04 February 2000 <br /> AGE-NC Project No. 95 -0167 <br /> Page 4 of 8 <br /> for the analytes noted in. Section 3 .2 . <br /> Laboratory reports for ground water analyses, testing methods, laboratory quality assurance/quality <br /> control (QA/QC) reports, and sample chain of custody documentation will be presented in a report <br /> with findings and recommendations. <br /> 3 .4. REPORT PREPARATION <br /> Upon completion of field work and receipt of final laboratory 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 the sampling and analysis. Conclusions, applicable recommendations, maps <br /> and cross-sections will be included in the report. The report will be in a format acceptable to the <br /> PHS-EHD and the CVRWQCB, and will be reviewed and signed by a California Registered <br /> Geologist. <br /> 4.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist. Procedures for the advancement of borings, soil sampling, ground water <br /> sampling, monitoring well completion, equipment decontamination and sample shipment are <br /> outlined below. <br /> 4. 1 : PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit <br /> equipped with 1 .25-inch probing rods. The Geoprobe advances soil probe borings using a hydraulic <br /> hammer to drive soil sampling tools to specified depths. <br /> 4. 1 . 1 . Soil Sampling Collection and Analysis <br /> Soil borings to be sampled at discreet five-foot intervals will be sampled using a 1 . 125" Geoprobe <br /> l soil sampling assembly loaded with four six-inch brass sleeves. Upon sample retrieval, the ends of <br /> the second sleeve will be covered with 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 procedure to a DHS-certified laboratory. Each sample sleeve will <br /> be labeled with the boring designation, depth, time, date and sampler's initials. Soils encountered in <br /> the borings will be visually classified by an AGE geologist in accordance with the Unified soil <br /> f <br />
