Wild-salmon researcher Alexandra Morton has posted a troubling video on her blog.
It shows blue film on the Quesnel River not far from where a tailings dam breached at the Mount Polley Mine.
“I’m on a dock in Likely looking at a blue film just pouring down against this wire on the deck and on down to the bridge down the Quesnel River into the Fraser River," Morton says in the video. "This blue film is some kind of flocculent or some kind of chemical from the mine. It is pouring into the Fraser River, whatever it is."
On her blog, Morton wrote that this film "burns your skin like a jelly fish sting".
She collected a concentrated sample in a plankton net so it could be subjected to laboratory analysis.
"A small crowd collected and everyone could see it," she added. "What is this? What is it doing to the Fraser River. I have received reports since the first days after the tailing pond burst that the water far downstream has different colour."
Morton revealed that she had notified the Interior Health Authority, which sent an email thanking her for alerting officials to the existence of this blue film.
"I have contacted the Ministry of Environment who confirmed that they are aware of it," wrote Roger Penrose, regional director of health protection, "and that they have collected samples for analysis and would appreciate whatever assistance you can provide in getting this message to pepole who have suffered health effects from exposure to this substance..."
On her blog, Morton wrote that she didn't understand why the Ministry of Environment kept this information from the public.
