New research sheds light on the connection between groundwater and surface water fluxes. The findings show a higher-than-estimated percentage of groundwater returning to the surface via river flow or when used by vegetation. The higher recharge rates suggest that natural phenomena, such as evapotranspiration and streamflow, depend on groundwater much... read more...

Climate change continues to make it mark in Africa, disrupting weather patterns and in some cases, making them more extreme. The Horn of Africa is facing the threat of a fifth consecutive failed rainy season – and that’s brought with it frequent devastating droughts. But a solution could be much... read more...

Scientists believe that offshore freshened groundwater below the seafloor off the Maltese islands could provide potable water for 75 years. Offshore freshened groundwater is groundwater with salinity below that of seawater that is stored in sediments and rocks below the seafloor. However, most of this groundwater appears to be hosted... read more...

A major cause of land subsidence is the removal or disturbance of groundwater in soil and between rocks and sand found underground. Because subsidence often makes areas uninhabitable, these conditions can cause water and food insecurity, and potential political issues. To help investigate solutions, researchers are using satellite radar altimetry with... read more...

Dear Colleagues, Happy new year! At the United Nations Groundwater Summit in Paris this December, IAH members from all over the world brought pictures, stories, and actual groundwater samples from their home countries. The groundwater was mixed together symbolically, to demonstrate that groundwater can unite people, and that it is... read more...

An international team of researchers have discovered 1.2-billion-year-old groundwater 2.9 km below the earth’s surface in a gold- and uranium-producing mine in Moab Khotsong, South Africa, shedding more light on how life is sustained below the Earth’s surface and how it may thrive on other planets. The researchers found large... read more...

The Hon. Konris Maynard of St. Kitts and Nevis addressed the UN-Water Summit on Groundwater held at UNESCO, Paris. He spoke of the chronic paucity of groundwater supplies in St. Kitts and Nevis and across the entire Caribbean, a situation that has intensified as a result of climate change. St. Kitts... read more...

From the Mississippi to the Niger, river deltas have long drawn people and industry, both with a seemingly unquenchable thirst for fresh water. Much of that water is drawn from underground aquifers deep beneath the sprawling delta systems. But for how much longer? Using computer models to assess these groundwater... read more...
