07 November 2012 <br /> AGE Project No. 11-2216 <br /> Page 2 of 3 <br /> encountered at the site around 10 feet bsg. Approximate boring locations are illustrated in <br /> Figure 2. <br /> Borings will be advanced using a GeoProbe® or PowerProbe® direct-push drill rig. Grab <br /> groundwater samples will be collected from three borings; soil samples will be collected <br /> from two of the borings. <br /> Upon completion of the field work and receipt of laboratory analysis, a brief report will be <br /> prepared. The report will be reviewed and signed by a California Professional Geologist. <br /> PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using a van-mounted direct-push probing unit equipped <br /> with 1.25-inch probing rods. The probe unit advances soil borings using a hydraulic <br /> hammer to drive soil and groundwater sampling tools to specified depths. <br /> SOIL SAMPLE COLLECTION AND ANALYSIS <br /> Soil samples may will be collected at discreet five-foot intervals using a 1.25-inch <br /> Geoprobe®soil sampling assembly loaded with four six-inch stainless steel sleeves. Upon <br /> sample retrieval, the ends of the second sleeve will be covered with Teflon® sheets, <br /> capped and sealed with tape. <br /> Appropriately sealed and labeled samples will be placed in a chilled container under ice <br /> and transported under chain-of-custody procedure to a California Department of Public <br /> Health (CDPH)-Certified laboratory. Selected soil samples (two expected)will be analyzed <br /> fo r: <br /> • Organochlorine Pesticides in accordance with EPA Method 8080. <br /> GRAB GROUNDWATER SAMPLE COLLECTION AND ANALYSIS <br /> Grab groundwater samples will be collected using a Geoprobe® push-driven water <br /> sampling device. The water sampling device will be advanced approximately four feet into <br /> the water-bearing zone. Grab groundwater samples will be collected using a Geoprobe® <br /> water sampling assembly fitted with fitted with a new PVC one-half inch diameter <br /> 0.010-inch slotted temporary well screen. The groundwater sample will be extracted using <br /> inertial action by lowering Teflon® tubing through the hollow center of the push rods into <br /> Advanced GeoEn ironmental,Inc. <br />
