Covering tailings with soil and vegetation, adding lime to neutrize acid drainage, and red re- contouring waste pile to natural slopes can prevent long-term environmental damage. The use of constructted wetlands to treat acid drainage biologically has proven effective at many sites, converting reactive landscapes into functival ecosystems over time.
