Wastewater from nearly 40,000 people and businesses pumped straight into sea as territory still has no treatment plant

Raw sewage from nearly 40,000 people and businesses is being pumped straight into the sea because the British overseas territory of Gibraltar does not have, and has never had, a wastewater treatment plant.

For decades, untreated sewage has poured into the Mediterranean from the southern tip of the peninsula at Europa Point, where the government of Gibraltar says there are “high levels of natural dispersion”.

Prof Kaveh Madani, winner of the Stockholm water prize, was accused of sabotage with his environmental work

Eight years before he got the call telling him he had won the Stockholm water prize, Prof Kaveh Madani was being interrogated by Iran’s Revolutionary Guards, accused of being a spy for the CIA, MI6 or the Mossad.

Today he is in exile and on Wednesday won the world’s most prestigious water prize for combining “groundbreaking research on water management with policy, diplomacy and global outreach, often under personal risk and political complexity”.

Exclusive: Lough Neagh, which supplies drinking water for 40% of NI, contains genes resistant to last-resort antibiotics

Genes capable of creating antibiotic-resistant superbugs have been detected in the UK’s largest lake, which supplies drinking water to about 40% of Northern Ireland.

Testing of water from Lough Neagh, which has a surface area 26 times bigger than Windermere, found genes resistant to a wide range of antibiotics, including carbapenems – drugs reserved for life-threatening infections when all other treatments have failed.

Exclusive: High levels of banned ‘forever chemical’ have been detected in rivers and groundwater at 25 sites

A string of toxic pollution hotspots has been uncovered across Cumbria and Lancashire, with high levels of the banned cancer-causing “forever chemical” Pfos detected in rivers and groundwater at 25 sites.

The contamination, spread across a large area, was uncovered by Watershed Investigations and the Guardian after a freedom of information request revealed high concentrations of Pfos in Environment Agency samples taken in January 2025.

Experts say climate crisis, corruption and lack or misuse of infrastructure among factors driving water conflicts

Water-related violence has almost doubled since 2022 and little is being done to understand and address the trend and prevent new and escalating risks, experts have said.

There were 419 incidents of water-related violence recorded in 2024, up from 235 in 2022, according to the Pacific Institute, a US-based thinktank.

Exclusive: Beijing, Delhi, Los Angeles and Rio de Janeiro among worst affected, with demand close to exceeding supply

Half the world’s 100 largest cities are experiencing high levels of water stress, with 38 of these sitting in regions of “extremely high water stress”, new analysis and mapping has shown.

Water stress means that water withdrawals for public water supply and industry are close to exceeding available supplies, often caused by poor management of water resources exacerbated by climate breakdown.

Exclusive: UCL scientists find large swathes of southern Europe are drying up, with ‘far-reaching’ implications

Vast swathes of Europe’s water reserves are drying up, a new analysis using two decades of satellite data reveals, with freshwater storage shrinking across southern and central Europe, from Spain and Italy to Poland and parts of the UK.

Scientists at University College London (UCL), working with Watershed Investigations and the Guardian, analysed 2002–24 data from satellites, which track changes in Earth’s gravitational field.
