A M B R I A SAMPLING ACTIVITIES AND SAMPLE ANALYSES UST Removal- Two 15,000-gallon fiberglass gasoline USTs were removed on November 5, 2004 by Paradiso Mechanical, Inc of San Leandro, California Mr Mike Infurna and Mr John Jackson of SJCEHD and Cambria field staff were present to witness the removal and condition of the tanks Both tanks were in good condition, with no signs of failure UST Soil Sampling With guidance from Mr Infurna, Cambria staff collected three soil samples beneath each of the USTs and two water samples from the UST pit Six soil samples (TIN, TIM, TIS, T2N, T2M, T2S) were collected from the fuel UST excavation at depths of 17 to 18 fbg in native soil, and two water samples (TP-1-AQ and TP-2-AQ) were collected from the tank pit Soil samples were collected from the tank pit using an excavator The soil was removed from the excavator bucket, packed into clean brass sample tubes, and the tube ends were covered with Teflon tape and plastic end caps Grab water samples were collected using a bailer Sampling locations are shown on Figure 2 Dispenser and Product Piping Soil Sampling: The product dispensers and the associated product piping were removed prior to Cambria's arrival onsite Four soil samples (D-1 through 134) were collected beneath the dispensers and eight soil samples (P-1 through P-8) were collected beneath the piping at approximate depths ranging from 2 5 to 5 5 fbg (Figure 2) Soil samples were collected from native soil in the same manner described above using a backhoe Waste Oil Tank Removal: One 550-gallon waste oil tank and two hoists were removed on November 5, 2004 by Paradiso Mechanical, Inc of San Leandro, California SJCEHD staff and Cambria field staff were present to witness the removal and condition of the tank The tank was in good condition, with no signs of failure Waste Oil Tank Soil Sampling: Cambria staff collected one soil sample (T-3)beneath the waste oil tank at 10 fbg and one soil sample beneath each hoist at 8 fbg (H-1 and H-2) The soil samples were collected using an excavator Soil Chemical Analyses All soil samples were labeled, placed into a cooler with ice, entered onto a chain of custody record, and transported to a California-certified analytical laboratory Soil samples collected beneath the fuel USTs, dispensers and associated piping were analyzed for total petroleum hydrocarbons as gasoline (TPHg), benzene, toluene, ethylbenzene, xylenes (BTEX), and fuel oxygenates (methyl tertiary butyl ether [MTBE], di-isopropyl ether, ethyl tertiary butyl ether, tertiary butyl alcohol [TBA], and tertiary amyl methyl ether) by EPA Method 8260B The soil samples collected beneath the hoists were analyzed for total petroleum 0783 2
