Whale Watching Above, Pollution Below
Could contamination from Victoria Harbour and the Gorge Waterway be harming Resident killer whales?
The scientifically defensible answer is yes.
Pollution from Victoria Harbour and the Gorge Waterway could be contributing to the cumulative contaminant burden, immune stress and reproductive difficulties affecting Southern Resident killer whales.
That does not mean the evidence presently proves that a particular chemical found in a particular whale came from a specific Victoria storm drain. Governments have never completed the matched source-to-food-web investigation needed to make that determination.
