i - w 15 May 2014 AGE Project No . 06- 1457 Page 3 of 4 Proposed CPT sounding borings and soil boring locations are shown on Figure 2 . At each of the CPT locations , one location will be a cone penetration testing boring to evaluate lithology and groundwater flow units (permeability) and will be advanced to a total depth of 80 feet bsg ; CPT advancement and testing procedures are outlined in Section 3 . 1 . A subsequent boring , adjacent to sounding borings will be advanced to depths of approximately 75 to 80 feet bsg to collect grab groundwater samples . Selected groundwater samples will be analyzed by a State of California Department of Public Health (CDPH )-certified laboratory for the following constituents : j Total petroleum hydrocarbons quantified as gasoline (TPH-g ) in accordance with EPA Method 8015 Modified ; and • Benzene , toluene , ethylbenzene and total xylenes ( BTEX constituents) and fuel ladditives tertiary butyl alcohol (TBA) , di-isopropyl ether ( DIPE) , methyl-tertiary- butyl ether (MTBE) , ethyl tertiary butyl ether (ETBE) , tertiary amyl methyl ether (TAME) , ethylene dibromide ( EDB) and 1 , 2-dichloroethane ( 1 , 2-DCA) by EPA Method 82608 . ( � Laboratory reports for groundwater analysis , testing methods and laboratory quality assurance/quality control (QA/QC) , and sample chain of custody documentation will be presented in a report with findings and recommendations . 2 . 3 . REPORT PREPARATION Upon completion of field work and receipt of final laboratory analysis , a report will be prepared presenting the findings of the investigation . The report will include a description of the work performed and results of the sampling and analysis . Conclusions , applicable recommendations, maps and cross-sections will be included in the report. The report will be in a format acceptable to the SJCEHD and CVRWQCB , and will be reviewed and signed by a California Professional Geologist. 3 .0 . FIELD PROCEDURES - All field procedures will be overseen by an AGE representative under the supervision of a California Professional Geologist. Procedures for the advancement of the CPT borings , groundwater sampling , equipment decontamination and sample shipment are outlined below . it Advanced GeoGnvironmental Inc.
