Opposition Mounts Against Waste Dum

Protestors backed by opposition parties pressed the government to overturn regulatory approval for a nuclear waste dump upriver from Canada's capital, fearing the contamination of its drinking water.

Indigenous chiefs and elders, leaders of the Bloc Quebecois and Green Party, and several environmental groups are pushing back against a Canadian Nuclear Safety Commission decision last month to approve the waste site in the town of Chalk River, 180 kilometers north of Ottawa.

The river provides drinking water to the capital's more than one million residents and 140 nearby communities.

The tribe has launched one of several legal challenges of the project.

That any river pollution could lead to health issues and spoil habitat for bears and a number of at-risk animal and plant species.

The disposal facility at Chalk River Laboratories is to store up to one million cubic meters of nuclear waste.

Chalk River Laboratories was built in 1944 and was the site of the world's first nuclear reactor meltdown in December 1952, and saw one again in 1958.

Before being decommissioned, the lab developed nuclear reactors, conducted nuclear weapons research, and was at one time a major supplier of medical isotopes used to diagnose and treat cancers.

The Canadian Nuclear Safety Commission said in a statement that it would store mostly contaminated materials from environmental remediation and the decommissioning of the site in 2018, as well as from its past operations as a nuclear laboratory.

Waste from hospitals and universities would also be shipped there to be stored in the "containment mound."
