dc.description.abstractIn the world, approximately two billion people live under water stress. In Latin America and the Caribbean, water quality is often poor due to the presence of natural or anthropogenic contaminants. Emerging pollutants (ECs) can negatively affect the environment or human health. In Chile, the soils of the Atacama Desert are the most extensive natural perchlorate reservoirs in the world, directly impacting the composition of drinking water sources in northern Chile. This study addresses the problem of two oxyanions, specifically perchlorate and chlorate, in the drinking water of northern Chilean cities, in the Atacama Desert area. The use of organic salts as an intermediate for perchlorate desorption and regeneration of a highly selective resin for perchlorate was studied. The findings of perchlorate bioreduction in organic salts brines are promising even without adding external carbon sources and electron donors. This study highlights the need to establish systematic monitoring, regulation, and treatment of these ECs in drinking water sources. This study opens the possibility of continuing to investigate the use of organic salts to recove compounds of interest, while extending the useful life of materials such as ion exchange resins.
