Urban aquifers are a potential alternative, with which to cover the rising demand for freshwater. However, they are commonly polluted by a wide range of anthropogenic substances, including rare earth elements (REEs). In this context, it is essential to investigate the presence and behaviour of these pollutants, in order to safely use urban groundwater. An example of these contaminants is Gadolinium, which can reach the environ...

In the current context of population growth and climate change, it is essential to effectively manage groundwater resources, to improve their quality, and to determine the behaviour of certain contaminants. Groundwater quality can be worsened most often by anthropogenic factors but can also be altered by natural factors depending on the chemical signatures of water sources (i.e., hydrochemical reactions) as a result of mixing...
