I <br /> 22 May 2013 <br /> AGE Project No . 11 - 1847 <br /> Page 4 of 6 <br /> findings. All reports will include descriptions of work performed and results of sampling and <br /> analysis. Also , conclusions and applicable recommendations will be included in the reports . <br /> Reports will be in a format acceptable to the CVRWQCB , and will be reviewed and signed <br /> by a California Professional Geologist. <br /> 3.0 . FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative working under the <br /> supervision of a California Professional Geologist. Procedures for advancing the soil <br /> boring , collection and analysis of soil and groundwater samples, monitoring well <br /> completion , equipment decontamination and sample handling are presented below. <br /> 3. 1 . PROBE SOIL BORING ADVANCEMENT <br /> Utilizing a truck-mounted , hollow-stem drill rig equipped with 8 . 25-inch diameter hollow- <br /> stem augers, one pilot soil boring ( B5) will be advanced to depths of approximately 100 <br /> feet bsg . <br /> 3 . 1 . 1 . Soil Sampling <br /> Beginning at 60 feet bsg , relatively undisturbed soil samples will be collected from the soil <br /> boring location at 5-foot intervals using a California modified split-spoon samplerfitted with <br /> 2-inch diameter, 6-inch long brass sleeves . Upon removal from the sampler, the sample <br /> sleeves will be separated with a knife . The exposed ends of the second sleeve will be <br /> covered with Teflon sheets , capped , and sealed with tape . Soils sampled in the borings will <br /> be visually classified by an AGE geologist in accordance with the Unified Soil Classification <br /> System ( USCS) . Additionally, soil samples will be field screened for the presence of volatile <br /> organic compounds using an organic vapor meter (OVM ) , equipped with a photo-ionization <br /> detector (PID). Soil sample descriptions and OVM readings will be recorded on a log for <br /> each boring . <br /> Following sample collection , each preserved sample sleeve will be labeled with the boring <br /> location , depth , time, date, and sampler's initials . Appropriately sealed and labeled <br /> samples will be placed in a chilled container and transported under chain of custody to a <br /> CDPH-certified laboratory for analysis for the constituents listed in Section 2 .3 . <br /> J <br /> Advanced GeoEnvironmental, Inc. <br />
