Energy Net on 27 Sep 09Steam-cleaning technology created by Lawrence Livermore National Laboratory was used to clean a Superfund site in Visalia, in California's Central Valley - and the job was finished a century earlier than first expected. Utility company Southern California Edison used the site to soak wooden utility poles in creosote and other protective chemicals for some 80 years. Those chemicals contaminated the soil and underground water in the area. By the 1970s, the chemicals had seeped down as much as 100 feet in places. The site, called the Visalia Pole Yard, was one of the first Superfund sites, part of a federal government cleanup program for very toxic places. Superfund sites are on the National Priorities List of the Environmental Protection Agency because they may seriously threaten public health.
