Aquifers and Groundwater: Challenges and Opportunities in Water Resource Management in Colombia
AI summary Read the abstract
This review examines the state of groundwater resources in Colombia, focusing on contamination threats and sustainable management strategies. While primarily about water management, the study highlights how groundwater -- a key drinking water source -- is increasingly vulnerable to pollutants including microplastics, which could affect the health of communities that rely on these aquifers.
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.

First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
AI summary Read the abstract
This is the first study to investigate microplastic contamination in groundwater in Latin America, examining a coastal aquifer in Northwest Mexico. Researchers found microplastics at all six sampled locations and at multiple depths, confirming that groundwater is not immune to this type of pollution. Since millions of people depend on groundwater for drinking water, these findings raise important questions about microplastic exposure through water supplies.

This review synthesizes current knowledge on microplastic contamination in groundwater, identifying it as a substantially understudied environment compared to surface water and marine systems. The authors describe pathways by which microplastics enter aquifers and discuss management strategies for this largely invisible contamination route.
First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
AI summary Read the abstract
Researchers conducted the first investigation of microplastic pollution in groundwater in Latin America, analyzing six capped boreholes in a coastal aquifer in northwest Mexico for microplastic abundance, concentration, and characteristics. The study detected microplastics in groundwater samples, establishing baseline contamination data for this understudied environmental compartment and raising concerns about drinking water quality in the region.
A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives
AI summary Read the abstract
Scientists reviewed 129 studies and found that tiny pieces of plastic (called microplastics) are contaminating groundwater around the world, which is concerning because groundwater provides drinking water to billions of people. The research shows we don't know enough about this problem, especially in Latin America where only two studies have actually tested groundwater for plastic contamination. This matters because we need better monitoring and policies to protect our underground water sources from plastic pollution that could affect human health.
