Contaminated Sites Staff recieved the Biocell Area Drum Characterization report dated March 2012 in our office on April 2, 2012. The report details the findings of the Drum Characterization work performed within the boundaries of the biocell area. Several of the drums contained metals adn pesticides that require off-site shipment and disposal. Several of the drums contained petroleum hydrocarbons at elevated levels, and those soils will be treated in the biocells with available capacity this summer. Some of the drums contained soils that were not impacted above cleanup level for the contaminants of concern. The contents of these drums were spread out on site. |
