Kalakaket Creek RRS - Drum Storage Area 2
Past Work on Site
PCBs, and dieldrin and diesel from leaking drum storage. Contaminants exceed migration to groundwater, but groundwater samples were collected and contamination was not detected. The remedial action conducted in 2009 removed PCBs in soil, confirmation samples were below 1 ppm. Diesel contamination to ~ 2,000 ppm was detected in confirmation samples at the limits of the western excavation, and 327 ppm in the eastern excavation. Since groundwater contamination was not detected at the site, subsurface soil contamination below health based levels will not require institutional controls or long term monitoring. The 2010 Record of Decision identifies the selected rememdy for this site to be source removal and offsite disposal of PCB, dieldrin, and 1,2,3-TCP contaminated soil.
