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 laboratory analysis. Conclusions, applicable recommendations, maps <br />and cross-sections will be included in the report, as will copies of the laboratory reports, testing <br />methods, laboratory quality assurance/quality control (QA/QC) reports, and sample chain of custody <br />documentation. The report will be in a format acceptable to the PHS-EHD and the CVRWQCB, and <br />will be reviewed and signed by a California Registered 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, equipment decontamination and sample shipment are 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 1.125 -inch probing rods. The Geoprobe advances soil probe borings using hydraulic <br />pressure and a pneumatic hammer to drive soil sampling tools to specified depths. <br />4.2. SOIL SAMPLE COLLECTION AND ANALYSIS <br />Soil borings will be sampled at discreet five-foot intervals using a 1.25" Geoprobe soil sampling <br />assembly loaded with four six-inch brass sleeves. Upon sample retrieval, the ends of the second <br />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-custodyto a DHS -certified laboratory. Each sample sleeve will be labeled <br />with the boring designation, depth, time, date and sampler's initials. Soils encountered in the borings <br />will be visually classified by an AGE geologist in accordance with the Unified Soil Classification <br />System (USCS). <br />Advanced GeoEnvironmental, Inc. <br />
