14 August 2000 <br /> AGE-NC Project No. 98-0492 <br /> Page 6 of 8 <br /> The" laboratoryreport for the ground water analy es, 'testing methods, 'laboratory. quality <br /> assurance/quality control(QA/QC) reports; and sample chain.of custody.-documentation will be' <br /> presented in a report with the findings and recommendations. <br /> 3.4: REPORT PREPARATION <br /> Upon completion of field work and receipt of final la oratory analysis,-a report will be prepared <br /> presenting the-findings of the investigation. The report will include a description of.the work <br /> performed and results of thesampling and analysis. Cone usions,recommendations,maps and cross <br /> sections-will be incliided in the-report. The report will e in a.format acceptable to the PHS-EHD <br /> and the CVRWQCB, and will be reviewed and signed l ya California Registered Geologist. <br /> 4.0. FIELD PROCEDURES = <br /> All field procedures will-be overseen by an ACE representative under the supervision of a-California <br /> Registered Geologist. Procedures for,the advancemen .of borings, soil sampling, ground water <br /> sampling, equipment'decontamination and'sample.shipinent are given below. <br /> 4.1. BORING ADVANCEMENT <br /> Borings will be advanced using a van=mounted Geopro e 5400 direct-push probing unit equipped. <br /> with 1.25-inch probing rods. The Geoprobeadvances soi borings using a hydraulic_ Hammer to drive <br /> soil sampling tools to specified depths: <br /> 4.1.1Soil Sampling Collection and Analysis <br /> Soil borings will be sampled continuouslyusing a 2-inc diameter Geoprobe macro-soil sampling <br /> -assembly and a two-inch diam ter four-foot Teflon SIC C. Upon sample retrieval, the ends of the . <br /> liner will be cut and the open ends of the section of soil desired-for analysis will be covered with <br /> Teflon sheets,capped and sealed with tape. <br /> Appropriately,sealed and -labeled samples.will be, placed-in a chilled container'under ice and <br /> transported;under chain-of-custody to a DHS-certified'la, oratory.Each sample sleeve will be-labeled <br /> with the boring designation, depth,time, date and sampl is initials. Soil-samples encountered in the <br /> borings .will be visually classified by'an AGE geolo ist in accordance with the Unified Soil <br /> Classification System(USCS). Additionally; soil sample will be field-screened for the presence of <br /> Advanced GeoEnvirortmental,Inc. <br />
