“…This group includes pesticides, veterinary products, food additives, nanomaterials, industrial compounds, halogenated solvents, personal care products, and pharmaceutical residues. Recently, attention has been focused on the detection of the latter due to their high persistence in the environment [86]. Many of these compounds may not have direct toxic effects on living organisms, but they can reduce the levels of dissolved oxygen in groundwater.…”

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.

“…However, it can sometimes be extremely difficult to assign certain compounds to a particular group, as they may belong to more than one category. The presence of organic contaminants in groundwater is poorly characterized, and understanding their temporal and spatial variation remains a priority [86].…”

“…Investigating its spatial distribution is essential for delineating hydrogeochemical processes and flow paths in mines. Currently, a suite of established methodologies, including ion ratios, multivariate statistical analysis, isotopic tracing, hydrochemical modeling, geographic information systems (GIS), hierarchical clustering analysis (HCA), principal component analysis (PCA), and self-organizing maps (SOM), are extensively utilized to investigate the dominant factors and spatiotemporal variations of hydrochemical evolution within the multilayered aquifer systems [8][9][10][11][12][13][14][15][16][17][18][19]. Moreover, water-stable isotopes and tritium radioactive isotopes have been extensively employed to investigate the origin and age of the water [20][21][22][23][24].…”

Taiyuan Formation limestone groundwater is the main aquifer threatening the safety of exploration under deep mining in the Huaibei coalfield. Therefore, acknowledging the hydrochemical characteristics and constructing reverse hydrogeochemical modeling are crucial for predicting and preventing mine water hazards. In this study, the mathematical statistical analysis, Piper threeline diagram, Gibbs diagram, ion proportional relationship, Chlorine-Alkali index, and the reverse hydrogeochemical modeling were employed for determining the hydrochemical characteristics and the formation mechanism. The results revealed that the hydrochemical types of groundwater samples were SO 4 .Cl-Ca.Mg and HCO 3 .Cl-Na, respectively. The water-rock interactions were primarily influenced by the leaching and the cation exchange, with these processes being more intense in the eastern region. Through reverse hydrogeochemical modeling, the water-rock interactions in the process of groundwater runoff were quantitatively verified, viz. the calcite and the dolomite were saturated and precipitating, while the gypsum and the halite were unsaturated and still dissolving. Furthermore, the simulations of mass transfer in groundwater runoff indicated that the dissolution and the leaching of gypsum, dolomite and halite, positive ion exchange, the precipitation of calcite, and the dissolution of CO 2 gas predominantly occurred along four simulated flow paths. These results offered a scientific foundation for the prevention and controlling of mine water hazards in deep mining contexts.
