RT Journal Article T1 Origen geológico de los contaminantes (sulfatos) presentes en las aguas subterráneas de la Laguna de Pétrola. (Albacete, España). Resultados preliminares T1 Geological origin of pollutants (sulphate) in the Pétrola Lagoon groundwater (Albacete, Spain). Preliminary results A1 Gómez Alday, Juan José A1 Castaño Fernández, Santiago A1 Sanz Mangas, David AB The salty Lagoon of Petrola, 2 km2 in area, constitutes a representative example of the numerous closed basins that upholster the Iberian southern Subplateau. The lagoon is felt by several saline springs and wells which are placed around it. The brackish nature of its waters drives to the deposition of extensive evaporite deposits during the summer time when the lagoon dries completely. This saline water also imprints to the area a great environmental interest due to aquatic birds that lodge.Dissolved sulphate is one of the most important ions presents in groundwaters. In this study, the first results obtained for determining the sulphur and oxygen source in the groundwater sulphate molecule are presented PB Sociedad Geológica de España YR 2003 FD 2003 LK http://hdl.handle.net/10272/9008 UL http://hdl.handle.net/10272/9008 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
