Constructed Wetland Design and Optimization for Metal and Metalloid Treatment at the Minto Mine, in the Yukon, Canada

Constructed wetland treatment systems (CWTSs) can treat various contaminants in
water when designed and executed in a scientifically guided manner. A site-specific
CWTS is being developed for Capstone Mining Corporation’s Minto Mine (Yukon), using
a scaled phased approach to allow for flexibility for modifications and optimisations
along each step. The phases are: (1) site assessment and information gathering, (2)
technology selection and conceptual design, (3) pilot-scale testing and optimisation
(controlled environment), (4) onsite demonstration-scale confirmation and optimisation
and (5) full-scale implementation. The first three phases have been completed
successfully, and a year of testing performed on site for Phase 4.
