_ l <br /> Dividend Development Company July 22, 1991 <br /> Report of Findings - North Parcel Page 5 p <br /> SCOPE OF WORK: <br /> Visual site inspections were conducted by TTI personnel on May 14 <br /> and May 22 , 1991. Areas where possible soil staining indicative of <br /> solvent or fuel spillage were inspected. The property around the <br /> barn, storage shed, house, and basement areas on Grant Line Road <br /> were inspected, as well as the property boundary adjacent' to the <br /> Southern Pacific Right of Way. Finally, the property boundary <br /> along the Highway 205 , Right of Way was inspected. No visual <br /> evidence of hazardous materials storage or spillage was observed. <br /> seven (7) groundwater monitoring wells were drilled. for this <br /> project. Soil samples were collected for laboratory analyses at <br /> five foot (51 ) intervals in each well. The' soil samples were <br /> i <br /> collected, sealed, chilled, and transported to a California <br /> certified toxics laboratory. Analyses were performed for petroleum <br /> hydrocarbons using EPA Test Methods 8015M and 8020. Groundwater <br /> was sampled in each we" i after development and purging <br /> approximately four (4) volumes of groundwater from each well. <br /> Water samples were also collected from each well, sealed, chilled, <br /> and transported to a certified toxics laboratory and analyzed for j <br /> i <br /> petroleum hydrocarbons using EPA Test Methods 8015M and 8020. <br /> Analysis for fumigant vapors was performed at each well head five <br /> • (5) days after the monitoring wells were sealed and locked. Vapors <br /> were collected immediately after opening the well heads. The wells <br /> were tested by insertion of a photo ionization organic vapor <br /> analyzer approximately ten inches (1011) into the well. Immediate <br /> and sustained vapor levels were investigated in each well. <br /> Toxic Technology. Inc. <br />
