OUARTERLY GROUND WATER MONITORING REPORT <br /> 5491 F Street,Banta,California <br /> 2.2 Groundwater Analysis <br /> Groundwater samples were collected by Aegis from six on site groundwater monitoring <br /> wells on 1 February 1991. Groundwater samples were collected according to Aegis' SOP. <br /> The samples were submitted to Coast-to-Coast Analytical Services of San Luis Obispo for <br /> a fuel fingerprint analysis. The samples were analyzed for concentrations of total <br /> purgeable petroleum hydrocarbons (TPPH as gasoline, diesel 2, crude oil, jet fuel, <br /> kerosene and stoddard), benzene, toluene, ethyl benzene, and xylenes (BTEX), 1,2- <br /> dichloroethane (EDC) and ethylene dibromide (EDB). The samples were extracted by <br /> EPA method 5030 (purge-and-trap) and analyzed by a gas chromatograph/mass <br /> spectrometer (GC/MS), EPA method 8240. Table 2 summarizes the groundwater <br /> analytical results performed to date. Copies of the certified analytical results and chain-of- <br /> custody records of samples collected by Aegis are included in Appendix B. <br /> 90-099A.RPT -6- <br />
