Opponents argue the project, a kilometre from the Ottawa River, poses risks to the drinking water supply for millions, will not safely contain the waste and the company failed to adequately consult many Algonquin Nations. Representatives from six concerned groups recently wrote an open letter to the federal government urging it to halt the project. The waste contains long-lived radionuclides, which many experts say require far more robust containment than this facility will offer.
Radionuclides are unstable, radioactive atoms. Some will remain radioactive for thousands or millions of years, while others are short-lived and decay quickly. The Environmental Protection Agency and other health organizations classify all radionuclides as cancer-causing.
