Climate Models Call for Arctic Cleanup Action

Warming and precipitation increase groundwater pathways mobilizing contaminants from 2500 sites in Canadian High Arctic.
Climate projections predict permafrost thawing will accelerate groundwater movement and deepen active layers.
Researchers used SUTRA 4.0 to model groundwater flow at BAF-3 station on Brevoort Island, Nunavut.
Contamination risks threaten ecosystems, wildlife, and food chains despite water monitoring.
Remediation efforts face high costs and data gaps in the Arctic region.
Researchers urge climate models to separately consider lakes and rivers for cleanup planning.
