The Earth holds approximately 20 million cubic kilometres of groundwater, roughly equal to the amount of saline water below the surface. But not all of it is usable: some lies too deep to extract, while other portions are already being tapped faster than they can recharge. Groundwater supplies half the... read more...

Entire villages along Indonesia’s northern coast are being swallowed by the sea. Semonet in Central Java is one of the clearest examples. Once a thriving fishing community, it’s now completely deserted. Multiple factors are at play: geological and man-made, like groundwater extraction for domestic and industrial use. Climate change, intense... read more...

A major scientific discovery beneath Greece’s seafloor has revealed vast reserves of freshwater stored deep underground. These freshwater reserves stretch from about 20 metres (66 feet) to as deep as 700 metres (2,297 feet) below the seafloor. The discovery sheds new light on how ancient groundwater systems formed — and... read more...

As Pakistan undergoes a solar revolution, farmers are increasingly ditching diesel and grid power for sun-powered tube wells. The solar boom has coincided with the depletion of water tables in Pakistan’s most populous province, according to previously unreported Punjab water authority documents viewed by Reuters. The documents did not pinpoint any... read more...

This World Bank report details the rationale and methodological steps taken to assemble a global dataset of aquifer typologies and resource availability. Such a global dataset can be used to answer high-level but fundamental questions related to the economic accessibility or potential of groundwater in a region and the implications... read more...

An abandoned coal exploration borehole in Queensland was discovered emitting methane and forcing groundwater into the air like a geyser. Many abandoned boreholes may be emitting methane and the rate of leakage could be influenced by the geology beneath and by the state of water extraction in other areas, causing... read more...
