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...

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...
