Origen geológico de los contaminantes (sulfatos) presentes en las aguas subterráneas de la Laguna de Pétrola. (Albacete, España). Resultados preliminares

Abstract

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
