Farmers across England begin ‘Return to Sender’ programme for chemical-laced sewage sludge – April Fools

Concerned farmers across England have today announced a coordinated initiative to return sewage sludge contaminated with so-called “forever chemicals” back to the water companies that supplied it, citing growing fears for soil health, river health, food safety, and their own reputations.

The move follows mounting evidence that sludge spread on farmland contains PFAS chemicals, microplastics, and industrial residues that persist indefinitely in the environment. 

Much of this cocktail originates from chemical and manufacturing industries, which helpfully design substances robust enough to survive heat, pressure, sunlight, and, it turns out, most attempts at water treatment. Farmers say they are no longer willing to act as what one described as “the final chapter in a very long and poorly edited industrial experiment.”

Under the scheme, informally dubbed “Sludge Back Guarantee™”, farmers plan to deliver unwanted biosolids directly to water company offices, treatment works, and executive car parks, accompanied by polite notes reading: “Thanks, but no thanks. Please enjoy your product.”

We were told this stuff was a ‘nutrient-rich soil improver’,said one arable farmer from the Midlands.Turns out it’s more of a forever-chemical retirement plan. We grow wheat, not legacy pollution.

Farmers stress that they are not anti-recycling, anti-fertiliser, or anti-water company in principle. They are, however, reluctant to spread materials that behave less like compost and more like a time capsule for industrial chemistry.

Clean river campaigner and responsible farming advocate Hugh Fearnley-Whittingstall said:

“British farmers have spent decades improving soil health and food standards, so it’s reassuring to know they’re now trusted to warehouse a selection of synthetic chemicals that don’t degrade, can’t be removed, and weren’t invited. It’s a bold new diversification strategy.”

The action follows growing concern within the farming community that they are being used as a convenient outlet for sludge generated not just from households, but from industrial effluent containing persistent synthetic chemicals. Critics say the system works with admirable efficiency: chemical companies produce substances that resist breakdown, water companies circulate them through treatment systems not designed to remove them, and farmers are then offered the end product as a sustainable soil enhancer.

River Action’s Head of Campaigns Amy Fairman said:

“This arrangement has the elegance of all good cost-saving exercises: the pollution stays, the risk travels along our rivers, and responsibility quietly disappears. Farmers aren’t rejecting recycling – they’re declining to be mistaken for hazardous-waste facilities.”

Farmers say they are now calling on:

  • Chemical manufacturers to stop testing the limits of eternity in products that end up in wastewater
  • Water companies to stop accepting industrial chemical waste into systems that produce agricultural sludge (or at least stop calling the result ‘beneficial’)
  • Government to update decades-old rules and recognise that ‘persistent’ is not a synonym for ‘harmless’
  • Regulators to require full disclosure of what is actually in sludge, ideally before it is spread rather than several decades afterwards

“Food security doesn’t mean ‘spread now, regret indefinitely’,said a mixed farmer from Yorkshire.Our soils are our pension, our business, and our responsibility. We’d quite like them not to double as a long-term chemical archive.

Water companies contacted for comment said they were “reviewing the situation” and confirmed that while sludge was safe “within current guidelines,” they would “prefer not to receive it back.”

The Department for Environment, Food and Rural Affairs reminded farmers that April 1 is “not an appropriate day to trial reverse logistics for biosolids,” before adding that it would “continue to engage constructively with all stakeholders and, where possible, reality.”

Farmers insist the message is serious, even if the timing is not.

We don’t want sludge wars,said one. “We just want clean water, clean soil, and slightly fewer forever chemicals. Ideally none, but we’re trying to be realistic.”


Notes to editor

This press release is issued as part of April Fools’ Day and the “Return to Sender” programme described above is satirical.

However, the practice of spreading sewage sludge on agricultural land in England is very real. Sewage sludge can contain PFAS “forever chemicals”, microplastics, and other industrial contaminants that are not routinely removed during treatment and can persist in soils and waterways.

Farmers’ concerns about being asked to spread contaminated sludge, the lack of transparency over its contents, and the long-term risks to soil health, water quality, food safety, and public trust are genuine and widely shared.

Public concern is also significant. A recent YouGov poll conducted for River Action found that 92% of people in the UK believe water companies must ensure sewage sludge used on farmland is not contaminated. The same polling shows that 61% of respondents were unaware that sewage sludge from water companies is commonly spread on farmland, while half (50%) believe the practice poses risks to health and food quality.

Government White Paper on Water Reform Falls Short of Real Reform

Today, the government has released its long-awaited Water White Paper. This White Paper sets out the Government’s response to the recommendations made by Sir Jon Cunliffe’s Review of the water sector in 2025. Although there are some welcome steps, it falls short of the ambition and enforcement needed to Rescue Britain’s Rivers.

CEO of River Action, James Wallace said:

“The publication of the Water White Paper signals the Government recognises the scale of the freshwater emergency, but lacks the urgency and bold reform to tackle it. 

