Argentina just ripped up its pioneering glacier law. What does this mean for millions of people’s drinking water?

Javier Milei’s reforms to the law will open up high-altitude areas to mining and risk water reserves already strained by the climate crisis, say activists

S

aul Zeballos was born and raised in Jáchal, a community tucked into the foothills of the Andes in Argentina, drinking water from the river that bears the town’s name. That changed in 2005, when the Veladero gold and silver mine started operating in San Juan province.

A decade later, a major cyanide spill from the mine polluted the rivers in the San Juan region, raising fears it could affect waterways downstream in the Jáchal basin, although further studies have shown that cyanide levels remained at safe levels. Two further spills were reported in 2016 and 2017 and are still under investigation.

Environmentalists and community members such as Zeballos, a 51-year-old accountant turned activist, have long alleged that Veladero, owned by Canada-based Barrick Mining Corporation and China’s Shandong Gold, is operating illegally in an area considered off-limits by Argentina’s Ley de Glaciares – or glacier law.
