But sulfide-ore copper mining presents more serious risks, such as acid mine drainage, and it would introduce risks in and around the Boundary Waters—the area that represents and produces those high-quality natural values that are the foundation of the region's new economy.
The human health impact of proposed sulfide-ore copper mines must be fully evaluated to prevent creating major threats to public health. Sulfide-ore copper mining has the potential to release numerous chemicals known to negatively affect human health, including mercury, arsenic, lead, asbestos-like fibers, and air pollution.
