Photo by Pete McBride @pedromcbride | Each year 13 billion gallons of snowmelt water—supplying 7 percent of Denver’s needs—flows into or around the treatment ponds above the Blue and Eagle River tributaries (for the Colorado River) and the Arkansas River Valley. The Climax open-pit mine near Leadville, Colorado, extracts molybdenum and has released “spikes” of molybdenum at levels up to 14 times higher than the state limit into the watershed. Climax has requested multiple extensions for the temporary lifting of those health limits, and water-quality scientists hope the mine will use the extension time to stop the molybdenum pollution spikes. The constant push and pull serves as a reminder of the fragile balance between mineral extraction and clean water in the Colorado River Basin.
