None of the individual <br /> PAH compounds or BaP equlvalents exceeded the Industrlal/Residential SRVs. <br /> Polvchlorinated Bi�„�yls IPCBs,� <br /> PCSs wer-e analyzed In ali the samples collected from the test pits using method 8082A. An <br /> elevated concentration of PCB 1254 was detected in TP-3 (5� at 9.78 mg/kg, whlch is above <br /> the MPCA Restdential and Industrial SRVs of i.2 mg/kg and 8 mg/kg, respectively. The Tler <br /> I SLV of 0.13 mg/kg was also exceeded in test ptt samples TP-3 (6� and TF-3 (5'). No other <br /> PCBs were identified in the soll samples above their respective Industrial/Residentlal SRVs <br /> or Tier I SLVs. <br /> �lesel Range Organ�i ,�(pL� <br /> Low levels of DRO were ldentified fn all four of the test plts at concentrations ranging from <br /> 6.57 mg/kg to 84.9 mg/kg. Ail of the DRO detections were below the MPCA's unregulated <br /> sof! reuse guidance of 100 mg/kg. <br /> Conclusions <br /> Based on the results of the [nvestigation, the surtiaal soil In the area cansists of a sandy <br /> clay fili soils tq depths ranging from 5 to 15 feet. The sandy day soifs are overlaying a <br /> debris layer that extends to approximately 20 feet below ground surtace and possibly <br /> beyond. When compared to residential regulatory Iimits, the analytical results from the four <br /> tfie test pits showed concentrations of arsenic and lead above residential SRVs. However, <br /> arsenic at the Identifled concentratlon can also be naturally occurring in soil. The TCLP lead <br /> concentratfons show a non-hazardous characterlstic. <br /> Screened samples for VOCs did not show elevated headspace readings and no VOC <br /> compounds of concern were identifled above laboratory reporting llmits, Total PCBs were <br /> identified above the residentlai regulatory Ilmit in one test plt sample. Low level PAFEs and <br /> low concentrations of DRO in the soli were identif�ed within the debrls at the Subject <br /> Property. <br /> If you have any questions about this report, please contact Michelle Hosfield at 651-395- <br /> 5224. <br /> Slncerely, <br /> WENCK ASSOCIATES, INC. <br /> � � � ~ <br /> Kelly]aworski Michelle L Hosfle[d <br /> Environmental Scientist Environmental Scientist/Associate <br /> En�losures: Figure 1: Site Location Map <br /> Table 1: Soll Analytical Summary <br /> Attachment A: TestAmerica Laboratory Analytical Reports <br /> 3 <br /> �lMoalbury-Arllwoodbury\Terhnlml15503 Lab WMtW1-Cbkqer EstaM\Tldi R�amo�slnyer tecMlml m�mo.tlea� <br />
