Fifty-five metal barrels, left for decades to deteriorate at the bottom of the Humber Canal, are seeing the light of day this week as Corner Brook Pulp and Paper undertakes a big cleanup. The debris predates the mill's current ownership under Kruger, but the company estimates they've been decaying since about the 1950s, although their presence went undetected until residents raised red flags two years ago. The 11-kilometre canal supplies the Deer Lake Powerhouse, which in turn generates electricity for the mill, and also does double duty as the town of Deer Lake's water supply.
