)using density of gasoline
<br /> to equal 0 75 yields 241,282 cm3 Dividing by 3,785 gallons per cm3 yields 64 gallons of gasoline
<br /> 4) Approxunate volume of petroleum hydrocarbon impacted soil in outer sequence(Vo)
<br /> Vo=(130 ft)(120 ft)(0 7854)('h65 ft) -4 398,198 ft' 14,748 yd'
<br /> The volume of the outer-middle sequence(Vor,) should be subtracted from the overall volume of the outer sequence
<br /> (VI)
<br /> Vo =V 0-VoM -1� 14,748 yd3-2,400 yd' 4 12,348 yd'
<br /> The volume of the inner middle sequence can be calculated by the method shown above Converting 12,348 yd'to cm3
<br /> yields approximately 9,428,339,405 cm3 Using 1 5 g/cm' as the weight of soil,the total weight of contaminated soil
<br />' is approxunately 14,142,509,110 g Using 50 ppm as the"average"concentration of gasoline in the outer sequence
<br /> yields 707,125 grams of gas Converting grams of gasoline to volume of gasoline(gallons)using density of gasoline
<br /> to equal 0 75 yields 942,834 cm' Dividing by 3,785 gallons per cm3 yields 249 gallons of gasoline
<br />' Combining the total volume of gasoline impacted soil yields a grand"total of 14,748 yd'containing an estimated 1,113
<br /> gallons of gasoline
