with a maximum area of 0.17 km2, is a shallow basin (up to 0.5 m deep) fed by groundwater [26]. In addition, low water inputs were derived from a small,extremely ephemeral stream. Caballo Alba presents high pH values ranging from 9.0 to 10.4, thus presenting brackish-to-saline water (1–16 g·L−1), high carbonate concentrations, with chloride dominant over sulfate.
