Hydrogeochemical and isotopic indicators of vulnerability and sustainability in the GAS aquifer, São Paulo State, Brazil
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. ...
Simposio: Contamination and restauration of aquifers
(Universidad Autónoma del Estado de México, 2014)
Fluoride in the groundwater of the Tubarao and Crystaline aquifers, Salto-Indaiatuba region (SP)
(ESCOLA DE MINAS, 2010)
Anomalous concentrations of fluoride in groundwater were identified in 19 drilling wells in the Salto-Indaiatuba region, Sao Paulo State, with an average concentration of 3.03 mg dm(-3) and a maximum of 6.95 mg dm(-3), ...
Assessing the impact of recycled water quality and clogging on infiltration rates at a pioneering Soil Aquifer Treatment (SAT) site in Alice Springs, Northern Territory (NT), Australia
Infiltration techniques for managed aquifer recharge (MAR), such as soil aquifer treatment (SAT) can facilitate low-cost water recycling and supplement groundwater resources. However there are still challenges in sustaining ...
Stable isotope hydrology in fractured and detritic aquifers at both sides of the South Atlantic Ocean: Mar del Plata (Argentina) and the Rawsonville and Sandspruit river catchment areas (South Africa)
(Pergamon-Elsevier Science Ltd, 2017-01)
The aim of this work is to characterize the isotope composition of water (2H and 18O) in order to establish the relationship between fractured and detritic aquifers in similar hydrological environments located at both sides ...
GIS Applied to the Mapping of Land Use, Land Cover and Vulnerability in the Outcrop Zone of the Guarani Aquifer System
(Elsevier B.V., 2015-01-01)
This study presents the vulnerability mapping of Guarani Aquifer System (GAS) in the municipality of Ribeirao Bonito, the central region of the state of Sao Paulo, through the application of Pesticide DRASTIC index assigned ...
Analytic element modelling for strip aquifers
The Analytic Element Method (AEM) provides a convenient tool for groundwater flow analysis in unbounded continuous domains. The AEM is based on the superposition of analytic functions, known as elements, useful at both ...
Water-Rock Interactions in the Bauru Aquifer System - Sao Paulo State, Brazil
(Elsevier B.V., 2017-01-01)
The study focuses on the assessment of mineral saturation indexes using data of physicochemical analysis of groundwater samples from different units of the Bauru Aquifer System, in the State of Sao Paulo, Brazil. The ...
Radon in groundwaters from Guarany aquifer, South America: environmental and exploration implications
(Elsevier B.V., 2002-12-01)
Groundwater and sandstone samples were analyzed for radon in Guarany aquifer, Parana sedimentary basin, South America. The dissolved radon ranged between 3 and 3303 pCi/l, being lognormally distributed, with a modal value ...
