The Blackstone River is a river in the United States that flows through the states of Massachusetts and Rhode Island. It is 48 mi (77 km) long with a drainage area of 540 sq mi (1,400 km2) and drains into the Seekonk tidal river at Pawtucket, Rhode Island. Its long history of industrial use has caused significant pollution, with the United States Environmental Protection Agency describing it as “the most polluted river in the country because of high concentrations of toxic sediments.”

Rhode Island is a state in the New England region of the Northeastern United States. It borders Connecticut to its west; Massachusetts to its north and east; and the Atlantic Ocean to its south via Rhode Island Sound and Block Island Sound; and shares a small maritime border with New York, east of Long Island. Rhode Island is the smallest U.S. state by area and the seventh-least populous, with slightly fewer than 1.1 million residents as of 2020; but it has grown at every decennial count since 1790 and is the second-most densely populated state, after New Jersey. The state takes its name from the eponymous island, though nearly all its land area is on the mainland. Providence is its capital and most populous city.
In 1636, Roger Williams and his followers founded the settlement of Providence Plantations.
