A plan to bury low level radioactive waste 680 metres underground at the Bruce Power site on Lake Huron, is running into opposition from the Council of Canadians.
It warns that "extreme caution is needed when nuclear waste and freshwater are involved."
Ontario Power Generation wants to store up to 200 thousand cubic metres of radioactive waste in a network of tunnels and caverns.
Council of Canadians spokesperson, Emma Lui tells Bayshore Broadcasting news, some of this material will be around for hundreds of years.
Lui says there are plans for public meetings in Canada next year (2012) .
The OPG nuclear waste repository could be open in 2013 and would start receiving waste by 2018.
The Council of Canadians also warns that once the site is open, OPG may start storing high-level radioactive waste.
That she says would pose an even greater threat to the drinking water of millions in North America.
However, an official with the Nuclear Waste management Organization denies there ever be any high level radioactive waste stored at the site.
