We start today returning to the issue of river pollution with news of a serious incident in the Yorkshire Dales. Elsewhere we’ve news on:

River pollution incident under investigation

An investigation has been launched by the Environment Agency(EA) after reports of dead fish and a river turned green with slurry pollution.
The incident near Leyburn in North Yorkshire was spotted at the end of April although it’s not known how long the slurry - a mixture of water and manure used as a natural fertiliser for crops - had been spilling into Garriston Beck .
An EA spokesperson said: “We are investigating the slurry incident near Leyburn and, after attending the site, can confirm that the pollution has stopped.
“Our focus has turned to establishing the cause of the incident and assessing environmental impacts to tributaries of the River Ure.
“We would like to thank members of the public for reporting this incident to our hotline on 0800 80 70 60.”
The spill was also reported to local river campaign groups who have been working with volunteer citizen scientists to monitor pollution levels in both the River Swale and the River Ure.
A spokesperson for Save Our Swale said: "We only know of the slurry spill incident at Garriston Beck from what was reported to us by members of the Stop Ure Pollution (SUP) campaign.
“We are pleased that it is being investigated by the Environment Agency which is exactly what should happen when pollution incidents of this nature occur. We are concerned about the report that the reported slurry spill could, though, end up in the Swale via Hunton Beck!
This is not within the catchment area of the Save Our Swale campaign which runs from Wainwath in the Dale through Richmond and down to Brompton but nonetheless, any potential for pollution anywhere on the Swale is concerning and the public have a right to be informed.”
Environmental damage
If slurry spills into the water, it can kill marine life and other wildlife, leading to environmental damage. These incidents are taken very seriously and can result in significant fines and penalties, including fines of up to £50,000 issued by the EA.
One of the primary causes of river pollution from slurry is the release of harmful chemicals and nutrients during its decomposition. When slurry decomposes, it releases nutrients such as nitrogen and phosphorus, which can cause excessive growth of algae and other aquatic plants in rivers and other bodies of water. This eutrophication process, can lead to a reduction in oxygen levels in the water, causing harm to fish and other aquatic life.
Next steps
We’ll follow up on the EA investigation to establish the cause of the incident and any enforcement response. However, experience suggests this is unlikely to have a speedy resolution.
Regular readers may recall the serious slurry pollution incident which took place in April 2023 at Skeeby Beck. At the two year anniversary of that incident, we submitted another Freedom of Information (FOI) request to EA asking about its investigation of the Category 1 incident.
An EA spokesperson responded saying: "This case is still ongoing and is near the stage of being finalised, however, a time frame cannot be provided due to it being a complex process."

🌏 England’s peat deposits - mostly in he North - are one of our most valuable national assets. They’re our largest carbon store, they filter most of our fresh water and help defend communities against flooding, and they’re home to irreplaceable plants and wildlife. Yesterday Natural England launched a new nationwide map of peat and peaty soils, The England Peat Map. The map has the most detailed national coverage to date for peat depth, peatland vegetation, upland drainage channels, and upland bare peat, which are all important in determining peatland condition. It’s published on an open access, easy to use web viewer and across a number of freely accessible government platforms.
