BUR <br /> Oxygen readings in soil gas probes ranged from 14.3 percent by volume in SGP-2A to <br /> 20.1 percent by volume in SGP-9A. Carbon dioxide readings ranged from 0.3 percent by volume <br /> in SGP-IOB to 7.3 percent by volume in SGP-2A. These data are generally consistent with <br /> previous soil gas data at this site. The relative pressure of the probes ranged from -0.10 inches of <br /> water to 0.10 inches of water indicating that the pressure within the soil gas probes is near <br /> equilibrium with atmospheric pressure. <br /> Soil gas monitoring will be conducted again during the second quarter of 2002.
