Disclosure of Non-Radioactive Contaminants in Port Hope

Canadian Nuclear Laboratories (CNL) is undertaking the Port Hope Area Initiative (PHAI) for the cleanup and safe management of historic low-level radioactive waste (LLRW) in the municipalities of Port Hope and Clarington. CNL is committed to providing timely and effective information to residents of the two municipalities and all members of the public.

Contractors working on behalf of CNL to undertake the radiological survey of properties in Port Hope occasionally identify the presence of actual or potential contaminants that are not part of LLRW.

CNL informs Port Hope residents on the results of these surveys, both radiological and non-radiological, once the nature of the contaminants has been verified through independent laboratory analysis. “Property owners have access to the detailed reports and are encouraged to discuss the results and raise any questions and concerns they may have with CNL staff,” said Craig Hebert, General Manager CNL’s Historic Waste Program Management Office. 

The PHAI is a very large and complex project with multi-test radiological surveys of approximately 4,800 properties in Port Hope and is being executed with care. 

If any contaminants not related to LLRW are found at higher concentrations than the standard, where one exists, CNL notifies the Municipality of Port Hope and the Ontario Ministry of Environment and Climate Change in addition to the homeowner.

For more information on non-radiological soil contamination, the following provincial organization can be contacted:
