The report is dated February 6, 2013, and contains a Phase I assessment of the site, as well as analytical testing results. According to the report, 11 soil samples were taken between two and six feet below ground surface, and then analyzed for diesel-range organics (DRO) and residual-range organics (RRO). Eight of the 11 soil samples contained DRO concentrations above DEC's migration-to-groundwater (MTG) cleanup level, with the maximum found concentration at 42,400 mg/kg.
