Pantex is the nation’s only plant for assembling and disassembling nuclear weapons.  The plant was added to the national Superfund cleanup list because of past site practices of burning chemicals in unlined pits, burying waste in unlined landfills, and discharging waste into on-site surface waters known as playa lakes in 1994.  The first five year review of the site was recently completed, and it appears efforts to clean up soil and groundwater contamination have been effective according to The San Jose Mercury News.
