The groundwater samples <br /> were analyzed for TPHG by EPA Method 8015 modified with purge and <br /> trap preparation 5030 (GC/FID) with detection limits noted in the <br /> Laboratory Data Sheets. EPA Method 602 will be utilized for BTEX <br /> with a detection limit of 0 . 5ug/1 as required by the SJCEHD. <br /> The analysis for the five samples are depicted in Table 1, with <br /> the results in Parts Per Million (PPM) . T-BUT is used to <br /> identify Tertiary Butanol an alcohol used in some oxygenated <br /> gasolines. Copies of the COC documentation and Laboratory Data <br /> Sheets, with analytical detection limits, are contained in <br /> Appendix B. <br /> Copies of the Analytical Results were sent directly to the SJCEHD <br /> and CVRWQCB by the laboratory. <br /> TABLE 1 Concentrations in PPx b <br /> .
