Hydrogeochemical and isotopic indicators of vulnerability and sustainability in the GAS aquifer, São Paulo State, Brazil
(2017-12-01)
Study region The Guarani Aquifer System (GAS), São Paulo State, Brazil, an important freshwater resource regionally and part of a giant, transboundary system. Study focus Groundwaters have been sampled along a transect. ...
Geochemical evolution, residence times and recharge conditions of the multilayered Tubarão aquifer system (State of São Paulo–Brazil) as indicated by hydrochemical, stable isotope and 14C data
(2020-01-01)
The Tubarão aquifer system constitutes a very complex, multilayered aquifer enclosed in the Paraná basin (central-southern part of Brazil). Despite the relatively low productivity of wells, groundwater represents an important ...
Anthropic-induced salinization in a dolomite coastal aquifer. Hydrogeochemical processes
(Elsevier, 2020)
The dolomite coastal aquifer of Balanegra (SE Spain) is the only source of irrigation water in an area of flourishing intensive agriculture. This scenario has consequently led to a severe exploitation of the water resources. ...
Control of the mobilization of arsenic and other natural pollutants in groundwater by calcium carbonate concretions in the Pampean Aquifer, southeast of the Buenos Aires province, Argentina
(Elsevier, 2019-07)
The water supply for human consumption in the Chaco-Pampean region in Argentina is restricted by the low quality of groundwater due to elevated concentrations of arsenic and other trace elements. Previous studies indicated ...
Stable isotopes, carbon-14 and hydrochemical composition from a basaltic aquifer in São Paulo State, Brazil
(2017-02-01)
The Cretaceous Serra Geral Aquifer (SGA) is contained within one of the largest continental flood basalts in the world, reaching a thickness up to 1700 m in the center of the Paraná Basin. The SGA is one of the most important ...
Hydrogeochemistry characterization from Adamtina Aquifer in the urban area of Bauru, SPCaracterização hidrogeoquímica do Aquífero Adamantina na área urbana de Bauru, SP
(2014-07-01)
This work characterized the groundwater from Adamantina Aquifer in the urban area of Bauru, São Paulo State. Twenty four sampling points were established in the Adamantina Aquifer, Bauru Aquifer System, analyzing the ...
Identifying and quantifying geochemical and mixing processes in the Matanza-Riachuelo Aquifer System, Argentina
(Elsevier, 2017-12)
The Matanza-Riachuelo River Basin, in the Northeast of the Buenos Aires Province, is one of the most industrialized and populated region in Argentina and it is worldwide known for its alarming environmental degradation. ...
Multi-isotope (δ 2H, δ 18O, δ 13C-TDIC, δ 18O-TDIC, 87Sr/86Sr) and hydrochemical study on fractured-karstic and detritic shallow aquifers in the Pampean region, Argentina
(Taylor & Francis Ltd, 2020-09)
Fluxes between fractured-karstified and detritic aquifers are commonly poorly understood in many environments. These two types of aquifers are in contact in the southeastern Pampean region in the Argentine Buenos Aires ...
