Ground water sample collectioh,pro_cedur,s are described in.Section 4.S <br /> 3.5. REPORT PREPARATION <br /> Upon completion of fieldwork and_xeceipt of final laboratory analysis, a:report;-will be prepared <br /> _ presenting the findings of the investigation. 'The report=will include, 'a.-aescriptiori,of the,work x <br /> - . performed and results of the sampling and analysis. Conclusions and applicable recommendations <br /> will be included in the report. The report will'be-in-a'format acceptable to,the PHS-EHD and the <br /> CVRWQCB, and.will be feviewed 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 /> r Registered Geologist. Procedures for the'advancement ofdborings, soil sdini lin&ground water- <br /> _ sampling,equipment.decontarriination and sample:shipment are outlined-below: <br /> 4.1. - BORING.ADVANCEMENT AND SOIL SAMPL-IN.G - <br /> ., <br /> Soil borings will be -advanced using'hollow-stem-auger drilling techniques: Soil samples N�11h e <br /> z <br /> _ collected from each soil boring at five-_foot intervals.-Relatively undisturbed soil samples will be ; <br /> collected in each of the borings using a Califoi-nia-modified:split-spoon sampler fitted with 2-inch ' <br /> diameter, 6-inch long brass sleeves:Upon removal.from4he sampler, the,-sample sleeves will be <br /> separated with a cleari soil knife: The.exposed ends of the second sleeve:will be covered with Teflon <br /> sheets, capped and sealed with tape..Soils sampledin.the.borings will be visually classified by an , <br /> AGE geologist in accordance.'with the Unified Soil Classificafion System(USCS). Additionally, soil . <br /> T samples will be field sci-eened.f6r the presence of volatile organic compounds using an.organic.vapor <br />.. _ meter(OVM). Sol] sample descriptions and OVM readings will be'recorded.on a log-for each boring. <br /> If the lateral extent of the impacted soil surrounding the former USTs is not defined by-the limited l , <br /> number of sail boring'proposed in this particular.scope of work,than additioi?al soil borings rriay be. ., <br /> advanced simultaneous-with this mobilization;with prior.approval.from the responsible party.and' •` .I <br /> the PHS-EHD to verify location and depth. :• °", "t <br /> y <br /> Following sample collection,.ea_ch preserved sample•sleeve.wilI be labeled:wi'th the boring location, <br /> ' wil e laced in <br /> . depth,time, date and sampler s�rutials:.=Appropriately sealed and.labeled samples _1.b p - , <br /> J, <br /> ".
