QuoteAn estimated 10 million cubic metres of water and 4.5 million cubic metres of toxic waste — equivalent to 2,000 Olympic-sized swimming pools — spilled into Hazeltine Creek, Quesnel Lake and Polley Lake when the tailings pond failed early Monday morning. The waste water has caused Hazeltine Creek to expand from just over one metre to nearly 46 metres.



"Polley Lake rose about 1.5 metres above its normal height and steps are being taken to pump some of that water into the springer pit so we can start dropping that water level back to normal," says Kynoch.



everal employees of the mine, who wished to remain anonymous to protect their jobs, have told Global News the same tailings pond had a minor breach three months ago.



But Kynoch says the dam has never failed before.



Common minerals and elements found in tailings, which is the waste material left over from the extraction of metals, can include arsenic, mercury, sulfur and cyanide.



"We have never detected mercury in the tailings pond at Mount Polley," says Kynoch. "There's no mercury there."



"Another one I've heard talked about is arsenic. Arsenic levels are one-fifth of drinking water."



He adds that the company regularly performs toxicity tests on the water in their tailings facility and it is not toxic to rainbow trout, which spawn there.

An Environment Canada filing from Mount Polley Mine lists all the substances disposed of in the tailings pond – including manganese, cadmium, phosphorous and mercury.



But it is not known how mobile those substances are.



Substances listed as disposed "on-site" in Imperial Metals' 2013 Mount Polley Mine report (Note: It's unclear how mobile these solids were, how much was in water, if any, and how much spilled as solids, if any)



Phosphorus – 41,640 tonnes

Manganese – 20,988 tonnes

Copper – 18,413 tonnes

Vanadium – 5,047 tonnes

Zinc – 2,169 tonnes

Cobalt – 475 tonnes

Nickel – 326 tonnes

Antimony – 14 tonnes

Arsenic – 406,122 kg

Lead – 177,041 kg

Selenium – 46,136 kg

Cadmium – 6,487 kg

Mercury – 3,114 kg

Kynoch says "Imperial accepts that it is our responsibility to put this right."



"Our first priority was, and continues to be, the health and safety of our employees and our neighbours. So we have to work hard to make sure we don't hurt anyone," he adds.



"If you had asked me two weeks ago if that could happen, I would say it couldn't happen."



Since the news of the tailings pond breach, the shares of Imperial Metals Corporation have dropped 42 per cent.

Quote from: "Real Woman"This is the problem.  No one means for this stuff to happen but it isn't uncommon in the least.

Planes can crash, ships can sink, trucks can get in accidents, trains can derail, infrastructure like bridges can collapse. At least nobody was hurt(that I'm aware of). The toxic waste can and will be cleaned up. Sports fishermen and holidayers don't like things like mines, factories and pulp mills, but they provide much better jobs than pandering to tourists.



BTW, how far is that mine from your place?

QuoteConcerns raised in a report three years before a massive tailings pond breached at the Mount Polley gold and copper mine in central British Columbia were "basically ignored," said a First Nations leader whose territory has been soiled by the disaster.



Bev Sellers, chief of the Xatsull First Nation, also known as the Soda Creek Indian Band, said many members of her band were in tears when they learned of Monday's release of a slurry of contaminated water and mine waste into several local waterways.



"Because they know the destruction that's going to happen from this breach. It's just a real sad day," she said in an interview Tuesday.

QuoteThe company also said, "Monitoring instruments and onsite personnel had no indication of an impending breach."



But Brian Olding, an environmental consultant who examined the Mount Polley mine tailings pond, says the storage facility was growing at an unsustainable rate.



He says Imperial Metals was building the walls of the storage dam higher and higher to hold back the contaminated water, and was seeking a permit to treat and release some of the water to keep the size of the pond in check.

I understand the job perspective and I don't jump up and down over mining like some.  The trouble is, to you and so many others reading this story it's a "clean up on aisle 2" situation.  It's not that simple.  There will be no reversing this completely and that's the thing some people don't seem to understand.  You can't just take it back.  This is why people don't want these industries.

Disasters like this are only becoming more common because these companies only care about profits. Rarely a day goes by now without hearing about leaks and spills.

QuoteThe president of Imperial Metals says the water from the tailing pond was "very close to drinking water quality". Really? The pond had 26 tonnes of nickel, over 400,000 kilograms of arsenic, 177,000 kilograms of lead and 18,400 tonnes of copper in it. Who wants Kool-Aid?

Actually, it can and will be if done right. All those nasty-ass toxic chemicals you saw listed can occur almost anywhere. They are concentrated when they come out as waste from a mine's tailings pond. Once the sediment settles and is separated from the water rainbow trout(yuck, worst fish I have ever eaten), will not even have this season's spawn interrupted.



It really is much ado about nothing. I can think of so many more potential environmental problems than this one that do NOT get covered by the press.

Quote from: "Real Woman"
Yeah they said that here too and now the Americans are complaining about higher cancer rates and other unexplainable disorders.  I know people who have challenged kids from heavy metal poisoning.



I grew up near tailing ponds.  I've seen them with my own eyes.  I've heard about them leeching many many times.  



The effects of these types of accidents are wide spread and long term.  You are deluding yourself if you think otherwise.
