The 14-acre Halby Chemical site encompasses a chemical storage facility and associated warehouses in Wilmington, New Castle County, Delaware. Land use in the area is primarily industrial. Storm water runoff from the site generally flows toward a drainage ditch which discharges into the Christina River. The plant then closed in August 1977. Since 1977, Brandywine Chemical Company has used the site to receive and distribute bulk chemicals. As a result of citizen complaints about lagoon overflow, hydrogen sulfide-like odors, and numerous spills, a number of investigations were conducted. The selected remedial action for the site includes consolidating debris onsite or disposing of all debris offsite; excavating and stabilizing the top 6 inches of approximately 10,300 cubic yards of contaminated surface soil in the process plant area, followed by replacing the stabilized soil onsite; capping the approximately 5,800 square yards residuals area with an asphalt cap; and conducting soil monitoring.
