SECTION 4 FIELD ACTIVITIES AND RESULTS <br /> is shown on Figure 4. Figure 5 is a cross-section location Cross-sectional plume maps for <br /> 1,2-DCA are shown on Figures 6 through 8. <br /> Downgradient(Borings CPT-18 to-21,MW-DIS-11,-11D,-12,and-13) <br /> 1,2-DCA (180 gg/L),TPH as gasoline (69 µg/L) and benzene(0.53µg/L)were present in <br /> monitoring well MW-DIS-11. A low concentration (2.6µg/L) of 1,2-DCA waspresent in <br /> boring CPT-20 (87). MW-DIS-12 was installed at the same location as CPT-20 to monitor <br /> groundwater at the leading edge of the plume. MW-DIS-12 was non-detect for all <br /> compounds. MW-DIS-11D contained MTBE at a concentration of 0.52 pg/L. <br /> Cross-gradient (CPT-16,-17,-22,-23,and-24,MW-DIS-14 and-14D) <br /> Detectable levels of 1,2-DCA were present in borings CPT-16 (109'),CPT-22(84'),CPT-23 <br /> (107' and 144') and monitoring well MW-DIS-14. <br /> I <br /> i <br /> f <br /> I <br /> i <br /> t <br /> I <br /> SFOICPTMW_REPORT KS-DOCIOM70036 4.3 <br /> I <br />
