i CIV. SITE RECONNAISSANCE AND INTERVIEWS The following site specific information was obtained from direct observations and an interview with �Z Mr. Gum Arora on February 24, 2005. This was the date of the fatal inspection of the property. There is one domestic well and one septic system with a septic tank on the property that serve the single family residential structure. The entire acreage was walked and surveyed for evidence which may suggest surface and/or subsurface contamination: No hazardous materials were noted on the property, other than de minimus materials. This included 25-gallon barrels that are used to store aluminum cans. No evidence of drug manufacturing or the dumping of drug-related chemicals was observed on the Frontage Road, or in the rear of the property. There were no tire tracks leading to the back of the property which would indicate dumping. Containers, other than the referenced barrels, were not observed. No evidence of solid waste disposal was noted, except for a mound of large chunks of concrete northeast of the residence. This may be remnants of the above-referenced building observed in the 1937 and 1952 aerial photographs. Other non-hazardous solids wastes noted were twine,plastic, wood, metal, concrete, and baling wire. Old farm tractors and implements are located near the residence. The site was carefully inspected for environmental concerns originating from discolored, disturbed/subsided soils, stressed vegetation or unusual/noxious odors. None of these environmental indicators were observed. As evidenced by the attached photographs, no hazardous materials are stored on-site and there was no indication or observations of spills or other items associated with hazardous materials. An important concern associated with the environmental assessment of open properties is the issue of buried pesticide containers or discarded items. It was an occasional practice to dispose of containers or discarded items by this method many years ago. To detect these types of underground artifacts is difficult even with the use of ground penetrating radar or other types of non-intrusive, subsurface analyses. The land surface did not exhibit visual indicators for buried containers such as surfacing of product residue, soil mounding, or localized soil depressions. Given the extreme compactness of the underlying soils, in particular the hardpan stratum that exists in this locale, buried material may be considered highly unlikely. It is usually after a contaminant plume has impacted a domestic well that buried pesticide containers are discovered. If buried items are discovered at any time in the future, particularly during the emplacement of underground utilities,the San Joaquin County Environmental Health Department must be contacted immediately. An electrical transformer exists on the subject property adjacent to the north side of the existing residential structure. This transformer appears to be relatively new. It is unknown if this transformer contains polychloride biphenyls (PCBs). Although no indication was noted of external oil leakage, if there was a leak or explosion, it would be the responsibility of the transformer owner to mitigate environmental contamination. 4 Chesney Consulting
