Recharge área maps from precipitation isoscapes. Case study: Aburrá Valley, Colombia

BOLETÍN GEOLÓGICO Y MINERO (2021)

The environmental isotopes are a tool for interpreting the hydrological processes related to underground environments. These are used for the validation of hydrogeological models, in terms of recharge, transit and discharge zones, as well as the identification of groundwater interactions with other water bodies and groundwater residence time in the hydrogeological units. The determination of the recharge processes have usually been validated from knowledge about the stable isotopes present in the water molecule (18O and 2H). At the regional level, this evaluation has been addressed through the construction of isoscapes combined with an understanding of the hydrological characteristics present in the study area and knowledge of conceptual hydrogeological models. The objective of this study is to apply a scheme for the analysis of potential groundwater recharge zones, from 18O and 2H spatial variability in precipitation, baseflow and groundwater, using spatial modelling tools. Based on a preliminary work done for the Antioquia department, a strategic area was chosen in which the results are more forceful and have greater implications in groundwater management: the Aburrá Valley-Colombia.

A multi-tracer approach for understanding the functioning of heterogeneous phreatic coastal aquifers in humid tropical zones

Hydrological Sciences Journal (2021)

Ana Karina Campillo Jean‐Denis Taupin Teresita Betancur Nicolas Patris Virginie Vergnaud

In many areas around the world, phreatic coastal aquifers are vulnerable to contamination and saltwater intrusion. This study aims to explore the hydrodynamic functioning of the coastal phreatic aquifer of the Urabá region, Colombia, based on the identification of hydrogeochemical processes and groundwater residence and transit times. Hydrodynamic data showed a fast response of the piezometric levels to precipitation with a maximum time lag of 48 h. Mean annual recharge was estimated at 19% with respect to precipitation. Another recharge mode is linked to infiltration from surface water, according to the hydrodynamic results. The main geochemical process identified is hydrolysis due to dissolved carbon dioxide, inducing silicate weathering and resulting in predominant HCO3-Ca-Mg facies. Monitoring of δ18O and δ2H compositions combined with 3H, 14C, chlorofluorocarbons (CFCs) and SF6 contents showed a fast recharge in the aquifer. Groundwater dating indicates recent waters mixed with older (>40 years) waters.
