Heavy equipment moves contaminated dirt at the site of the old Ward Transformer facility near the RDU Airport in Raleigh Tuesday afternoon August 5th, 2008. The site is a Superfund cleanup site; about 150,000 tons of ground were soiled by the PCB's in the transformers. Contaminated soil is dug up and heated in a giant industrial dryer, causing the pollutants to vaporize. In a second step, the PCB vapors are destroyed in an afterburner and the gases scrubbed and vented through the stack.
