What part of the Assabet River National Wildlife Refuge was formerly used as a dumping ground by the Natick Laboratories until the 1980s?
Fort Devens-Sudbury Training Annex The Fort Devens-Sudbury Training Annex was a former annex of Fort Devens that was operational from 1942 to the 1990s. It originally opened as an ammunition dump for the base, and old railroad lines and bunkers can still be seen in the area. It then functioned as a dumping ground for the Natick Laboratories until the 1980s. In the 1990s, the site was cleaned up and turned into the Assabet River National Wildlife Refuge.
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.
