The water footprint of lithium extraction technologies: Insights from environmental impact reports in Argentina's salt flats.

This study estimates water consumption in two lithium mines (Olaroz and Fénix) that use different extraction technologies in Argentina's salt flats. Based on Environmental Impact Reports (EIRs), we assess the water footprint (WF) and brine consumption (BC) in both mines. To the best of our knowledge, this study is the first to estimate WF and BC for lithium extraction and provides data to assess water consumption and better understand its implications for local ecosystems and communities.
