DescriptionMining is one of the most important sources of income for the Baja California Sur state. This state is the second most important area for mineral (gold, silver, copper) and non-mineral (salt) mining activities in the Mexican Republic. In the San Antonio-El Triunfo region, mineral-mining activities flourished during the 19th century. Tons of debris containing a high quantity of arsenic were deposited on the soil as a by-product of these activities. In 1998, local inhabitants reported their suspicion of the contamination of the region's wells. For this reason, we developed this study, which establishes the sampling of underground water in the region. Our results indicate that all the underground water sampled in the region's wells exceeded official safe limits (0.05 mg/l).
