GENESIS ENGINEERING&REDEVELOPMENT <br /> The soil samples will be analyzed for the following constituents: <br /> 1. Volatile Organic Compounds ("VOC"); <br /> 2. Semi-Volatile Organic Compounds ("SVOC"); <br /> 3. Title 22 Metals and Hexavalent Chromium; <br /> 4. Total Petroleum Hydrocarbons as gasoline ("TPHg"); <br /> 5. Total Petroleum Hydrocarbons as diesel ("TPHd"); <br /> 6. Benzene, Toluene, Ethylbenzene, and Xylene (`BTEX"); <br /> 7. Polycyclic Aromatic Hydrocarbons ("PAH"); and <br /> 8. Oil and Grease; and <br /> 9. Alkalinity, Calcium, Chloride,pH, Sodium, Potassium, Sulfate, and Sulfide. <br /> The analytical procedures, sample volumes, sample preservation, and holding times are <br /> presented in the Sampling and Analysis Plan. <br /> Since the soil borings will be advanced into the upper water bearing unit in order to <br /> collect a soil sample in the vadose zone immediately above the shallow water bearing <br /> unit, this opportunity will be used to collect water samples from 3 of the on-Site borings <br /> to supplement the data that will be obtained from the monitoring wells; and from the 4 <br /> off-Site borings to provide data on background concentrations. The selected borings will <br /> be advanced into the shallow water bearing unit and a grab groundwater sample <br /> collected. In addition, soil samples will be collected from the 3 on-Site shallow water <br /> bearing unit and will be sent to a geotechnical laboratory for a sieve analysis. This will <br /> provide the information necessary for selection of the screen slot size for the groundwater <br /> monitoring wells. <br /> The grab groundwater samples will be analyzed for the following constituents: <br /> 1. Volatile Organic Compounds ("VOC'); <br /> 2. Semi-Volatile Organic Compounds("SVOC"); <br /> 3. Total Petroleum Hydrocarbons as gasoline("TPHg"); <br /> 4. Total Petroleum Hydrocarbons as diesel ("TPHd"); <br /> 5. Benzene, Toluene, Ethylbenzene, and Xylene (`BTEX"); <br /> 6. Polycyclic Aromatic Hydrocarbons ("PAH"); <br /> 7. Oil and Grease; <br /> 8. Title 22 Metals and Hexavalent Chromium; and <br /> 9. Alkalinity, Calcium, Chloride,pH, Sodium, Potassium, Sulfate, Sulfide, Total <br /> Dissolved Solids, Total Hardness, and Conductivity. <br /> Site Investigation Work Plan 10 Of 18 <br /> DePaoli Property <br /> November 14,2007 <br />
