Ongoing research by health organizations has linked the low-level occurrence of natural lithium in drinking water to positive human-health outcomes such as reduced suicide mortality and other mental-health benefits, in addition to potential negative outcomes such as autism and thyroid hormone levels. A new study estimates lithium concentrations in groundwater... read more...

As the atmosphere continues to heat up, more and more heat is penetrating underground. The heat shows up in temperature measurements taken in boreholes around the world. This can be extracted using heat pumps, which are increasing in popularity for space heating across Europe. But warmer groundwater is harmful for... read more...

Planning on the use of water resources in Sardinia has favoured, until now, the creation of artificial basins, yet groundwater can represent a fundamental resource for water supply, especially in regions like Sardinia, where irregularity of rainfall and frequent droughts can put the dam system to the test. This would... read more...

Australia’s northeastern state of Queensland has blocked a carbon capture and storage project proposed by commodities giant Glencore as it could irreversibly harm groundwater used by farmers, the state government said. The pilot project aimed to pump 330,000 metric tons of liquified carbon dioxide into an aquifer 2.3 km (1.4 miles)... read more...

In Brazil, 68% of municipalities collect freshwater for public supply from deep wells, with water levels seen to be receding. Current knowledge about Brazilian waters is based mainly on surface waters — rivers, flood plains, lakes and reservoirs. A new model developed by the Geological Survey of Brazil promises to... read more...

Europe has long been proud of its clean water: accessible, abundant, and drinkable. Most of what we drink, irrigate our crops with, and use in our industries, comes from deep underground, from within vast labyrinths of aquifers. This precious groundwater sustains an entire continent and has helped turn Europe into... read more...

Karst regions, which cover about 15% of the Earth’s land surface, provide freshwater for about a quarter of the world’s population. Despite their importance, these areas are prone to frequent and often unnoticed groundwater flooding. These hidden floods pose significant risks, yet they have historically been neglected by the public,... read more...

Groundwater volumes across Africa are estimated to be equivalent to thousands of years of average total flow of the Nile River. For places like the Horn of Africa, which is blighted by recurrent drought, access to this water could be a game-changer for resilience and water access. Accessing these vast... read more...
