• Some Lessons Learned:– Actual water quality impacts are often closer to pre-treatment
predictions than post-mitigation (i.e. treatments often fail to perform according to plan)
– Lack of adequate geochemical characterization is single greatest root cause of failure to predict impacts
– Hydrological failures are most often associated with predicting over dilution, failure to recognize hydrological features, or underestimation of water production quantities
– Mines in close proximity to water resources require more scrutiny

• St. Louis Watershed, MN– At river mile 171, wild rice dominates and sulfate = 2ppm– At river mile 120, mining sulfate discharges enter the
watershed– At river mile 100, there is
no wild rice, sulfate near 100ppm
– At river mile 20, there is a compromised stand of wild rice, sulfate = 15ppm

• 90% of wild rice waters ≤ 10ppm and “there were no large and important natural and self-perpetuatingwild rice stands in MN where the sulfate ion content exceeded 10ppm.” (Moyle 1975)
• Sulfates convert to hydrogen sulfide in sediments, especially under anaerobic conditions.

Mercury Effects
• Persistent bioaccumulative toxin• Accumulates more readily in muscle tissue of
fish and prey (NRC 2002)
• Passes more readily between placental and blood-brain barriers
• ↑Hg = ↓Cortisol ≈ ↓metabolism + ↓immune response + ↑blood pressure (Gump et al. 2012)
• 61% of Great Lakes study area > EPA human health criterion in 6 commonly eaten fish species (Evers et al. 2011)

“We are changing the Earth more rapidly than we are understanding it” (Vitousek et al. 1997)
• Economic model as driver a concern in Anthropocene – overlooks principal resources (e.g. water) and discounts waste generation
• Adaptation requires empowering communities with accurate science
• Public wellbeing requires balance between growth and regulation with holistic accounting of costs (e.g. waste, water use)

From just north of the Penokee Mountain area to Lake Superior, our Tribe is ready to stand up and protect Nibi (water) for all peoples and future generations.”
–M. Wiggins Jr. 2011
“It is only with a long-term perspective that we can identify which of the seemingly beneficial near-term actions truly contribute to long-term resilience and identify the ways in which some outwardly rational choices lead, in the end, to undesirable outcomes.”
