The case study of the brackish spring of "Almyros of Heraklio" in Crete (Greece) and its vast carbonate coastal aquifer is presented, showing the consequence of preferential flows of continental fresh water and saline sea water in karst galleries in a coastal area. Flow heterogeneity generates unexpected upconing in boreholes, and permits the spring of Almyros not to be directly connected with ...

[1] Submarine groundwater discharge (SGD) into the ocean is increasingly recognized as an important component of land-ocean interaction. Numerous geological settings may be the source of terrestrially derived SGD, including spatially extensive sand dune systems, which are a common coastal setting in tropical, subtropical, and temperate regions throughout the world. Within the catchment of the G...

Coastal aquifers have been extensively studied from the hydrodynamic and geochemical points of view, but there is still a significant gap in knowledge their microbial diversity. The bacterial communities four coastal at different depths salinities were order to infer anthropogenic physico-chemical influences on groundwater microbiota. At level, samples aquifers, with similar salinities, are mor...

Most of the Mediterranean coastal porous aquifers are intensively exploited. Because of climatic and anthropogenic effects, understanding the physical and geological controls on groundwater distribution and flow dynamics in such aquifers is crucial. This study presents the results of a structural investigation of a system located along the coastline of the Gulf of Lions (NW Mediterranean). A ke...

Arsenic species were measured in a bundled-piezometer installed in the Holocene barrier of the Stuarts Point coastal sands aquifer, northern New South Wales, Australia. Vertical distribution shows two peaks of elevated As concentration. At a depth of 10–11 m, concentrations of As, As(V) and As(III) are in the range of 52–85, 38–67 and 14–18 mg/l respectively and the ratio of As(V)/As(III) is we...

[1] We mapped the geometry of a shallow confining layer within the Salinas Valley aquifer system, northern Monterey County, California, using indicator geostatistics. The confining layer was previously interpreted to be mainly Holocene in age, having been deposited as a single unit during post-Wisconsin sea-level rise. We interpret this layer in our field area to be associated with Isotope Stag...
