Industri-plex, Massachusetts

Merrimac Chemical Co. and its successor, Monsanto Co., take the blame for this toxic place. Just 12 miles from Boston, Industri-plex was a plant for manufacturing everything from insecticides and explosives to acids and countless other chemicals. The site represents about 130 years of chemical manufacturing overall, and has been leaching dangerous pollutants for at least that long.

To make matters worse, the site exudes a pervasive "rotten egg" odor due to hydrogen sulfide gas generated by the decay of the buried animal hides from glue-manufacturing wastes.

Industri-plex was designated a Superfund site in 1981, and cleanup efforts have been extensive. The site now houses a regional transportation center (inset photo) and a Target store.
