APPENDIX B<br />

If instrument blanks indicate there is contaminant carryover in the GC, the GC will be decontaminated<br />

using heat, ambient air, or hydrocarbon-free air. If equipment blanks indicate there is contamination of<br />

the syringe, the syringe will be decontaminated by exposure to heat, replacement of syringe parts, or<br />

replacement of the syringe until the syringe is adequately decontaminated. If equipment blanks indicate<br />

contamination of the probe, the probe will be decontaminated by either wet or dry methods until the<br />

probe is adequately decontaminated.<br />

Data Reporting<br />

The results of the soil gas survey are used to qualitatively describe the areal extent of volatile<br />

contamination. They are also used to determine the locations of subsequent soil borings and monitoring<br />

wells. For overall characterization of the site, soil gas results are secondary to the soil and groundwater<br />

results. In addition, soil gas results cannot be used to describe the extent of semivolatile or heavy metals<br />

contamination.<br />
