Across northern Alaska, dozens of pristine waterways are undergoing a shocking transformation. Crystal clear streams are turning a bright, milky orange color that is easily visible from airplanes and satellites.
Scientists studying the Brooks Range discovered that over seventy rivers and creeks have drastically changed color since 2018. The water has become intensely acidic, tasting sour and corroding sampling equipment within minutes.
Researchers found that rapidly thawing permafrost is the root cause. As frozen ground melts, ancient minerals containing iron and toxic heavy metals like zinc, nickel, and cadmium oxidize upon contact with air and water. This reaction forms iron oxide rust that smothers riverbeds.
The acidic, rusted runoff destroys native fish habitats, threatening species like Dolly Varden and chum salmon. It also imperils the drinking water supplies of nearby Indigenous communities who rely on these pristine waterways.
