“…Climate change has effects on groundwater recharge [38], and in Colombia, it has been seen how climate phenomena have had effects on the state of wetlands and groundwater [21,36]. To know the true state of groundwater and the maintenance of eco- Most of the studies on groundwater in Colombia focus on water management, its usage, and its quality, particularly in regions of demographic, agricultural, and industrial importance [41,[44][45][46][47]. These studies reveal the degradation of water quality [43,46,[48][49][50][51], the depletion of water resources in arid and impoverished areas [44], and the utilization and management of these waters [44,45,48,52].…”

Water is essential for life on Earth, playing fundamental roles in climate regulation, ecosystem maintenance, and domestic, agricultural, and industrial processes. A total of 70% of the planet is covered by water. However, only 2.5% is fresh water, and much of it is inaccessible. Groundwater is the main source of the planet’s available water resources. For that reason, groundwater is a critically important resource, and is increasingly vulnerable due to the climate crisis and contamination. These challenges threaten the availability of clean and safe water, necessitating an understanding of effective and sustainable management. This review presents an overview of the concepts of aquifers and groundwater. Also, it reflects on the importance of these resources in developing countries such as Colombia (South America). In addition, it considers the characteristics of mineral waters, their uses, and associated risks, as well as their exploration and control policies. Colombia is a country with immense water and biological wealth and is crucial to maintaining the climate and availability of global water resources. Nevertheless, managing Colombia’s aquifers is a challenge, as many have not yet been fully explored. In order to achieve this, it is necessary to study hydrogeochemistry through the application of advanced technologies to analyze the dynamics, distribution, and quality of groundwater, as well as its vulnerability to pollution and climate change. On the other hand, the consumption of mineral groundwater can have health benefits, such as positive cardiovascular and gastrointestinal effects. But geogenic, biogenic, or anthropogenic elements such as heavy metals and microplastics can pose a risk to human health. The need for proper management of water resources to prevent risks to human health and the environment is emphasized. Therefore, an integrated approach to water resource management will ensure conservation and sustainable use, secure a continuous supply of freshwater, and facilitate adaptation to climate change.

“…In free flow aquifers, this potential is higher due to the rapid recharge of the geological unit (IRITANI; EZAKI, 2009). Vulnerability indicates the potential for contamination of groundwater resources according to natural and manmade activities (AL HALLAQ; ELAISH, 2012;BETANCUR et al, 2013;DUCCI;SELLERINO, 2013;EDET, 2014).…”

Assessment of groundwater contamination potential using geological, hydrological and hydrogeological attributes, is an efficient mechanism of sub-surface water resources protection and conservation. However, usually this method does not take into consideration the potentially polluting human activities, either in punctual or diffuse sources, or because the relative importance of the attributes are not considered. The paper proposes a multi-criteria approach as a way of solving this gap, reducing subjectivity and considering land use/cover due human actions influence in the process. The study was developed in Araras river watershed (Paraná Basin, Brazil) using rock, groundwater, relief, soils, and land use/land cover classification, employing multi-criteria analysis and data of contamination sources. The potential contamination classification showed the predominance (54% of the area) of very high and high potential, especially due to geological environment conditions (exploitation areas and groundwater recharge of the Itararé Aquifer -clastic sedimentary and free flow). The contaminant sources analyzed are located mainly in higher potential contamination areas. Keywords:Groundwater; Water quality; Water contamination; Multi-criteria analysis. RESUMOA avaliação do potencial de contaminação da água subterrânea a partir dos atributos geológicos, hidrológicos e hidrogeológicos, é reconhecida como um mecanismo eficiente de proteção e conservação dos recursos hídricos de subsuperfície. No entanto, tal método por vezes apresenta como deficiências a desconsideração das atividades humanas que são potencialmente contaminantes, seja na forma de fontes pontuais ou difusas, ou por não considerar a importância relativa dos atributos na análise. Visando contribuir para a solução dessa lacuna, o presente trabalho se valeu de análise multicritério como forma de reduzir a subjetividade dessa análise e de informações de uso e cobertura do solo e de fontes de contaminação para tratar os efeitos da ação humana no processo. O trabalho foi desenvolvido na Bacia Hidrográfica do rio das Araras (Bacia do Paraná, Brasil) a partir do tratamento dos dados de substrato rochoso, hidrografia, relevo, solos, classificação de uso e cobertura do solo usando análise multicritério e dados de fontes de contaminação. A classificação do potencial de contaminação mostrou a predominância (54% da área) de áreas classificadas como potencial muito alto e alto, especialmente em função do ambiente geológico (áreas de explotação e recarga do Aquífero Itararé, sedimentar clástico e livre). As fontes contaminantes analisadas se localizam principalmente nessas áreas com maiores potenciais de contaminação.
