Abstract: The high concentrations of fluorides and arsenic found in exploited groundwater are an increasing global problem. This problem is accentuated principally in arid and semi-arid regions which depend primarily on groundwater extraction to supply the demand of drinking water for their communities, as is the case of Aguascalientes City, Mexico. The present work gathers and synthesizes the studies and research papers that have been done to determine the fluoride and arsenic concentrations in the groundwater of the Aguascalientes Valley aquifer, as well as those that enumerate the risks to which the communities that use this water are exposed, with the objective of underlining the importance of continuing this type of research to deepen the knowledge and understanding of the system and the presence of these elements in groundwater, as well as to develop solution strategies to tackle the problem. After an extensive revision of the bibliography, the problem is contextualized into a regional panorama and placed within the national and global outlooks, permitting in this way to give the foundations for future water quality studies in the region.
