REPORT PREPARATION <br />Upon completion of field work and receipt of final laboratory analysis, a report will be <br />prepared presenting the findings of the investigation. The report will include a <br />description of the work performed and results of the sampling and analysis. <br />Conclusions, applicable recommendations, maps and cross-sections will be included in <br />the report. The report will be in a format acceptable to CVRWQCB, and will be reviewed <br />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 the advancement of the soil borings, <br />groundwater sampling, equipment decontamination and sample shipment are outlined <br />below. <br />3.1. SOIL BORING ADVACMENT AND SOIL SAMPLE COLLECTION <br />Utilizing a van-mounted direct push drilling rig equipped with 1.5-inch diameter hollow- <br />probing rods, a total of seven (7) soil borings will be advanced to a depth of 10 feet bsg. <br />Proposed boring locations are illustrated on Figure 2. <br />3.2. SOIL SAMPLING <br />Soil samples will be collected from selected borings at discrete five-foot intervals <br />beginning at five feet bsg using a 1.25 inch Geoprobe soil sampling assembly loaded <br />with a two-foot acetate liner. Upon sample retrieval, a selected portion of the liner will be <br />cut and covered with Teflon sheets, capped, and sealed with tape. <br />Sealed and labeled samples will be placed in a chilled container under ice and <br />transported under chain-of-custody procedure to a CDPH-certified laboratory. Samples <br />will be analyzed for the constituents listed in Section 2.2. Each sample will be labeled <br />with boring designation, depth, time, date and sampler's initials. Soils encountered in <br />the borings will be visually classified by AGE personnel 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 a photo-ionization detector (PID) <br />calibrated to isobutylene. <br />3.3. EQUIPMENT DECONTAMINATION <br />Prior to use, all sampling tools used for sample collection will be thoroughly rinsed with <br />clean water after being washed with a solution of Alconox. All probe tooling and rods will <br />be cleaned prior to advancement at each probe boring location.
