The Phase II ESA was conducted to further investigate a recognized environmental condition REC at the site as documented in a Phase I Environmental Site Assessment dated April 2, 2010. Historical records indicate that an automobile service/salvage facility and a steel works facility potentially operated on the parcels for at least 50 years. The records review did not provide documentation related to the operation of the facility and environmental assessment, if any, completed at the site. The City of South Tucson conducted a Phase II ESA to collect soil samples from the areas recommended in the Phase I ESA Report. Site sampling activities were conducted on April 21, 2010. The contractor installed eight borings at the site. Two borings were installed by hand to collect near-surface soil samples and the soil samples collected from these two near-surface borings are referenced as SS-3 and SS-4 in this report. Six borings were installed using an auger drill rig to collect samples between 3 and 4 feet below ground surface bgs. As described in the site-specific Sampling and Analysis Plan SAP, samples from each these locations were supposed to be collected at 4 feet bgs and 8 feet bgs, but due to the presence of caliche, auger refusal was encountered and the borings were terminated at the depths described in this report. The samples collected from these borings are referenced as SS-1-4, SS-2-4, SS-5-4, SS-6-3, SS-7-3, and SS-8-3. These samples were analyzed for volatile organic compounds VOCs, polynuclear aromatic hydrocarbons PAHs, and 8 RCRA metals. These analytes were selected due to the historical use of compounds containing these constituents of concern at automotive salvage yards. The following constituents were present in soil at concentrations above the applicable analytical laboratory method detection limits MDLs in soil samples: � SS-1-4: Benzoapyrene, Benzog,h,iperylene, Fluoranthene, Indeno1,2,3-cdpyrene, and pyrene, and all 8 RCRA metals except cadmium, mercury, and silver � SS-2-4: All 8 RCRA metals except mercury, selenium, and silver � SS-3: All 8 RCRA metals except selenium and silver � SS-4 All 8 RCRA metals except mercury, selenium, and silver � SS-5-4: All 8 RCRA metals except cadmium, selenium, and silver � SS-6-3: All 8 RCRA metals except selenium and silver � SS-7-3: Anthracene, Benzoaanthracene, Benzoapyrene, Benzobfluoranthene, Benzog,h,iperylene, Benzokfluoranthene, Chrysene, Fluoranthene, Indeno1,2,3-cdpyrene, and Phenanthrene, Pyrene, all 8 RCRA metals except cadmium, mercury, selenium, and silver � SS-8-3 All 8 RCRA metals except cadmium, mercury, selenium, and silver Of the constituents listed above, Benzoapyrene was present in SS-1-4 0.15 milligrams per kilogram mg/kg and SS-7-3 0.18 mg/kg at concentrations above the applicable State of Arizona residential Soil Remediation Levels SRLs of 0.069 mg/kg, but below the applicable State of Arizona non-residential SRLs of 0.69 mg/kg. A Supplemental Phase II ESA was conducted to further investigate the vertical and horizontal concentration of semi-volatile organic compounds SVOCS, particularly Benzoapyrene in the vicinity of HS-1. The Supplemental Phase II field investigation was conducted on September 10, 2010 by collecting three near surface samples HS-5, HS-6, and HS-7 and submitting the samples for SVOCs analysis. The following constituents were present in soil at concentrations above the applicable analytical laboratory method detection limits MDLs in soil samples: � HS-5: Bis2-ehtylhexylphthalate � HS-6: Bis2-ehtylhexylphthalate � HS-7: Phenanthrene, Pyrene, Benzoaanthracene, Chrysene, and Fluoranthene All constituents were present in concentrations below the applicable residential SRL. Based on the results of the Supplemental Phase II ESA, the results of the Phase II ESA, and the results and conclusions in the Phase I ESA the vertical and horizontal extent of SVOCs has been delineated in the vicinity of HS-1. Therefore, no additiona
