i <br /> KLEINFELDER <br /> 4.2.1 Qualitative Field Screenin�� <br /> To provide a qualitative indication of the presence of volatile organic constituents in the soil and <br /> to monitor the constituent concentrations in.the breathing zone, a portable organic vapor analyzer <br /> was used to screen the samples in the fieid. The plhotovac Micro-Fipo photo-ionization detector <br /> (PID) was used to measure total ionizable compounds in parts per million by volume (ppmv) of <br /> vapor. <br /> Soil samples obtained Nacre screened in the field. and the 11,I1) readings were recorded on the <br /> boring logs. No odors or discoloration were noted in soil samples collected during advancement <br /> of soil borings 13-1 throu, h 13-4. PID readings for the samples collected I-anged from 2.4 to 103 <br /> ppti3v. <br /> 4.2.2 Sample 1-landlin�* <br /> After collection. the soil samples were labeled, logged on a chain-of-custody, and immediately <br /> L+ stored in an iced cooler. The samples %were transported and transferred under chain of custody <br /> control to Kleinl-elder's off-ice acid then transported by courier in a sealed container to Sequoia <br /> Analytical of Sacramento- California (Sequoia) for chemical analyses. Sequoia is certified by the <br /> LCalifornia Department of Health (D1-1S) to perform the requested analyses. <br /> 20-2864-02.L'0312019R032 Pace 7 of 12 <br /> ri inno i i,.: r..i,i i,..• Januann, lit, 1999 <br />
