Recovery Act Workers Reduce Contaminant Levels Sharply in Portsmouth Site ‘Big Dig’
Recovery Act workers have reduced contaminant levels by 96 percent in soil 30 feet below ground in what has been coined the Portsmouth Gaseous Diffusion Plant’s “Big Dig.” In the $34 million Recovery Act project, workers are excavating a 70,000-square-foot area of soil with a high concentration of trichloroethene (TCE) under a now-defunct holding pond. The chemical compound was used as an industrial solvent at the plant, which enriched uranium for defense and commercial nuclear purposes until production ended in 2001.
