The U.S. Environmental Protection Agency has started the cleanup of a superfund site near Moses Lake in central Washington. As correspondent Anna King reports, this restoration has been in the works for decades.
The contaminated area is made up of an old Air Force airport, a county airport and some adjacent lands. Dumpsites there are loaded with chemicals like PCBs, lead and petroleum. The EPA has started testing and designing a treatment system to remove trichloroethylene from the groundwater at the superfund site.
