Denison Environmental Services (DES) has been engaged in numerous mine site cleanup and decommissioning projects that really showcase our strength implementing closure plans. As a result of these successes DES is also involved in planning and consulting work to assist mines with mine closure estimating and compliance projects.

Once safety and physical stability issues are addressed, the longer-term monitoring and rehabilitation work to address the chemical stability begins. DES has a well-structured approach to ensure regulatory compliance. Environmental performance objectives along with worker safety are given the highest priority.

Much of our current workload is focused on the closure stage of the mining cycle. As a society, we have learned that irresponsible mining is not a sustainable venture. DES has become a leader in responsible closure implementation specializing in mine care and maintenance. ISO 9001:2008 (Elliot Lake) certified.
