โ€˜Like fly-tippingโ€™: ministers ignoring pleas to cut sludge fertiliser use Exclusive: Defra warned three years ago of farmland contamination by water firmsโ€™ sewage-derived product

This includes staff at the regulator warning 3 years ago that practically all microplastics that enter sewage treatment works end up in sludge bound for farmland.

My investigation has revealed that this is estimated to be 22 TONNES of microplastics per day.

These docs have revealed the extent to which the EA has sought to persuade the government to implement its plans to tighten the regulatory net on sludge, including eye-watering evidence of the risk of not doing so - and how the agency was ignored.

Last year, lawyers representing @fightingdirty.bsky.social took the EA to court over whether its decision to remove a deadline for reforming sludge regulations was unlawful. The group lost its case - but via FOI I got hold of the docs submitted by the EA.

Huge news โš ๏ธ

The government has sat on plans to tighten sewage sludge rules for 3 YEARS despite the EA warning of serious contamination from pollutants like #PFAS & #microplastics!

We might have lost our court case, but the papers arising from it, analysed by the brilliant Tess Colley, are a goldmine of information about the disgraceful way in which farmers have been misled by the water companies and ministers have failed to act.

โ€˜A Trojan horseโ€™: how toxic sewage sludge became a threat to the future of British farming Sludge used as fertiliser on farmland contains harmful chemicals that scientists suspect are entering food chain

This follows @rachelsalvidge.bsky.social of @watershed-i.bsky.social's story where a water industry insider described sludge as "a Trojan horse" with toxic contaminants (PFAS, microplastics etc) threatening "the long-term sustainability of humanityโ€™s farmland".

Never one to mince his words, @georgemonbiot.bsky.social, co-founder of @fightingdirty.bsky.social, said "farmers are being deceived by the water companies - theyโ€™re being misled, and this could have very serious implications for their future livelihood".

Last year I revealed how sludge has been sold to UK farmers by water companies containing a banned โ€˜forever chemicalโ€™ - a suspected carcinogen - at levels in excess of those considered safe in emerging science because of potential for crop uptake.

โ€˜I donโ€™t know how weโ€™ll surviveโ€™: the farmers facing ruin in Americaโ€™s โ€˜forever chemicalsโ€™ crisis Maineโ€™s disaster from PFAS-contaminated produce is causing farms to close and farmers to face the loss of their livelihoods

This matters for lots of reasons, including this pollution potentially being taken up by crops. But also for farmers. In the US, some have been put out of business because of the levels of contamination found on their land - & in their bodies - linked to sludge.
