' I 1 February 2003 <br /> • AGE-NC Project No. 98-0520 <br /> ' Page 6 of 7 <br /> 3.3. REPORT PREPARATION <br /> 1 <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,and <br /> maps will be included in the report. The report will be reviewed and signed by a California <br /> ' 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 probe borings,soil sampling,ground <br /> water sampling,equipment decontamination,.sample shipment,and boring abandonment are outlined <br /> below. <br /> 10 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 /> ' or pneumatic hammer to drive soil and ground water sampling tools to specified depths. <br /> ' 4.2. SOIL SAMPLING PROCEDURES <br /> Soil borings will be sampled at discreet five-foot intervals using a 1.125" Geoprobe soil sampling <br /> ' assembly loaded with four six-inch brass sleeves. Upon sample retrieval, the ends of the,second or <br /> other selected 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 <br /> in the borings will be visually classified by an AGE geologist in accordance with the Unified-Soil <br /> Classification System(USCS). Additionally, soil samples will be field-screened for the presence of <br /> ' volatile organic compounds using an organic vapor meter(OVM), equipped with photo-ionization <br /> detector (PID). <br /> 1 Advanced GeoEnviron mental,Inc. <br />
