CAMBRIA <br /> near B-4 can be represented by a cylinder with a diameter of 4 feet and a thickness of 20 feet These <br /> areas are shown on the attached map <br /> Representative Concentrations. An average of all soil samples collected in the former UST area was <br /> used as the representative concentration of the ellipsoid The concentration detected in sample B-4 <br /> at 20 fbg was used as the representative concentration for the entire cylinder near the western <br /> dispenser <br /> WASTE OIL UST AREA <br /> Three soil samples were also collected in the vicinity of the waste oil tank One of these samples <br /> contained 298 ppm TPHg and 0 044 ppm benzene The two other samples from this location did not <br /> contain detectable concentrations of TPHg or benzene,indicating that impact to soil is localized in this <br /> area Therefore, these concentrations were not used to calculate the initial mass of TPHg and benzene <br /> in soil <br />
