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 ...
Mobility of Heavy Metals (Pb, Cd, Zn) in the Pampeano and Puelche Aquifers, Argentina: Partition and Retardation Coefficients
(Springer, 2015-07)
The prediction about metals behaviour in soil requires knowledge on their solid-liquid partitioning. Usually it is expressed with an empirical distribution coefficient or Kd, which gives the ratio of the metal concentration ...
Modelo hidrogeológico conceptual del Sistema Acuífero Guaraní (SAG): Una herramienta para la gestión
(2012-07-01)
The Guarani aquifer system (GAS) extends beneath the territories of Argentina, Brazil, Paraguay and Uruguay and thus represents a typical example of a transboundary aquifer. The GAS is an important source of drinking water ...
Doses from Rn-222, Ra-226, and Ra-228 in groundwater from Guarani aquifer, South America
(Elsevier B.V., 2004-01-01)
Groundwater samples were analysed for Rn-222, Ra-226, and Ra-228 in Guarani aquifer spreading around I million kin 2 within four countries in South America, and it was found that their activity concentrations are lognormally ...

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 ...
