No mention of the treatment plant - but mention of the results from testing showing "concerning levels of heavy metal contamination surrounding the mine sites". I agree it would have been beneficial to be more accurate and descriptive as to what that means.
And quantifying the release of contaminants in discharge water is only the start - and not the end - of tracking those potential effects. Water quality guidelines only track the initial amount released as a % of the total water release - not the total accumulated amount nor especially the bioaccumulated amount in fish and other organisms. That's why those guidelines are inadequate and misleading.
That's a similar problem in Great Slave Lake and now Quesnel Lake.