“Proposals for a new water regulator, including the appointment of a Chief Engineer, alongside infrastructure ‘MOTs’ and no-notice inspections of water companies, are welcome steps, provided the regulator is truly independent, equipped with real powers and funded by The Treasury to hold polluters to account.

“However, major gaps remain. These reforms will fail unless the privatised model is confronted head-on. The crisis is the result of a system that prioritises short-term profits and shareholder payouts over people, rivers, and public health. 

“Special Administration must be the clear route to a public benefit model for water. It is the mechanism by which failing water companies can be taken out of extractive ownership and restructured so that investment serves customers and the environment, not short-term results. This requires clear, published triggers for Special Administration and a firm commitment to reform ownership and finance so that profits are secondary, long-term, and conditional on strong environmental performance and public benefit.

“We are also concerned about the emphasis on smart meters, which risks placing responsibility on households when water companies have failed for decades to invest in ageing, leaking infrastructure. Millions of litres of water are lost every day, and consumers should not be asked to pay for corporate underinvestment.

“Finally, while agricultural pollution is acknowledged, the proposals do not yet go far enough in ambition or enforcement needed to tackle this problem at source. The abomination of sewage sludge epitomises the challenge: farmers pay water companies for sludge to spread industrial ‘forever’ chemicals on the land that grows our food. The real test of these reforms will be whether they deliver a system that puts public and environmental protection ahead of corporate profiteering.”

As the government prepares its upcoming Water Reform Bill, we will continue to push for real, meaningful reform and press for tougher enforcement, stronger accountability, and a water system that works for people and nature — not lining the pockets of polluters.

Toxic sludge scandal: The hidden threat lurking in our fields

By Amy Fairman, Head of Campaigns, River Action

Across the UK, millions of tonnes of toxic sewage sludge is being dumped on our farmland every year. Marketed as “fertiliser,” this hazardous waste produced by water companies can contain a cocktail of microplastics, heavy metals, and dangerous “forever chemicals” that persist in the environment and accumulate over time. Shockingly, around 90% of this sewage sludge is ending up on the land that grows our food, leaching pollution into our soils and rivers.

This isn’t just a failure of transparency, it’s a ticking environmental time bomb that could even lead to soils becoming unable to support crop growth.

Thanks to our legal challenge against the Environment Agency, the Government is finally under pressure to confront this scandal head-on. And behind the scenes, water companies are panicking. A recent investigation by Unearthed has exposed their growing fears: if new regulations come into force to stop this reckless sludge spreading, they’ll be left with millions of tonnes of waste without a home.

And their plan? To make you, the public, pay for the clean-up. Again.


A broken system

Sewage sludge is the solid material left behind after wastewater is treated. It’s a necessary part of managing sewage. However, this sludge is not harmless compost. It’s laced with toxic pollutants, including PFAS (forever chemicals linked to cancer and infertility), microplastics, and heavy metals that poison the land and waterways. Yet water companies have been quietly offloading this waste onto UK farmland for decades, with little accountability and woefully inadequate oversight.

What’s worse, the water industry has not been upfront about what this sludge contains. Farmers have unknowingly spread this material across their fields, and regulators have turned a blind eye. Shockingly, the Environment Agency has axed its pledge to test sewage sludge for microplastics and ‘forever chemicals’ – an issue exposed recently by Fighting Dirty in its legal challenge.

But now the pressure is mounting for the Government to step up.


River Action’s legal push for change

Last year, we launched a legal challenge against the Environment Agency and the Government for failing to enforce the rules on sewage sludge spreading. Our case argued that the authorities were breaching their legal duties to protect human health and the environment by allowing excessive muck spreading that exceeds the immediate soil and crop nutrient needs, leading to nutrient runoff into waterways.

The result? The Government is now reviewing its enforcement guidance, a crucial step toward stopping the spread of toxic waste on our land and rivers. This could force water companies to find safer, cleaner ways to manage their sludge. But there’s a catch: if that happens, they’re already warning they’ll ask Ofwat for an emergency rise in water bills to cover the cost.

Let’s be clear: the public should not foot the bill for the water industry’s environmental negligence. We’ve already paid the price through polluted rivers, poisoned soil, and mounting ecological damage. The companies responsible must be made to clean up their own mess.

Time to act

This is a defining moment. For too long, the water industry has prioritised profit over public health and environmental protection. That must end.

Together with Greenpeace, we are calling on the new Secretary of State for Environment, Steve Reed, to take urgent action:

  • Stop the spreading of toxic sewage sludge on farmland
  • Make water companies pay the full cost of disposing of this waste safely
  • Introduce proper regulation and legal limits on the content of sludge used in agriculture

Sign the petition today and demand the Government puts an end to this toxic scandal. Let’s hold water companies accountable and ensure our land, rivers, and future are protected from pollution.
