PREPARATION OF REPORT OF FINDINGS <br /> Following boring advancement,well installation and each ground water monitoring event, a report <br /> will be prepared presenting the findings. Each report will include a description of work performed, <br /> results of the soil/groundwater sampling and analysis,conclusions and recommendations The report <br /> will be in a format acceptable to CRWQCB guidelines, and will be reviewed and signed by a <br /> California Professional Geologist. <br /> 4.0. PROBE BORING FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of California <br /> Professional Geologist. Procedures for the advancement of seven soil probe borings,soil sampling, <br /> grab ground water 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 1.25-inch probing rods. The Geoprobe advances soil probe borings using a hydraulic <br /> hammer to drive soil sampling tools to specified depths. <br /> 4.2. SOIL SAMPLE COLLECTION AND ANALYSIS <br /> Soil samples will be collected at discreet five-foot intervals,starting at 5 feet bsg, and continuing to <br /> the total soil boring depth. Soil samples will be collected using a 1.25-inch Geoprobe soil sampling <br /> assembly loaded with four six-inch stainless steel sleeves. Upon sample retrieval, the ends of the <br /> 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 CDPH-certified laboratory. Each sample sleeve <br /> will be labeledwith the boring designation,depth,time,date and sampler's initials.Additionally,soil <br /> sample duplicates will be field-screened for the presence of volatile organic compounds using an <br /> organic vapor meter(OVM), equipped with photo-ionization detector(PID). <br /> 4.3. GRAB GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> For the collection of grab ground water samples,the soil probe boring will be advanced to the top <br /> Advanced GeoEnvironmental,Inc. <br />
