Thawing Permafrost Turns Alaska's Rivers Orange With Toxic Metal Levels
0
·2 viewsRivers across Alaska are turning orange as thawing permafrost triggers natural acid rock drainage, releasing metals and sulfates into waterways. Researchers studied six watersheds in the Brooks Range to evaluate changes in water color and chemistry over recent years. The acidic runoff carries metal concentrations comparable to or exceeding those found near mine waste sites. Downstream ecosystems and local communities are being affected by the deteriorating water quality. Scientists are continuing to monitor the rivers to better understand the long-term environmental consequences of climate change.
