What part of the Assabet River National Wildlife Refuge was formerly used as a dumping ground by the Natick Laboratories until the 1980s?
Assabet River National Wildlife Refuge Assabet River National Wildlife Refuge, (formerly referred to as the U.S. Army's Fort Devens-Sudbury Training Annex), is a 2230 acre protected National Wildlife Refuge located approximately 25 mi west of Boston, and 4 mi west of the Eastern Massachusetts National Wildlife Refuge Complex Headquarters, along the Assabet River. It is located in portions of the Towns of Hudson, Maynard, Stow and Sudbury. The Assabet River National Wildlife Refuge consists of two separate pieces of land.

There is a visitor center located in the northern section, on Winterberry Way.
Bear Brook Watershed in Maine The Bear Brook Watershed in Maine (BBWM) is an experimental forest operated by the University of Maine in Hancock County, Maine, United States. The BBWM focuses around the two small first order branches of Bear Brook on the southeastern slopes of Lead Mountain above Bear Pond. Two years of monitoring studies began in 1987, after which the two watersheds of East and West Bear Brook were determined to be nearly identical. The West Bear Brook watershed has been experimentally acidified with ammonium sulfate every other month since November 1989 to study the effects of sulfur and nitrogen acid deposition. East Bear Brook has been used as an untreated reference. Related research topics at BBWM include climate change, carbon sequestration, base cation depletion, and watershed biogeochemistry. There are two USGS stream gauges on the East and West Branches of Bear Brook.
