DIESEL <br /> CALCULATION OF MASS AND VOLUME OF RESIDUAL DIESEL <br /> CHEROKEE SERVICE CENTER, 303 SOUTH CHEROKEE LANE <br /> LODI, CALIFORNIA <br /> Assumptions: <br /> Source of PPCs from product piping at the location of Sample 3. <br /> Attenuation is linear in aany one direction ay from the source <br /> Greatest concentration of PPCs below source at approximate depth of product piping (2 feet BSG). <br /> Shape of the iso concentration lines is an inverted cone of the relative dimensions indicated in Drawing 2. <br /> Analytical results for boring B-1 at 35 feet represent maximum PPC concentrations at 35 feet BSG. <br /> NOTE: Depths measured from below the source at 2 feet BSG <br /> Diesel <br /> Conc.
