Blackstone River

The Blackstone River in the United States is a river that flows through Massachusetts and Rhode Island. It is 48 mi (77 km) long with a drainage area of 475 mi2 (1229 km2). It drains into the Seekonk River at Pawtucket, Rhode Island. Its long history of industrial use in the watershed has caused significant pollution, with a 1990 report from the United States Environmental Protection Agency describing it as “the most polluted river in the country because of high concentrations of toxic sediments.”
