14 September 1998 <br /> AGE-NC Project No. 98-0468 <br /> Page 7 of'10 <br /> . 3.6. 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 the results of the sampling' and analysis. Conclusions and applicable <br /> recommendations 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 /> A.O. 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 soil sampling, in-situ ground water sampling, monitoring <br /> well installation; well development, ground water sampling,e_quipm_ ent decontamination and sample. <br /> shipment are outlined below.,, <br /> 4.1: SOIL SAMPLING PROCEDURES <br /> Soil borings will be advanced using hollow-stem auger,drilling techniques. Soil borings will be <br /> continuously sampled using continuous core sampler and drive samples collected at five-foot <br /> intervals. Relatively undisturbed 'soil samples will be collected in each,of the borings using a <br /> California modified split-spoon'sampler fitted with 2-inch diameter, 6-inch long brass,sleeves.Upon <br /> removal from the sampler, the sample sleeve is separated with a clean soil knife. The exposed ends <br /> of the second sleeve will be covered ,with Teflon sheets, capped and sealed with tape. Soils <br /> encountered in the borings will be-visually classified by an AGE geologist in accordance with the <br /> -Unified soil Classification System(USCS). Additionally, soil samples will be field screened for the <br /> presence of volatile organic compounds using an organic vapor meter(OVM). <br /> Following sample collection, each preserved sample sleeve will be labeled with the boring location, <br /> depth,time,date and sampler's initials. Appropriately sealed and labeled samples will be placed in <br /> a chilled container under ice and transported under chain-of-custody procedure to a DTSC=certified <br /> -laboratory. <br /> 4.2. IN=SITU GROUND WATER SAMPLING PROCEDURES <br /> For the collection of in=situ"grab"`ground water samples, soil borings will be advanced to the top <br /> of the ground viwater'table as identified by collection of a saturated soil sample.
