See Section 2.2.1 & 2.2.2.
2.2.2 Issues
Additional confirmatory samping was conducted which revealed elevated concentrations of PCBs in soils on the east side of the building and underneath the building foundation. Groundwater sampling from groundwater probe GP-12 within the building footprint showed PCB (Aroclor 1242) contamination of 110,000 mg/kg. See figures in 'documents' section of website for details of data/results. This data was presented to City and State officicals on 1/21/2015.
