The Paskamanset and Slocums River really form just a single river, but the freshwater portion kept its earlier Native American name, while the salt-water portion is named for early English settlers, the Slocum family.
It runs through Dartmouth, passing under U.S. Route 6 and the town's former dump, and heading toward Russells Mills, and eventually drains into the Slocums River, with an associated floodplain in Apponagansett Swamp.
The river has been polluted for some years, mainly by pathogens and overly high nitrogen levels.
It was closed in 1995 and capped to prevent future contaminated runoff, but decades of waste have been leaching into the river.
