Indigenous communities, environmental groups and other concerned citizens who monitor toxic waste are increasingly concerned about the dumping of radioactive matter and other contaminants into the Ottawa River from an inactive nuclear reactor northwest of the capital.
A scientific report released in February details the dumping of thousands of litres of water contaminated with radioactive tritium, PCBs and other toxins into the river from the inactive nuclear power demonstration (NPD) reactor in Rolphton. Ont., about 200 kilometres from Ottawa.
The contaminants are at levels above Ontario and Canadian surface water quality standards, according to the report.
