The supplemental Phase I completed with FY19 assessment grant funds was for tax parcel 010-0019-00020 only. The supplemental Phase II investigation included the following primary tasks to achieve the project ive of determining the nature and extent of environmental impacts that may be encountered during road and utility construction activities and the redevelopment of the southeast parcels: ? Sampling of surface and subsurface soil through the installation of Geoprobe soil borings. ? Sampling of shallow groundwater on-site encountered in soil borings. ? Completion of excavation test pits to define the extent of potential foundry sand contaminated with high levels of arsenic within the development area. Surface and Subsurface Soil Sampling: Due to budget constraints WESTON was limited to four field days. For that reason, soil borings were installed based on the priorities for data collection set forth by DEDA during the June 2, 2010 conference call. Additional detail regarding sampling priorities was provided by Barr and DEDA in a Technical Memorandum Tech Memo dated June 16, 2010. Soil borings UAS-SB01 through UAS-SB23 were advanced at the Site between July 6 and July 9, 2010. In accordance with WESTON?s SAP amendment dated June 28, 2010 and Barr?s Tech Memo dated June 16, 2010 a minimum of one soil sample was collected from each soil boring for laboratory analysis. All soil samples were submitted to Pace Analytical Services, Inc. Pace in Green Bay, Wisconsin. All soil samples were analyzed for polychlorinated biphenyls PCB, Resource Conservation and Recovery Act RCRA metals plus copper and zinc, and pH analysis in accordance with the approved SAP. In addition, as described in the approved SAP amendment, soil samples UAS-SB01, UAS-SB03, UAS-SB04, UAS-SB06, UAS-SB08, UAS-SB11, UAS-SB12, UAS-SB15, UAS-20, UAS-21, and UAS-SB23 were submitted for laboratory analysis of volatile organic compounds VOCs, polycyclic aromatic hydrocarbons PAHs, and diesel range organics DRO. Soil sample analytical data for all compounds were compared to the following Minnesota Pollution Control Agency MPCA Soil Reference Values SRVs: ? Tier 1 Residential SRVs, ? Tier 2 Industrial SRVs, ? Tier 2 Recreational SRVs, and ? Short Term Worker SRVs. Arsenic and copper exceeded the above referenced MPCA SRVs. Soil borings logs and field notes are provided in the Phase II Letter report. Groundwater Sampling: Perched groundwater was encountered at four of the soil boring locations and temporary monitoring wells were installed in accordance with WESTON?s approved SAP amendment. Temporary monitoring well samples were collected and sent to Pace for laboratory analysis. Temporary monitoring well UAS-TMW02 was sampled and groundwater submitted for VOC, DRO, PAH, PCB, RCRA Metals plus copper and zinc, and pH analysis in accordance with the approved SAP Amendment. Because of very slow recharge of temporary wells UAS-TM03 through UAS-TM05, these wells were only sampled for RCRA metals. It was decided during a call between WESTON and Barr personnel on July 8, 2010 that RCRA metals was the most important analysis to complete therefore, the temporary monitoring wells at the above locations were purged dry and allowed to recharge prior to sample collection. The groundwater analytical data for all compounds identified above the laboratory detection limits were compared to the Minnesota Department of Health Health Risk Levels HRL and the U.S. EPA Maximum Contaminant levels MCLs. Arsenic, Barium, Cadmium, chromium, copper, lead, mercury, and zinc were identified above the MCL. Excavation of Test Pits: WESTON contracted with Range Environmental Drilling to complete the excavation of test pits in accordance with the approved SAP amendment on July 7, 2010 with one exception. Test Pit ID UAS-TP02 was not completed because of an access/property boundary issue brought up by CN Railroad. Barr conducted oversight and documentation of the test pit excavations. Bay West collected one so
