20 August 2018 AdvancedGeo <br />AGE Project No. 13-2557 Environmental <br />Page 4 of 6 Wag <br />2.6. PREPARATION OF REPORT OF FINDINGS <br />A report documenting the findings of the well installations, development and survey will <br />be prepared following performance of field work and receipt of all applicable data. <br />Additionally, quarterly reports will be prepared following each groundwater monitoring <br />event. Each report will include a description of work performed and the results of the <br />groundwater sampling and analysis. Conclusions and recommendations will also be <br />included, if applicable for each report. All reports will be in a format acceptable to the <br />CVRWQCB, and will be reviewed and signed 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 well installations, soil sample <br />collection, well development, well survey and well sampling are described below. <br />3.1. BORING ADVANCEMENT AND SOIL SAMPLING <br />Six pilot soil borings will be advanced at the site to maximum depths of 20 feet bsg and <br />one pilot soil boring will be advanced at the site to a maximum depth of 40 feet bsg. <br />Borings will be advanced utilizing a truck-mounted hollow-stem drill rig equipped with <br />8.25-inch diameter hollow-stem augers. Relatively undisturbed soil samples will be <br />collected from the soil borings at five-foot intervals beginning at 5 feet bsg using a <br />California modified split-spoon sampler fitted with 2-inch diameter stainless steel sleeves. <br />Upon removal from the sampler, sample sleeves will be separated and the exposed ends <br />of a selected sleeve will be covered with Teflon sheets, capped and sealed with tape. <br />Soil encountered in the borings will be visually classified by an AGE staff member in <br />accordance with the Unified Soil Classification System (USCS). Additionally, soil samples <br />will be field-screened for the presence of volatile organic compounds using an organic <br />vapor meter (OVM) equipped with a photo-ionization detector (PID). Soil sample <br />descriptions and OVM readings will be recorded on a log for each boring. Following <br />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 <br />placed in a chilled container with ice and transported under chain-of-custody procedure <br />to an ELAP-certified laboratory for analysis for the constituents listed in Section 2.3. The <br />proposed well locations are illustrated in Figures 2 through 6. <br />3.2. MONITORING WELL COMPLETION AND ELEVATION SURVEY <br />Soil borings will be single-completed as groundwater monitoring wells utilizing 2-inch <br />diameter schedule 40 polyvinylchloride (PVC) 0.020-inch slotted well screen and blank
