<br />At each sample location an additional sample of soil was collected and stored in a zip-lock bag
<br />for field analysis of contamination using a photoionization detector (PID). The PID did not
<br />report any indication of contaminated soil at any of the sampled locations. The soil sample
<br />locations are shown on Figure 2. Field notes are included in Attachment A.
<br />ANALYTICAL RESULTS
<br />1 All of the soil samples collected were sent to Argon and were analyzed for various constituents
<br />depending on the contents of the associated USTs. The following samples were analyzed by
<br />' Argon for the following constituents:
<br />• Soil samples collected beneath Tanks #1, 2, 3 and 4 were analyzed for total petroleum
<br />' hydrocarbons as diesel (TPHd) by EPA Method 8015M and benzene, toluene,
<br />ethylbenzene and xylenes (BTEX) by EPA Method 8021B.
<br />• Samples collected beneath Tank #5: total petroleum hydrocarbons as gasoline (TPHg) by
<br />' EPA Method 8015M, BTEX and gasoline oxygenates and additives (tert-butyl alcohol
<br />[TBA], methyl tert-butyl ether [MTBE], di-isopropyl ether [DIPE], ethyl tert-butyl ether
<br />' [ETBE], tert-amyl methyl ether [TAME], 1,2-dichloroethane [DCA] and ethylene
<br />dibromide [EDB]) by EPA Method 8260B.
<br />• Samples collected beneath Tank 46: total extractable petroleum hydrocarbons (TEPH) by
<br />' EPA Method 8015M and BTEX.
<br />• Samples collected beneath Tank #7: TEPH and BTEX by the appropriate EPA Methods.
<br />• Samples collected beneath Tank #8: TPHg, TPHd, TEPH, BTEX, volatile organic
<br />t compounds (VOCs) by EPA Method 8260B, LUFT-5 Metals (cadmium, chromium, lead,
<br />nickel and zinc) by EPA Method 6020, chromium-6 (Cr VI) by EPA Method 7199 and
<br />polychlorinated biphenyls (PCBs) by EPA Method 8082.
<br />t e Samples collected beneath the former dispenser and product lines: TPHg, TPHd, BTEX
<br />and gasoline oxygenates and additives by the appropriate EPA Methods.
<br />• Samples collected beneath the motor oil product lines: TPHg, TPHd, TEPH, BTEX,
<br />' VOCs, LUFT-5 metals, Cr VI and PCBs by the appropriate EPA Methods.
<br />• Samples collected from the stockpiled soil: TPHg, TPHd, TEPH, BTEX VOCs, LUFT-5
<br />Metals, Cr VI and PCBs by the appropriate EPA Methods.
<br />No analyzed constituents were detected in any of the soil samples collected from beneath Tanks
<br />41, 2, 3, 4, 5, 6, 7 and 8. In addition, no analytes were detected in the soil samples collected
<br />' beneath the dispenser and associated product lines.
<br />Total petroleum hydrocarbons as motor oil (TPHmo) was detected in the motor oil product line
<br />' sample PL-2 at a concentration of 62 parts per million (ppm), in motor oil product line sample
<br />PL-6 at a concentration of 29 ppm and in a single composited stockpiled soil sample SP(1,2,3,4)
<br />' at a concentration of 54 ppm. Low levels of chromium, lead, nickel and zinc were detected in all
<br />samples analyzed for LUFT-5 Metals; however, the concentrations of the detected metals appear
<br />to be at background levels. No other analyzed constituents were detected in any soil samples
<br />collected. Table 1 summarizes the laboratory analytical results of the soil samples collected
<br />during the investigation and includes the depth at which each sample was collected. The
