<br /> removed from its liner to be used as an aide to the on-site professional in
<br /> ' logging the material at that depth.
<br /> Soil samples collected for analysis were analyzed using EPA Method 5030/LUFT
<br /> ' for total petroleum hydrocarbons (TPH) as gasoline, EPA Method 3550/LUFT for
<br /> kerosene, diesel, and motor oil, EPA Method 8260B for benzene, toluene, ethyl-
<br /> benzene, total zylenes (BTEX), oxygenates, ethylene dibromide, and 1,2-
<br /> dichloroethane, EPA Method 6010B for priority pollutant heavy metals, EPA
<br /> Method 8010 for purgeable halocarbons, and EPA Method 8021B for aromatic
<br /> ' halocarbons. Analyses were conducted by GeoAnalytical Laboratories, Inc., a
<br /> State-certified laboratory in Modesto, California.
<br /> 3.3 Groundwater Sampling
<br /> ' All sampling equipment was cleaned prior to commencement of sampling. A
<br /> travel blank provided by the laboratory accompanied the sample vials from the
<br /> time they were picked up from the lab to the time they were delivered to the
<br /> ' lab.
<br /> Care was taken to ensure that no air space existed in the vials by inverting each
<br /> vial to check for bubbles, if bubbles were present, the groundwater was re-
<br /> sampled. The samples were analyzed within 14 days according to their EPA
<br /> ' methods. The water sample collected for analysis was analyzed using EPA
<br /> Method 5030/LUFT for total petroleum hydrocarbons (TPH) as gasoline, EPA
<br /> Method 3510/LUFT for kerosene, diesel, and motor oil, EPA Method 8260B
<br /> ' for benzene, toluene, ethyl-benzene, total zylenes (BTEX), oxygenates, ethylene
<br /> dibromide, and 1,2-dichloroethane, EPA Method 6010B for priority pollutant
<br /> heavy metals, EPA Method 8010B for purgeable halocarbons, and EPA Method
<br /> 8020 for aromatic halocarbons. Analyses were conducted by the State-certified
<br /> laboratory GeoAnalytical Laboratories, Inc., in Modesto, California.
<br /> ' 4.0 Analytical Results
<br /> ' 4.1 Soil Analytical Results
<br /> ' The soil sample analysis of Boring B-1 indicated that the out of the analytes tested,
<br /> only the heavy metal were present at or above the laboratory reporting limits. All
<br /> • other analytes were ND, none detected. The only soil sample that was analyzed
<br /> ' for metals was sample B-1 at 10.0'. The only metals present in that soil sample
<br /> were arsenic, barium, chromium, cobalt, copper, lead, nickel, vanadium, and zinc.
