Water Stewardship
Our priority is to sustainably manage water resources by limiting its use and safeguarding its quality. We engage with our neighboring communities to collaboratively manage shared water resources throughout the project life cycle. From the outset, we have incorporated water stewardship considerations into our project decisions and design – a reflection of our driving focus on using water efficiently and limiting water quality impacts.
Both Caucharí-Olaroz in the Jujuy region of Argentina and Thacker Pass in northern Nevada are considered low-medium for overall water risk, whereas Pastos Grandes is considered low, according to the Water Risk Atlas
Thacker Pass
In designing and developing Thacker Pass, Lithium Americas will leverage available filtration, evaporation and centrifugation technology, to maximize the reuse and recycling of processed water, limiting the amount of water obtained from natural sources. Based on a detailed water cycle assessment, any water withdrawn for the project is expected to be recycled and reused an average of 7 times within the production process.
Thacker Pass is being designed as a Zero Liquid Discharge facility, intended to prevent the discharge of industrial wastewater into the environment. This is an extensive commitment because it means all water that is filtered from tailings must be evaporated or recycled for reuse within the site’s production process.
To minimize the cumulative impact of water withdrawal on the local aquifer, Thacker Pass will use existing water rights so that the overall withdrawal volume is consistent with past years. Additionally, when water rights were transferred from agricultural use to industrial use in 2021, nearly a quarter (22.5%) of the total allowable withdrawal volume was returned to the state of Nevada. No additional water rights are required for Phase 1.
In February 2022, Thacker Pass received the State of Nevada Water Pollution Control Permit, which officially authorizes the construction, operation and closure of the mine in accordance with limitations/conditions set forth in the permit.
We will also develop compliance management and reporting systems that monitor water withdrawal and consumption in advance of construction to support compliant operations.
