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 including diagram of septic system, location of sampling points and results of the <br /> sampling and analysis. Conclusions and applicable recommendations will be included in the report. <br /> The report 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 soil borings, soil sampling, equipment <br /> decontamination, sample shipment, and boring abandonment are outlined below. <br /> 4.1. 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.The borings will possibly have to be angled <br /> to reach under the specified sampling locations. <br /> 4.2. SOIL SAMPLING PROCEDURES <br /> Soil borings to be sampled at specified depths using a 1.125 Geoprobe soil sampling assembly <br /> loaded with four six-inch brass sleeves. Upon sample retrieval, the ends of the second sleeve will <br /> 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, time, date and sampler's initials. <br /> 4.3. EQUIPMENT DECONTAMINATION <br /> Prior to use,all sampling tools used for sample collection will be thoroughly rinsed with clean water <br /> after being washed with a solution of Alconox and water. <br /> Advanced GeoEnvironmental,Inc. <br />
