KLEINFELDEB I <br /> �. Each sample collected was screened in the Geld, and the PID reading was recorded on the <br /> boring log (Plate f). No concentrations of ionizable compounds were indicated in the six <br /> samples screened. It should be noted that the PID provides a qualitative indication of <br /> contarnination and does not identify or provide a concentration of a specific contaminant. <br /> Based on the qualitative field screening, one or more soil samples are submitted for <br /> Chemical analysis to provide a confirmation quantitative assessment. <br /> For the protection of the Geld crew, the PID was also used to measure the total volatile <br /> concentrations in the breathing zone prior to and during the drilling of the borings. No <br /> - volatile concentrations were detected above 1 ppmv in the breathing zone. <br /> 113-88-908 8 <br />
