This isn't the only incident. The present attitude is to sit on it and try to contain it.
There are holding cells at Swan Hills that are leaking into the groundwater. Slave Lake is downstream and the residents have been fuming for years. The treatment plant has failed most of their burns - which means when toxic chemicals were to be completely oxidized by burning, they weren't. As a result, the dioxan and furan(for example) fallout around the plant has coated everything, prompting the ban on hunting and fishing around the plant.
Closer to home, there is the beloved Canada Creosite Site recovery plant on the Bow. They estimate there is a few million litres of creosote still underground. They choose the place where the bedrock is lowest and began pumping water out from there. The groundwater flow in the area is altered so there is a net migration to this particular bedrock pool. Now, everybody knows creosote is not water soluble. So they will NEVER recover most of it. They have contained it for the time being with concrete walls along the Bow. How long will the concrete hold? It would literally cost billions to dig it all up and process it properly, not to mention the disruption to business and traffic in the area. So, here we sit with this present attitude for these problems.
Will we ever learn? You would think so, but it ain't happening. A few more examples?
The railway yards in Ogden. They are still in operation. The entire site is rife with toxins. Again, the solution is containment. Why don't we get after CP now to clean it up while they're still in business? Politics.
Not far from there is the IKO asphalt shingle plant. Their employee safety record is atrocious. Drive by and read the sign that says 'We have worked _______ days without an accident'. Were it not so sad it would be a joke. The smell is gross. Now, with a record like that, do you really think they are responsible environmental stewards? Again, they're not going to clean up the area while the plant is still operating. Catch 22 - when the plant is no longer operating it will be because they went bankrupt. Who cleans up the mess?
Well this has got me in a good mood. Have a nice day.
Cheers
