Denison Environmental Services (DES), a division of Denison Mines Inc., is a trusted industry leader in long-term care and maintenance for closed mine sites.

As mining regulations and environmental awareness evolved over the last several decades, a need for planning closure procedures for these mines also developed—a practice that has become a mandatory part of the opening of new mines. Denison Environmental Services was created to address these needs and requirements.
