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 ...
DC resistivity investigation in a fractured aquifer system contaminated by leachate from an old dump
(Inst Geophysics Unam, 2017-10-01)
The dumps are areas of final disposal of solid wastes directly into the soil, with no technical criteria or collecting systems of gases or liquids. A large part of Brazilian municipalities have used this extreme damaging ...

A comparative study of aquifer systems occurring at the Paraná sedimentary basin, Brazil: U-isotopes contribution
(2013-01-01)
The radioactivity due to 238U and 234U in three aquifer systems occurring within the Paraná sedimentary basin, South America, has been investigated. Uranium is much less dissolved from fractured igneous rocks than from the ...
Modeling rock-water interaction of fractured aquifer in itabuna/BA regionModelagem da Interação Água/Rocha nos Aquíferos Fraturados da Região de Itabuna/BA
(2019-01-01)
This research aimed to investigate the geochemical mechanisms that govern the strong hydrochemical variations in the fractured aquifers of the Itabuna/BA region. Plagioclase and quartz comprise the major mineralogy of ...
Derivative analysis of pumping tests carried out in fractured aquifers in the Jundiaí Municipality - state of São Paulo, BrazilAnálise derivativa de testes de bombeamento em aquíferos fissurais no município de Jundiaí/SP
(2019-01-01)
Groundwater extracted from crystalline aquifers is the main water supply in many parts of the world, particularly in developing regions such as Sub-Saharan Africa, Brazil and India. Decades of research have revealed the ...
Uranium series disequilibria in ground waters from a fractured bedrock aquifer (Morungaba Granitoids-Southern Brazil): Implications to the hydrochemical behavior of dissolved U and Ra
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Activity concentrations of dissolved U-234, U-238, Ra-226 and Ra-228 were determined in ground waters fromtwo deep wells drilled in Morungaba Granitoids (Southern Brazil). Sampling was done monthly for little longer than ...
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), ...
