Regional Profile

The Northeast Region is the most industrialized and populated of the four regions (with almost three million residents) and is comprised of 84 cities and towns situated in northeastern Massachusetts. The region spans from the New Hampshire border south through metropolitan Boston to Quincy and is bounded on the west by a line that extends roughly from Ashland to Westford.

The industrial base is mixed, ranging from high tech companies along Route 128 to durable goods manufacturing and petrochemical firms in the greater Boston area. The region also is home to a number of large power plants, major airports and seaports, and the transportation network that supports those facilities and links them with economic centers up and down the Eastern Seaboard.

Although chiefly urban and suburban, the region includes rural areas to the northwest and southwest of Boston. Its coastline, including Boston's inner harbor and Cape Ann, and nine river basins - Charles, Ipswich, Merrimack, Mystic, Neponset, Parker, Shawsheen, SuAsCo, Weir & Weymouth - are the region's predominant natural features.

Bacteria Source Tracking Program

Bacteria Source Tracking Reports

The Bacteria Source Tracking (BST) program was established at MassDEP's Northeast Regional Office in 2007. The goal of the program is to improve the water quality in pathogen-impaired water bodies by locating sources of bacteria pollution and recommending appropriate remediation actions. These reports detail the results of sample analysis conducted in the given year. Updated September 2009.
