A Chain of Custody will be <br /> completed for all samples collected and tracked to ensure sample integrity. <br /> DetectionLimits: F133E I-PH-0 Ethers TBA <br /> s <br /> 3.2 Groundwater Analyses <br /> One groundwater hydropunch sample from.SIB-1 will be submitted to Sherwood Laboratories <br /> of Hilmar(State Certifed Laboratory#1.400) for the following analysis: <br /> • benzene,tolueoe,etbylbenzene and xylene(BTEX)by EPA method 602 <br /> • gasoline range petroleum hydrocarbons(TPH-G)by EP.A,method 8015(m) <br /> • MTBE,ETRE,TAME,DIPE&TBA by EPA method 8260. <br /> The detection limits for these compounds we listed below. A Chain of Custody will be <br /> completed for all samples collected and tt-acked to ensure sample integrity. <br /> Detection Linuts KFEX 7?H-0ers <br /> Ater µ <br /> 4.0 SCHEDULE&REPORTING <br /> Geological Technics Inc. anticipates beginning fieldwork no later than 30 days after work <br /> plait approval and upon issuance of the dr7ilijpermit. The infortnatior►gathered during this <br /> phase of work will be presented in a reportthat will include a summary of the geology as <br /> well as the results of sample analyses. Dr. Ray Kablanow, a registered professional <br /> geologist, will supervise the project. Copies of the report will be forwarded to both the <br /> appropriate County and State regulatory agencies(SJC PUS1EHD and CRWQCB)_ <br />
