United Utilities refuses to hand over data on sewage discharges into Windermere

Water company claims information is not in the public interest despite widespread pollution of UK waters

‘It’s a national disgrace’: fury at sewage-filled Windermere over toxic algae and dead fish

One of the UK’s biggest water companies is fighting a legal battle to block public access to data on treated sewage it is discharging into Windermere in the Lake District.

United Utilities initially claimed that data from phosphorus monitors at sewage treatment works at the lake “was not environmental information”. It later claimed the information on phosphorus – which can pollute watercourses when at high levels – was “internal communication” and exempt from disclosure.

Global plastic production must be cut to curb pollution, study says

Analysis lays bare huge challenge of mismanaged waste on eve of UN plastic treaty talks in Busan

Global plastic production must be reduced to tackle the immense challenge of plastic pollution, according to an analysis published on the eve of crucial talks to hammer out the world’s first legally binding treaty on plastic waste.

Mismanaged plastic waste, which leaches into the environment and can be harmful to health, will double to 121m tonnes by 2050 if limits are not placed on the production of plastic, according to Samuel Pottinger, the lead author of the research.

NSW regulator chose to reveal content of Sydney’s mystery beach balls on day of US election

After debris balls were widely reported to be tar, testing coordinated with EPA revealed they were consistent with human-generated waste, or ‘likely lumps of fatberg’

The NSW environment watchdog allegedly knew for more than a week that thousands of mystery balls that washed up on Sydney beaches last month were probably consistent with human-generated waste before it made the news public as US election results dominated headlines.

A statement from the Environment Protection Authority (EPA) on Wednesday revealed the balls comprised fatty acids, petroleum hydrocarbons and other organic and inorganic materials – including traces of drugs, hair, motor oil, food waste, animal matter and human faeces.

‘The first thing I did was poke it’: Canada beach blobs mystery solved by chemists

Newfoundland Memorial Univeristy team find white masses are likely material used to clean pipes in oil industry

When the chemist Chris Kozak finally got his hands on a sample of the mysterious blobs that recently washed up on the shores of Newfoundland’s beaches, Project Unknown Glob officially began.

At his disposal, Kozak and a team of graduate students had the “gorgeous” new science building and “world-class facilities” of Newfoundland’s Memorial University to run a battery of tests on the white, doughy blob.

Paris drivers warned of fines as city begins limiting traffic in parts of centre

Three-month ‘educational phase’ begins for scheme it is hoped will reduce through-traffic and improve air quality

Paris authorities have begun limiting traffic in a large zone of the city centre, with police alerting drivers that they are now banned from driving through the French capital’s central four arrondissements and risk a fine if they do so after next spring.

The so-called “limited traffic zone” (ZTL), home to about 100,000 people and 11,000 businesses, is part of a broader push by the socialist mayor, Anne Hidalgo, to restrict traffic and encourage cycling and public transport use across the car-clogged city.

Millions of teenagers in Africa have undiagnosed asthma – study

Rapid urbanisation thought to be damaging adolescent health, as researchers say need for medication and diagnostic tests is urgent

Millions of teenagers in Africa are suffering from asthma with no formal diagnosis as the continent undergoes rapid urbanisation, researchers have found.

The study, published in the Lancet Child and Adolescent Health, involved 27,000 pupils from urban areas in Malawi, South Africa, Zimbabwe, Uganda, Ghana and Nigeria. It found more than 3,000 reported asthma symptoms, but only about 600 had a formal diagnosis.

Water companies raise bonuses to £9.1m despite record sewage discharges

Third of total comprises bonuses at Severn Trent as indebted Thames nearly doubles payouts to executives

Bonuses for water company bosses in England and Wales rose to £9.1m this year despite record sewage discharges into rivers and seas.

More than a third of that total comprised bonuses at Severn Trent, which was fined £2m this year for “reckless” pollution but lifted its bonuses to £3.36m.

Thames Water almost doubled its payouts to executives, from £746,000 in 2021-22 to £1.3m in 2023-24, despite its CEO quitting halfway through the year.

