KIVALINA (AP) -- Crews have completed the clean up of a site near the Cominco Red Dog Mine after a truck overturned and spilled approximately six tons of zinc concentrate, officials said Wednesday.
During the accident last Friday, a Nana-Lynden Transport truck overturned in bad weather, spilling zinc concentrate over a 10-foot by 20-foot area of road gravel and tundra.
Tarps were placed around the spill site to keep the powdery substance from blowing away but weather delayed cleanup of the site, the Alaska Department of Environmental Conservation said.
The spilled produce and contaminated snow and soil were brought back to the mine and reintroduced into the milling process.
DEC said soil samples will be taken to determine if more extensive measures are needed. This spring, an X-ray spectrometer will be used to determine if the contamination extends beyond the spill site.
