With winter having come to a close, people living near the Rocky Mountains will have to reckon with the effects of snow contamination, an enduring issue magnified by mining activities in the region. A new study provides an unprecedented look at the heightened levels of contaminants that have been carried to the Rockies by winter storms.
The study, recently published in the journal Environmental Pollution, has pinpointed mining operations in the Pacific Northwest as the source of contaminants. Mercury and other metals from these mines have been infused into snow that accumulates in the northern range of the Rockies. Since the western U.S. heavily relies on mountain snowpacks for water, increased snow contamination could entail dire consequences in the near future.
The Significance of Snowpack
Iconic winter pastimes in the western U.S., like skiing and snowboarding, wouldn’t be possible without mountain snowpack, which builds up and eventually melts by spring and summer. But the importance of snowpack extends beyond recreation, as it provides the region with water for hydropower, agriculture, and household use for millions of Americans.
