POSTMEDIA NEWS WINDSOR, Ont. -- The mysterious hum in the southern Ontario city of Windsor that has tormented thousands of residents is real and the likely source is a blast furnace on Zug Island. A new $60,000 report by the Department of Foreign Affairs and International Trade confirmed the hum's existence, which it found was coming from Zug Island at the intersection of the Rouge River and the Detroit River. “The scientists were able to hypothesize that the source of the hum is the blast furnace at U.S. Steel,” said Jeff Watson, Conservative MP for the Ontario riding of Essex, in an interview with the Windsor Star in late May. “However, they weren’t able to conclusively confirm that.” Watson said the government is treating this seriously, sending letters to U.S. Steel and the U.S. government. He added that his government is looking into whether there can be a "noise treaty," as there are already binational agreements on air and water quality. While Windsor Counc. Al Maghnieh is pleased the bothersome buzz he and others were ridiculed about has been found to be real, he says the report “was whitewashed” and is upset it doesn't pinpoint a source. “Verbally, they hypothesize that it’s U.S. Steel but they’re not prepared to put that in writing. There are fingerprints of political influence all over this report," he said. “The feds hung on for so many months before releasing it so I’m wondering if it was edited.” The low-frequency hum has bothered residents from the west end of the city at different times of the day, some who experience headaches and earaches. The hum can wake up residents, shake windows and clink wine glasses, said Windsor resident Mike Provost. United States Steel, which produces steel products in Canada, the U.S. and Europe, did not provide a comment as it didn't see the report. Scientists are looking to do more investigations to pinpoint the source of the hum. "I’m certainly disappointed that we didn’t conclusively find the smoking gun,” said Colin Novak, the University of Windsor scientist who led the study with Peter Brown from Western University. “The hum is something that I had heard myself so I was very curious to find out what the source was, as well. “Looking at what’s on Zug Island, it’s very likely that it’s a blast furnace.” Windsor West NDP MP Brian Masse, the federal critic on Canada-U.S. border relations, is disappointed with the report. “I had hoped there would be a specific source, but also a specific action plan, and an explanation of why it took so long to go public,” Masse said.