Data from Companies House, analysed by the Liberal Democrats, show that overall bonuses increased from £9.013m last year to £9.127m this year.

The payouts pile further pressure on the regulator, Ofwat, to intervene in the decisions of water company boards. Last year, raw sewage was discharged for more than 3.6m hours into rivers and seas, a 105% increase on the previous 12 months.

The ‘active transport’ ideas from around the world that could make Australians healthier and our cities cleaner

Policies such as cash payouts for bicycle commuters have knock-on effects including reduced pollution and better physical and mental health

It’s time for a major rethink of transport in Australia, experts say – and, while some new ideas may meet resistance, “these are not ideas from radical left Scandinavian pot-smoking greenies”, Prof Matt Burke says.

Policies lumped together as “active transport” include proposals to offer rebates for people who ditch their cars for public transport, or cash payouts for people who cycle to work.

Only one-third of Europe’s surface water qualifies as good or better, study finds

Data compiled by EEA shows quality of water bodies falls far short of target first set for 2015 and since extended to 2027

Only about one-third of Europe’s surface water is in good health or better, a report has found, despite an EU target first set for 2015 to bring all bodies of water up to good quality.

About 37% of Europe’s surface waters qualified as having at least a good ecological status and 29% a good chemical status in 2021, according to data from 19 member countries compiled by the European Environment Agency (EEA). The original deadline for the EU target has been extended to 2027 but data suggests this is on track to be missed by a wide margin.

Labour used water industry analysis to argue against nationalisation

‘Economically illiterate’ Defra letter sent to anti-sewage groups cites 2018 report commissioned by water companies

Labour used “economically illiterate” analysis paid for by water companies in order to argue against the nationalisation of the sector, the Guardian can reveal.

In an official letter recently sent to anti-sewage groups, civil servants cited a paper by the Social Market Foundation as a reason to avoid nationalisation as part of its review of the sector. The report from 2018 was commissioned by United Utilities, Anglian Water, Severn Trent and South West Water.

Plutonium levels near US atomic site in Los Alamos similar to Chornobyl, study finds

Much of the land near the atomic bomb’s birthplace was converted to recreational areas, but toxic waste remains

Soil, plants and water along popular recreation spots near Los Alamos, New Mexico, the birthplace of the atomic bomb, are contaminated with “extreme concentrations” of plutonium, a new study has found, but calls for the federal government to act have been dismissed.

Michael Ketterer, a Northern Arizona University scientist and lead researcher on the project, said the plutonium levels in and around New Mexico’s Acid Canyon were among the highest he had ever seen in a publicly accessible area in the US during his decades-long career – comparable to what is found in Ukraine at the site of the Chornobyl nuclear disaster.

Industry acts to head off regulation on PFAS pollution from semiconductors

The Chips and Science Act has led to a production boom but experts say it could generate huge amounts of toxic waste

Producers of PFAS chemicals and semiconductors, a key part of most electronics, have formed a group that develops industry-friendly science aimed at heading off regulation as the facilities release high levels of toxic waste, documents seen by the Guardian show.

The group, called the PFAS Consortium, was formed during a boom in domestic semiconductor production spurred by the Chips and Science Act that has led to $825bn in investment aimed at shoring up the industry.

‘It could be months or years’: Walsall canal faces long road back to health after chemical spill

Charity is considering removing some of the water and there is also concern over the sediment on the canal floor

When sodium cyanide leaked into a Walsall canal this month, leading to major incident being declared and miles of the waterway closed off, the Canal & River Trust was working in uncharted territory.

The charity is used to fighting pollution in the waterways that crisscross the country, but this type of chemical – and the extreme risk to public health that came with it – was not something it had tackled before.

London City airport expansion given green light by ministers

Climate campaigners criticise decision to allow capacity to increase from 6.5m to 9m passengers a year

Ministers have approved London City airport’s application to expand, in a decision that has disappointed climate campaigners.

The airport submitted a proposal to increase capacity from 6.5 million to 9 million passengers a year by putting on more weekend and early morning flights. Local campaigners and Newham council opposed the move, arguing the air and noise pollution would affect people living nearby and that it could potentially increase carbon emissions.
