  • Groundwater Resources Recharge Faster than Previously Estimated

    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...

  • Could groundwater drilling solve the drought problems in the Horn of Africa?

    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...

  • Groundwater off Malta could provide potable water for 75 years

    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...

  • Using satellites to track groundwater depletion

    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...

  • Earth’s oldest remaining groundwater aged at 1.2 billion years old

    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...

  • St Kitts and Nevis Minister Addresses The UN-Water Summit On Groundwater At UNESCO

    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...

  • Some groundwater resources near major river deltas could run dry in the next 200 years

    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...

  • IAH at the UN-Water Summit on Groundwater

    IAH’s year ends in Paris in December, with involvement at the UN Groundwater Summit on Groundwater. It is the culmination of the “Groundwater: making the invisible visible” campaign, implemented throughout 2022. This focuses on the SDG 6 Global Acceleration Framework, which is intended to deliver accelerated results that mobilize UN... read more...

  • Islamabad’s recharge wells offer way forward for Pakistan’s groundwater

    In Pakistan, more than 70% of domestic water needs are met by groundwater, a freshwater source literally under our feet. But groundwater resources are often poorly mapped and managed, and are being depleted at alarming and unsustainable rates. Artificial groundwater recharge wells have shown early promise in Pakistan’s capital. Experts... read more...

  • World Toilet Day

    World Toilet Day 2022 gives attention to the impact of the sanitation crisis on groundwater. This observance, held annually since 2013, celebrates toilets and raises awareness of the 3.6 billion people living without access to safely managed sanitation. It is about taking action to tackle the global sanitation crisis and... read more...
