Aberjona River

Aberjona River is a short urban river located in the northwestern suburbs of Boston, flowing through several towns in Middlesex County, Massachusetts. It is a principal tributary of the Mystic River, ultimately draining into Boston Harbor and the Atlantic Ocean. The river's watershed has been a site of significant industrial activity and subsequent environmental remediation efforts, particularly related to groundwater contamination from historic manufacturing.

Course

The Aberjona River originates from a network of wetlands and springs near the border of Reading, Massachusetts and Wakefield, Massachusetts. It flows generally southward through the Upper Mystic Lake, which is formed by the Winchester Dam in the town of Winchester, Massachusetts. From the lake, it continues south, passing through the Horn Pond area in Woburn, Massachusetts, before its confluence with the Mystic River near the border of Arlington, Massachusetts and Medford, Massachusetts. Major tributaries include Whittemore Brook and several smaller streams that drain the surrounding urban landscape of the Boston metropolitan area.

History

The river valley was historically inhabited by the Pennacook people prior to European settlement in the 17th century. The area saw rapid industrialization in the 19th and early 20th centuries, particularly in Woburn, Massachusetts, which became a major center for the American leather industry and chemical manufacturing. Operations by companies like the W. R. Grace and Company and UniFirst Corporation led to severe contamination of the river and its underlying aquifer. This pollution was central to the landmark environmental law case detailed in A Civil Action, which involved the United States Environmental Protection Agency and the Woburn, Massachusetts leukemia cluster. The Superfund program later designated areas within the watershed for cleanup.

Ecology and environmental concerns

The river's ecosystem has been heavily impacted by centuries of urban development and industrial pollution, including heavy metals like arsenic and chromium, and volatile organic compounds such as trichloroethylene. These contaminants originated from numerous former industrial sites, including tanneries and chemical plants in Woburn, Massachusetts. Restoration projects led by the Environmental Protection Agency, the Massachusetts Department of Environmental Protection, and local organizations like the Mystic River Watershed Association have focused on sediment remediation, stormwater management, and habitat improvement. Fish populations have been affected, and advisories regarding consumption have been issued by the Massachusetts Department of Public Health.

Recreation and access

Despite its history, portions of the Aberjona River corridor offer recreational opportunities within the highly developed suburban landscape. The Aberjona River Pathway and the Winchester portion of the Southern New England Trunkline Trail provide walking and biking access along sections of the river. The Upper Mystic Lake is used for sailing and boating, managed by the Mystic Lakes Sailing Association. Other nearby green spaces include the Horn Pond conservation area in Woburn, Massachusetts and the Middlesex Fells Reservation, which is part of the Metropolitan Park System of Greater Boston.

In popular culture

The Aberjona River and the environmental tragedy in its watershed gained national prominence through the non-fiction book A Civil Action by Jonathan Harr. The book was later adapted into a major motion picture starring John Travolta and Robert Duvall, which depicted the federal court case against W. R. Grace and Company and other parties. The story brought significant attention to issues of toxic tort law, corporate responsibility, and the work of the Environmental Protection Agency.
