DuPont Explosives Plant Site, Washington

The DuPont de Nemours Company operated an explosives plant at this site for 70 years, until it closed in 1975, after which the property was sold to the Weyerhaeuser Corporation. Both companies are involved in the clean up of the contaminated plant site, and only a few outbuildings have been left standing. Within the controlled clean up area is the site of the original Fort Nisqually, a Hudson Bay Company post established in 1833, and considered to be the first non-native settlement in Puget Sound. The fort has been reconstructed at Point Defiance Park near Tacoma. The old company town of DuPont, which housed workers for the plant, is still in tact, surrounded by a new urbanist development called Northwest Landing, built by Weyerhaeuser.
