Researchers have characterized two different types of surface water in the hyperarid salars -- or salt flats -- that contain much of the world's lithium deposits. This new characterization represents a leap forward in understanding how water moves through such basins, and will be key to minimizing the environmental impact on such sensitive, critical habitats.
