Not unreasonable to presume that quite a bit of the multi-year sum of these byproducts (the list below shows the volumes from 2013), and who knows how many and what chemicals, have been released from its rocky prison of countless millennia to the tailings pond and as of yesterday into the Quesnel watershed.... >>>In filings made to Canadas National Pollutant Release Inventory in 2013 — which is only one years worth of data, but gives some idea of what the mines byproducts are — Imperial Metals recorded disposing of quantities of arsenic, lead, manganese, cobalt, mercury and other harmful mining byproducts. Mount Polley mine on-site disposal in 2013: Arsenic (and its compounds): 406 tonnes Lead (and its compounds) 177 tonnes Nickel (and its compounds) 326 tonnes Vanadium (except when in an alloy): 5,047 tonnes Zinc (and its compounds): 2,169 tonnes Cadmium (and its compounds): 6 tonnes Cobalt (and its compounds): 475 tonnes Phosphorus (total): 41,640 tonnes Copper (and its compounds): 18,413 tonnes Antimony (and its compounds) 14 tonnes Manganese (and its compounds): 20,988 tonnes Mercury (and its compounds): 3 tonnes Selenium (and its compounds): 46 tonnes Source: NPRI
