Know the Issue: Sulfide-ore Mining Creates Unacceptable Risks to BWCA

The science is clear: allowing sulfide-ore mining next to and upstream from the Boundary Waters Wilderness would threaten it for generations. In our new scientific report, we summarize the best scientific research on this issue and outline the ways sulfide-ore mining would harm the Boundary Waters Wilderness, whether by contaminating its water or destroying the surrounding forest. In our report, we also share the conclusions scientists and experts in their fields have made regarding the risks from this type of mining.

"If sulfide mines are developed in the Rainy Headwaters [part of the Boundary Waters watershed], it is not a question of whether, but when, a leak will occur that will have major impacts on the water quality of the Boundary Waters Canoe Area Wilderness."
-- Dr. Myers, hydrologist

"It is not feasible, given today’s or tomorrow’s technology, to reduce the risk of impacting waters downstream from a copper/nickel mine in a sulfide ore body to zero."
-- Dr. Chambers, mining expert
