Suncor working to expel cancer-causing benzene from under Denver-area refinery
Suncor Energy has expanded the hose system blowing air bubbles into Sand Creek attempting to expel cancer-causing benzene spreading from under the company’s oil refinery north of Denver.
Its crews also have been packing a trench with bentonite clay from Wyoming, focused on meeting a deadline today for the completion of a 1,000-foot-long, 30-foot-deep underground wall designed to hold back contaminated groundwater.
