�A <br /> 1, H. KLEINFELDER&ASSOCIATES <br /> File: W-2006-1 <br /> December 16, 1985 <br /> Page 8 <br /> of the samples for chemical analyses were based on the <br /> FID readings obtained in the field. These sampler <br /> included one low PFD reading (200 ppmv) from a depth of <br /> 16 feet and a high PID reading (1,200 ppmv) from a depth <br /> of 26 feet in Boring B-1. An additional soil sample from <br /> a depth of 21 feet in Boring B-3 was analyzed for total <br /> hydrocarbons. gable 1 presents the PID readings of the <br /> 14 soil samples collected, and Table 2 presents the <br /> results of the three soil samples chemically analyzed. <br /> - Data obtained from the analytical results and the PID <br /> readings show that gasoline is present in the soil around <br /> the tank excavation. The presence of gasoline was first <br /> indicated from PID readings in the 16 foot sample from <br /> Borings B-1 and 3-3, and the 21 foot sample from B-4. <br /> ' The highest PID readings (up to 1,200 ppmv) were recorded <br /> in Boring B--1 which is located to the east of the tank <br /> excavation. In Borings B-1 and 5-3 the PID reading <br /> increased with depth. No PID readings were recorded from <br /> Boring 5-2 which was drilled approximately 5 feet to the <br /> — east of B-1. The analytical results of the two samples <br /> chemically analyzed from Boring B-1 corresponds to the <br /> PID results from that boring. Total hydrocarbons were <br /> detected at 3,300 ppm in the 26 foot sample with the <br /> highest gasoline related constituents being xylene at 57 <br /> I <br />
