Water from beneath the ground supplies 30 per cent of Australia’s water needs, providing a lifeline for communities, industries and environment. To ensure groundwater is used sustainably, scientists are using ground-breaking technologies to measure how much rain is making it into underground aquifers.

UNESCO and the Minister of Water Resources and Meteorology met to discuss their respective water mandates and initiatives and explore collaboration opportunities. Two key groundwater projects currently being implemented by UNESCO and its partners aim to address data, knowledge and capacity gaps in transboundary groundwater governance and management and strengthen... read more...

Coal seam gas (CSG) is extracted by pumping out groundwater, which lowers underground pressure, can lead to shrinking of geological layers and make the ground above sink over time. A new model shows how coal seam gas extraction causes land to sink by linking groundwater loss and coal shrinkage, helping... read more...

A recent study shows how ancient groundwater beneath the ocean floor may have interacted with ice sheets and rising sea levels during past climate changes. Fossil groundwater may have been influenced by dramatic changes in sea level and the movement of massive ice bodies. Although previous studies suggest that deep... read more...

Groundwater and not glacier melts sustain the Ganga during the hot summer months in India, according to the first ever comprehensive isotope study done by the Indian Institute of Technology-Roorkee (IIT-Roorkee). The study found that that the Ganga is not drying because of groundwater depletion but because of over-extraction, excessive... read more...

Karst groundwaters are vital resources, providing drinking water to nearly 10% of the world’s population. However, human activities and global change have deteriorated the karst water quality and dependent ecosystems. This article looks at how scientists model contaminant transport, and future research directions.

As the planet gets hotter and its reservoirs shrink and its glaciers melt, people have increasingly drilled into a largely ungoverned, invisible cache of fresh water: the vast, hidden pools found deep underground. A new study finds that the landmasses of the planet are drying. In most places there is... read more...

According to a recent UN-Habitat report, Kabul is facing an unprecedented water crisis. Groundwater levels have dropped significantly, putting more than 6 million residents of Kabul at serious risk. The report warned that local efforts alone won’t be enough to halt the downward spiral. Find out more https://english.news.cn/asiapacific/20250724/8971f131889046828560041ef2b46ca4/c.html read more...

Climate change is causing sea levels in the North Sea to rise. This poses a challenge for islands like Norderney at the German North-Sea coast, which have their own fresh water supply in the sandy subsoil. A “Freshwater Lens Walk” aims to bring the island’s freshwater lens to life –... read more...

Researchers modelled groundwater temperature trends from 2000 to 2100. They estimated that groundwater could warm by up to 3.5°C over the next 100 years. Find out more https://sciworthy.com/is-groundwater-heating-up/ read more...
