The natural gas company responsible for a hydrocarbon spill in Garfield County continues to clean up the mess. Over the weekend, an aeration and vapor extraction system was set up to rid the area of cancer-causing benzene. Aspen Public Radio's Marci Krivonen reports.
Donna Gray with the energy company Williams says the system erected Sunday is one of seven aeration and vapor extraction systems. The process is also called air sparging.
"That involves introducing air or oxygen to both the surface area and groundwater in the soil, in the spill area," Gray says.
