After preliminary work that began three years ago, the U.S. Environmental Protection Agency this week issued an administrative order to officially start the cleanup of the Gowanus Canal Superfund site in Brooklyn, N.Y.
The latest $125-million work segment will involve full-scale dredging and capping of the upper third of the 100-ft-wide, 2-mile-long canal and restoration of another area, according to EPA. The entire project is valued at $500 million, ENR reported earlier.
