Leave it to the Department of Energy to make a tourist site of a toxic dump. It started life (or death) as a munitions plant during World War II. The Atomic Energy Commission -- one of the forerunners of the Department of Energy -- took it over in the mid-1950s to process uranium, adding radioactivity to the toxic sludge. Then the Army had plans to produce Agent Orange defoliants there. The whole thing became a Superfund site in the 1980s. They buried the stuff under 75 feet of dirt and built a viewing platform on top of it, with picnic tables and hiking trails. The Visitors' Center explains how safe the site is now. It is less than a mile from the water supply for 70,000 people and from the Francis Howell High School. Wear your lead underwear.
