1 <br /> ' Additional Soil and Ground Water Assessment Report <br /> VAN BUSKIRK GOLF COURSE FACILITY <br /> 1740 Houston Avenue, Stockton, California <br /> APPENDIX A <br /> ' FIELD PROCEDURES AND PROTOCOLS <br /> All field procedures were overseen by an AGE representative. Procedures for soil and ground water <br /> ' sampling,well installation and development, equipment decontamination,boring abandonment, and <br /> sample shipment are outlined below. <br /> ' A.1. SOIL SAMPLING PROCEDURES <br /> ' Soil borings were advanced by Cental Valley Drilling using hollow-stem auger drilling techniques. <br /> Soil borings were sampled on a continuous basis and/or collected at five-foot intervals. Relatively <br /> undisturbed soil samples were collected in each of the borings using a California-modified split- <br /> spoon sampler fitted with 2-inch diameter, 6-inch long brass sleeves. Upon removal from the <br /> sampler, the sample sleeves were separated with a clean soil knife. The exposed ends of the first <br />! ' sleeve were covered with Teflon sheets, capped and sealed with tape. Soils encountered in the <br /> borings were visually logged by an AGE geologist in accordance with the Unified Soil Classification <br /> System (USCS). <br /> • Following sample collection, each preserved sample sleeve was labeled with the borin location, <br /> depth,time, date and sampler's initials. Appropriately sealed and labeled samples were plin an <br /> ' ice-chilled container and transported under chain-of-custody procedure to McCampbell Ailalytical, <br /> Inc., a DHS-certified laboratory. <br /> Soil cuttings generated during drilling of the soil borings were contained in DOT-approved 55-gallon <br /> drums which were appropriately labeled for storage. Drums containing soil and decontamination <br /> water are stored on-site pending appropriate removal and disposal. <br /> ' A.2. GRAB GROUND WATER SAMPLING PROCEDURES <br /> Grab ground water samples were collected from the first water-bearing unit encountered in soil <br /> ' borings B-1 through B-3. A grab ground water sample was collected from soil boring B-1 by <br /> lowering a disposable polyethylene bailer inside the hollow-stem augers and retrieving the bailer to <br /> ground surface. Grab ground water samples were collected from soil borings B-2 and B-3 using <br /> hydropunch-equivalent water sampling techniques. The water sampling device consists of a push- <br /> driven water sampling assembly fitted with a pre-cleaned one-inch diameter 0.010-inch slotted PVC <br /> well screen. Prior to encountering the ground water table, the water sampling device was advanced <br /> four to five feet into the water-bearing zone. Subsequently, the sampling assembly was retracted <br /> �j approximately four feet exposing the well screen to the desired sampling interval. Ground water <br /> samples were extracted by lowering a stainless steel bailer through the hollow center of the push rods <br /> i <br /> Advanced GeoEnvironmental,Inc. <br /> 1 <br />
