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 ...
Arsenic and associated trace-elements in groundwater from the Chaco-Pampean plain, Argentina: Results from 100 years of research
(Elsevier Science, 2012-05)
The Chaco-Pampean plain, Argentina, is a vast geographical unit (1,000,000 km2) affected by high arsenic (As) concentrations in universal oxidizing groundwater. The socio-economic development of the region is restricted ...
Shallow geophysical evaluation of the transition zone between the Guaraní and Yrendá-Toba-Tarijeño aquifer systems (Argentine Gran Chaco)
(Universidad Nacional Autónoma de México. Centro de Geociencias, 2014-03)
The shallow geology and local hydrogeological systems of the Argentine Gran Chaco are poorly known. This area is part of the Chaco-Pampean Plain in the Andean foreland and is predominantly known by the subsurface data. ...
Groundwater arsenic in the Chaco-Pampean Plain, Argentina: Case study from Robles county, Santiago del Estero Province
(Pergamon-Elsevier Science Ltd, 2004-02)
In large parts of rural Argentina people depend on groundwater whose As content exceeds the Argentine drinking water standards (0.05 mg l 1). The most affected areas are located in the Chaco-Pampean Plain, where aquifers ...
The role of loess weathering in the groundwater chemistry of the Chaco-Pampean Plain (Argentina)
(Elsevier, 2020-08)
The Chaco-Pampean Plain (CPP), Argentina, is one of the most extensive loess areas in the world, higlhly productive in terms of agriculture and livestock and with a generalized groundwater signature of Na-HCO3 water type. ...
Shallow geophysical evaluation of the transition zone between the Guaraní and Yrendá-Toba-Tarijeño aquifer systems (Argentine Gran Chaco)
(Universidad Nacional Autónoma de México, 2013-12)
The shallow geology and local hydrogeological systems of the Argentine Gran Chaco are poorly known. This area is part of the ChacoPampean Plain in the Andean foreland and is predominantly known by the subsurface data. ...
Geological-geomorphological and geochemical control on low arsenic concentration in the Lerma valley groundwater between the two high arsenic geologic provinces of Chaco-Pampean plain and Puna
(Science of the Total Environment, 2019-09)
Argentina is known for having one of the most extensive areas with high arsenic (As) concentration in groundwater in the world. These areas correspond to two main geological provinces, the Puna plateau and the Chaco-Pampean ...
Key hydrological processes in the Del Azul Creek basin, sub-humid Pampean Plain
(Elsevier, 2021-02)
Groundwater plays an important role in the economic development of the Chaco-Pampean Plain (Argentina), where industry, agriculture and cattle farming are the main economic activities. The 66% of the country's population ...
Assessment of processes controlling the regional distribution of fluoride and arsenic in groundwater of the Pampeano Aquifer in the Del Azul Creek basin (Argentina)
(Elsevier Science, 2016-10)
Groundwater in the upper 50 m of the Pampeano Aquifer in the Del Azul Creek basin (Argentina) has F and As contents above the WHO safe drinking levels. This basin is situated to the SE of the Chaco-Pampean plain, in Buenos ...
Arsenic in porewaters of the unsaturated zone of an Argentinean watershed: Adsorption and competition with carbonate as important processes that regulate its concentration
(Springer, 2015-06)
The arsenic (As) concentration in porewaters of the unsaturated (vadose) zone of a watershed located in the Chaco-Pampean Plain of Argentina was investigated. A water displacement method using carbon tetrachloride was ...
