At its busiest, as many as 100 ships a day transported cargo through it. [63] The Gowanus Canal has 14 combined sewer overflow points. In the middle and upper segments of the canal, where liquid coal tar has seeped into the natural sediment, the EPA would stabilize that sediment by mixing it with concrete or similar materials.

[76] In 2014, the EPA presented a proposal for containing toxic sludge in the Gowanus Canal. This culminated in an incident when a city worker dropped a manhole cover, severely damaging the pump system, which was already suffering from the effects of the corrosive salt water.

[24], In 1887, the New York State Legislature closed the Bond Street outflow point.
