In 2013, MassDEP conducted sediment core sampling to further evaluate PCBs in Neponset River sediments at four areas along the Neponset River. We’ll turn the streets of Cambridge into the end of the rainbow. In 20, Massachusetts Department of Environmental Protection (MassDEP) oversaw a large removal of contaminated sediments in Mother Brook, which feeds into the Neponset River. According to the USGS report, the PCB concentrations substantially increased in sediment core samples collected downstream of the Mother Brook confluence. The site is bordered by residential, commercial, industrial, and public parcels of land, including the Neponset River Greenway.įrom 2002 through 2006, the United States Geological Survey (USGS), in cooperation with the Massachusetts Executive Office of Environmental Affairs Riverways Program and the EPA, conducted studies which included the Lower Neponset River in Boston and Milton. The Lower Neponset River channel ranges from approximately 40 feet to 300 feet wide and comprises an estimated 40 acres within or bordering the City of Boston (Hyde Park, Mattapan and Dorchester sections) and the Town of Milton, MA. Based on preliminary studies, this portion of the river contains sediment contaminated with elevated levels of polychlorinated biphenyls (PCBs). The Lower Neponset River site consists of a 3.7-mile section of the Neponset River between its confluence with Mother Brook (in Hyde Park, Massachusetts (MA)) and the Walter Baker Dam (in Dorchester/Milton, MA).
