I grew up in the Brazilian state of Minas Gerais, a region full of natural resources and, thankfully, aquifers and natural water reservoirs. However, centuries of extraction mismanagement and, more recently, over exploration of mineral resources puts these water resources into jeopardy. (Other problems include mining in open pits and with sludge dams that led to two of the worse environmental disasters in the world in 2015 and 2019, in Mariana and Brumadinho.)
The most interesting part is that Minas Gerais has unusual top-of-the-hill aquifers, instead of in valleys. The rare mineral formation in its mountain tops collects water and only slowly dispenses it to the subsoil, keeping its quality.[0] Needless to say, unfortunately I hold very little hope for it, considering it also sits on some of the most desirable iron ore deposits in the world.
