Item Análisis de la evolución hidrogeoquímica y diagnóstico de procesos de biomineralización controlada en agua subterránea : caso Pozo UPTC, Sogamoso(Universidad Pedagógica y Tecnológica de Colombia, 2018) Díaz Alarcón, Jhonathan Andrés; Alfonso Pérez, Mónica del Pilar; Díaz Lagos, Mercedes; Vergara Gómez, InésGeomicrobiology has special interest in the role played by microorganisms in chemical cycles of chemical elements, including iron. Therefore, the incidence of bacteria in the absorption and reduction of elements of interest has been studied; Experimental studies have also been carried out on the use of catabolic processes of different bacteria as a bioremediation technique during the treatment of groundwater. However, the design of a formulation for the purification of this type of water, it is advisable to know the dynamics of the flow and the great part of the rock-water interaction processes that have influenced the chemical tool of the underground resource. In accordance with the above, it was pointed out the hydrogeochemical processes that have intervened in the evolution of the groundwater captured in the UPTC well, Sogamoso, and the iron and manganese removal capacity in the well water samples was evaluated from the exploitation of bacterial biomineralization processes. To do this, the sampling of eleven (11) samples of groundwater was carried out for the analysis of physicochemical parameters and the determination of the concentrations of the ionic content of interest. The processing of the information was done through hydrogeochemical diagrams (Piper, Stiff and Schoeller-Berkaloff) and some binary graphs that provide information on local conditions; and in a complementary manner, two (2) multivariate statistical methods were applied to quantitatively verify the results obtained through the hydrogeochemical analysis. In a complementary manner, the isotopic content of four (4) of the samples was analyzed to identify the possible recharge zones and, in this way, the preliminary hydrogeological model was constructed for the study area. The integration of this information allowed to define part of the natural and exogenous constituents to the dynamics of the underground flow. Additionally, an experimental method of bioremediation based on the biomineralization mechanisms, typical of the Magnetotactic Bacteria (MTB's) was tested, from which it was possible to eliminate part of the high content of Fe and Mn in the well waters. For this, it was required of the prospection of MTB at regional level, the isolation, the characterization and the verification of the magnetic response of the microorganisms, to finally, perform a process of inoculation of samples enriched with MTB in well water samples. This research for the opening to the future development of methodologies that include the use of microorganisms with magnetic properties and the use of bacterial biomineralization processes for the removal of medical crystals during the treatment of groundwater.
