Resumen
[ES]En este trabajo se ha llevado a cabo un estudio hidrogeoquímico de los manantiales distribuidos por el municipio de Baeza en la comarca de La Loma de Jaén. La presencia de estos manantiales se debe a la litología del área de estudio, que hace que las areniscas del Mioceno, materiales acuíferos de la zona, capten el agua de lluvia y gracias a los materiales margosos (Mioceno) del muro que actúan como base impermeable, lo cual permite el almacenamiento de aguas en las areniscas. Las numerosas surgencias naturales de agua han sido tradicionalmente aprovechadas para la agricultura y en el pasado, algunas de ellas para consumo humano. La caracterización hidrogeoquímica ha mostrado, que de forma natural estas aguas están altamente mineralizadas, con contenidos importantes de magnesio, calcio, sodio, potasio, sulfatos, cloruros y bicarbonatos. Aparte de las propiedades naturales debidas a la disolución de las rocas del acuífero, la calidad de esta aguas subterráneas presenta un importante deterioro antrópico, con cantidades significativas de nitratos debidos a la agricultura, así como de otros compuestos de enmienda agrícola, como sulfatos, cloruros o potasio.
[EN]A hydrogeochemical study of the springs of Baeza (La Loma, Jaen) has been carried out. The presence of these springs is due to the lithology of the study area, which makes the Miocene sandstones, aquifers in the area, capture rainwater and thanks to the marly wall materials (Miocene) that act as impermeable base, allows storage of water in sandstones. The numerous natural springs of water have been traditionally exploited for agriculture and in the past, some of them for human consumption. The hydrogeochemistry characterization has shown that, naturally, these waters are highly mineralized, with significant contents of magnesium, calcium, sodium, potassium, sulfates, chlorides and bicarbonates. Apart from the natural properties due to the dissolution of rock aquifer, the quality of the groundwater has a significant anthropogenic deterioration, with significant amounts of nitrates due to agriculture, as well as other compounds agricultural amendment, such as sulfates, chlorides or potassium.
