J 14 October 2014 <br /> AGE Project No. 11 - 1847 <br /> Page 4 of 6 <br /> 2 . 5 . PREPARATION OF REPORT OF FINDINGS <br /> A report documenting the findings of the soil borings , well installations , development <br /> and survey will be prepared following performance of field work and receipt of all <br /> applicable data . Additionally , quarterly reports will be prepared following each <br /> groundwater monitoring event. Each report will include a description of work performed <br /> and the results of the groundwater sampling and analysis . Conclusions and <br /> recommendations will also be included , if applicable for each report. All reports will be in <br /> a format acceptable to the EHD and 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 under the supervision of <br /> a California Professional Geologist. Procedures for boring advancement , soil sample <br /> collection , well installation , well development and well sampling are described below. <br /> 3 . 1 . BORING ADVANCEMENT AND SOIL SAMPLING <br /> Utilizing a truck-mounted , hollow-stem auger drill rig equipped with 8 . 25-inch diameter <br /> hollow-stem augers , four soil borings will be advanced to depths of approximately 90 <br /> feet bsg for the purpose of logging lithology and collection of soil samples . Thereafter, a <br /> second pilot soil boring will be advanced to a depth of approximately 40 feet bsg for the <br /> purpose of installing a shallow groundwater monitoring well . <br /> Beginning at a depth of 10 feet bsg , relatively undisturbed soil samples will be collected <br /> from all soil boring locations at 5-foot intervals using a California modified split-spoon <br /> sampler fitted with 2-inch diameter, 6-inch long steel sleeves . Upon removal from the <br /> sampler, the sample sleeves will be separated . The exposed ends of a selected sleeve <br /> will be covered with Teflon sheets , capped , and sealed with tape . Soils sampled in the <br /> borings will be visually classified by an AGE geologist in accordance with the Unified <br /> Soil Classification System ( USCS) . Additionally, soil samples will be field screened for <br /> the presence of volatile organic compounds using an organic vapor meter (OVM) , <br /> equipped with a photo-ionization detector (PID) . Soil sample descriptions and OVM <br /> readings will be recorded on a log for each boring . <br /> Following sample collection , each preserved sample sleeve will be labeled with the <br /> boring location , depth , time , date , and sampler's initials . Appropriately sealed and <br /> labeled samples will be placed in a chilled container and transported under chain of <br /> custody to a CDPH -certified laboratory for analysis for the constituents listed in Section <br /> 2 . 2 . <br /> Advanced GeoGnvironmental Inc. <br />
