TABLE 4-4 (continued) <br /> RESULTS OF VOLATILE ORGANIC COMPOUNDS ANALYSES IN SOIL <br /> See Figure 2-1 for approximate soil boring locations and Figure 2-2 for approximate monitoring well locations. Information included on this table was <br /> used in generating the isoconcentration maps for this site. <br /> n Volatile organic compounds analyzed by EPA Method 8240, 8010, and 8020. See details below: <br /> * Borings S136, S137, S1314, S1317, MW11A and MW12B were installed by Harding Lawson Associates and analyzed for VOC's by EPA Method <br /> 8240 using gas chromatograph/mass spectroscopy (GC/MS) procedures. <br /> * Borings TYB1 through TYB5, TYB7 through TYB30, #1 through#26, MW1413, and MW15B were installed by IC and analyzed by EPA <br /> Method 8010 using gas chromatograph (GC) procedures. <br /> * Borings TYB7 through TYB34 were installed by IC and analyzed by EPA Method 8020 using GC procedures. <br /> 1,1,-DCA 1,1-Dichloroethane <br /> 1,2-DCE 1,2-Dichloroethene <br /> 1,1,2,2-TCA 1,1,2,2-Trichloroethane <br /> 1,1,1-TCA 1,1,1-Trichloroethane <br /> TCE Trichloroethene <br /> PCE Tetrachloroethene <br /> TCFM Trichlorofluoromethane <br /> < Symbol denotes concentration below method detection limits as noted. <br /> µg/kg Micrograms per kilogram <br /> NA Not analyzed <br /> bgs Below ground surface <br /> /u/csing/tract'/ri/Lab les/ritbl4-4 4-4-8 <br />
