BUFFALO, NY - Congressman Brian Higgins sent a letter to the EPA asking the organization to investigate the Niagara Falls sewer discharge into the lower Niagara River on Saturday, July 29th.

The discharge, which entered the water from a tunnel not far from the Maid of the Mist docks, emanated from the Niagara Falls Waste Water Treatment plant on Buffalo Avenue, according to the water board's Executive Director Rolfe Porter, who said it was the result of some work being done to maintain one of its sediment tanks.

"Part of the process requires us to back wash our filters,” Porter told 2 On Your Side. “Our filters are carbon filters so they're black. When we back wash those filters, our back wash water is black."

Governor Andrew Cuomo has also directed the state DEC to conduct its own investigation.
