i <br /> - t <br /> � t <br /> Before sampling, the groundwater will be bailed with a teflon bailer until color, <br /> temperature, conductivity, and pH have stabilized. Groundwater will be analyzed <br /> ' for the following <br /> Analysis . PPA Method <br /> TPH gasoline 5030 <br /> TPH diesel 3510 <br /> I BTEX 602 <br /> I A teflon bailer will be used to acquire groundwater samples. Samples will be <br /> immediately placed in an appropriate set of laboratory provided sample vials. For <br /> 1 volitile organic analyses, 40 milliliter sample vials with a teflon backed silicone <br /> septa in an open top lid will be used. The sample vials will be filled completely, <br /> avoiding all air bubbles and transported at 4°C to a State Certified analytical <br /> laboratory. <br /> In addition to the four-inch monitoring well, two two-inch diameter piezometers <br /> { will be constructed in borings P-1, and P-2. The piezometers will be constructed in <br /> the same method as the monitoring well but will not be developed or sampled. A <br /> survey will be completed of the piezometers and well to obtain relative <br /> Ir <br /> groundwater elevations to confirm the gradient information obtained from the <br /> adjacent Mobil Oil Distribution Center site. <br /> ' <br /> 5.0 Site Safety Plan <br /> Due to the limited exposure possible during drilling activities, site activities will be <br /> j completed using level.0 protection. All site personnel will be expected to wear hard <br /> hats and steel toed boots.during drilling activities. All field work will be done in <br /> accordance with applicable OSHA standards. <br /> 1 <br /> 6.0 Statement of Qualifications <br /> This project will be managed by Michael Velzy under the direct supervision of Dr. <br /> Thomas Bruning, a registered civil engineer in the state of California. Dr. Brunsing i <br /> is also a California Registered Fnvironmentai Assessor. The final report of findings <br /> will be certified by Dr. Bruning. <br /> a <br /> E <br /> a <br /> 4 <br /> BRUNSING ASSOCIATES, INC. ®®®® <br /> 1 <br /> r4 <br /> f ! <br /> '- <br />
