REPORT PREPARATION <br /> E:pon completion of field work and receipt of final laboratory analysis. a report will be prepared <br /> presentin��� the findin�as of the investigation. The report will include a description of' the work <br /> performed and results 01-the sampling and analysis. ConCluSlons, applicable recommendations. maps <br /> and cross-sections will be inCludcd in the report. The report %will he in a format acceptable to the <br /> PIIS-EIII) and the CVRWQCB. and will be rcvie,,�ed and signed by a Calilornia Reuistered <br /> (Jeolo,2ist. If hvdrocarhon-impacted �IIrotuld water is encountered at the site, a recommendation for <br /> the installation ofground water well will he included in the report. <br /> 4.0. FIELD PROCEDURES <br /> All (field procedures «gill be overseen by an AGE geologist or representative under the supervision <br /> of a California Registered Geologist. ProcedurCs for the advancement of borings, soil samplin-g. <br /> "round water sampling. ecluipnlent decontamination and sample shipment etre outlined belo\%. <br /> 4.1. PRORE BORING ADVANCEMENT <br /> Probe bol-ings will be advanced using a van-117oulitcd Geoprobe 5400 direct-push probih- 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 /> 4.1.1. Sol] Sampling Collection and Analysis <br /> Sol] borings to be sampled at discreet five-foot intervals will be sampled usill-,a 1.25" Geoprobe soil <br /> sampling assembly loaded with tour six-inch brass sleeves. Upon sample retrieval. the ends ofthc <br /> second sleeve will be covcred with Teflon sheets, capped and sealed with tape. <br /> ,appropriately sealed and labeled samples Nkill be placed in a chilled container under ice and <br /> transported under chain-ol-custody procedu1-c to a U1 IS-certified laboratory. Each sample sleeve will <br /> be labeled v ith the boring designation. depth. time. date and sampler's initials. Soils encountered in <br /> the bol-illIrs Will he Visually classified by an AGE geolo<List in accordance with the Unified soil <br /> Classification System WSCS). Additionally. soil samples will be field screened for the presence of <br /> volatile organic compounds usin�� an organic vapor meter (C}VNO[), equipped with photo-ionization <br /> detector (1)I1)). <br /> Idranced euEncirnnn crimI, Inc. <br />
