One (1) other boring was also attempted near the southern portion of the geophysical anomalies, however, this too was terminated at a shallower than anticipated depth.(approximately 4.0 feet) due to subsurface obstructions (over- sized concrete aggregate). A soil boring location map is included in the appendix of J this report. FIELD INVESTIGATION J Purpose The purpose of this limited investigation is to determine whether the likelihood exists for the presence of a UST (s), as directed by the client defined scope of services. This limited investigation is not intended to satisfy the requirements of a soils and/or groundwater investigation as defined by Federal, State, or local regulatory requirements, which in turn may require an additional soils investigation to determine the extent of contamination, if present. Soil samples were not collected for laboratory analysis, since such services were not included in the scope of this investigation. Methods and Observations J Representatives from NWE inspected the area identified as having the geophysical anomalies previously delineated by NORCAL near the southeast corner of the subject Property. The original anomaly field markings by NORCAL were located J in the field. From these reference points, the center of the area deemed most likely to have a UST was first hand angered to a depth of 10.0 feet (B-1). When a UST was not located from this fust boring location, four (4) additional hand augered borings (B-2 through B-5) were completed within close proximity of B-1 towards the north, northeast, east, and west. Care was taken so as to not allow any orientation combination of a small UST to be missed between the borings. All soil cuttings from these hand augered borings were field screened with a PID; however, none of these borings (B-1 through B-5) were found to have detectable organic vapors emitting from the soil samples collected. In addition, no visible signs of staining, odors, or other signs of contamination were observed. J Two (2) additional hand augered soil borings (B-6 and B-8) were also attempted within close proximity of B-1, however, due to subsurface obstructions (over-sized J concrete aggregate and a cast iron pipe line), both borings were terminated at an approximate depth of 1.5 feet. Soil cuttings from these hand augered borings were field screened with a PID; however, none of these borings (B-6 and B-8) were found to have detectable organic vapors emitting from the soil samples collected. In J addition, no visible signs of staining, odors, or other signs of contamination were observed. One (1) other hand augered boring (B-7) was also attempted near the southern portion of the geophysical anomalies, however, this too was terminated at a shallower than anticipated depth (approximately 4.0 feet) due to subsurface obstructions (over-sized concrete aggregate). No organic vapors were detected in the soil cuttings to an approximate depth of 3.9 feet. At an approximate depth of J J
