903806-SS4 CON-53 <br /> 4.6.5 Table 4.6-1 provides the estimated contaminant quantities present in <br /> soil and groundwater. <br /> 4.6.6 Neither TCE nor PCE was detected in soil samples from Contaminant <br /> Areas 4, 5, and 6. The soil gas samples, with a far lower detection limit, <br /> showed that these solvents are generally present in these areas. The <br /> concentrations found in the soil gas, however, were generally well below <br /> those found in Contaminant Areas 1, 2, and 3. This 'suggests that the <br /> quantities present in soils in Contaminant Areas 4,- 5, and-6 would not <br /> significantly affect the total quantities present on the site. <br /> 4.6.7 The calculations are shown in Appendix Q. <br /> Q <br /> �L. <br /> :n. <br /> 4-197 <br />
