Analysis of the geological control on the spatial distribution of potentially t...
Giménez-Forcada, Elena; Luque-Espinar, J. A.; López-Bahut, T.; Grima-Olmedo, Juan; Jiménez-Sánchez, Jorge; Ontiveros-Beltranena, Carlos; Elster, DanielABSTRACT: The distribution of the high concentrations of arsenic (As) and fluoride (F-) in groundwater on a Pan-European scale could be explained by the geological European context (lithology and structural faults). To test this hypothesis, seventeen countries and eighteen geological survey organizations (GSOs) have participated in the dataset. The methodology has used the HydroGeoToxicity (HGT) and the Baselin...
Assessment of chloride natural background levels by applying statistical approa...
Pulido-Velazquez, D.; Baena-Ruiz, L.; Fernandes, Judite; Arnó, Georgina; Hinsby, Klaus; Voutchkova, D. D.; Hansen, B.; Retike, I.; Bikse, J.ABSTRACT: Estimated natural background levels (NBLs) are needed to assess groundwater chemical status according to the EU Groundwater Directive. They are commonly derived for different substances by applying statistical methodologies. Due to the complexity of the sea water intrusion process, some of those methods do not always provide appropriate assessment of chloride NBLs. This paper analyzes the applicabilit...
