Drugs in urine from Glastonbury festival ‘pose threat to rare eels’

Levels of illegal drugs found running through a river near Glastonbury festival were so high they could be harming wildlife, scientists have warned.

Researchers discovered environmentally damaging levels of substances such as MDMA and cocaine in the water after the last festival in 2019, which could be affecting wildlife further downstream, including rare populations of eels.

The experts are now urging greenfield festivalgoers to use the official toilets provided by organisers, as it is thought the drugs can enter nearby rivers through public urination.

Dan Aberg, a Masters student in the School of Natural Sciences at Bangor University, worked with Dr Daniel Chaplin from the Centre for Environmental Biotechnology (CEB) to measure levels of illicit drugs before, during and after the Glastonbury Festival when it was last held in 2019.

Samples were taken from the Whitelake River both upstream and downstream of the festival site.

The study found MDMA concentrations quadrupled the week after the festival, suggesting long-term release from the site.

They also discovered cocaine concentrations rose to levels known to affect the lifecycle of European eels, a protected species.

Mr Aberg said: “Illicit drug contamination from public urination happens at every music festival.

“The level of release is unknown, but festivals undoubtedly are an annual source of illicit drug release.”

He added: “Unfortunately, Glastonbury Festival’s close proximity to a river results in any drugs released by festival attendees having little time to degrade in the soil before entering the fragile freshwater ecosystem.”

The researchers suggested studies should be conducted into possible treatment via environmentally friendly methods, such as constructed treatment wetlands (CTWs), in order to minimise the release and impact of illicit drugs from festivals.

Information on the harmful effects of public urination should continue to be provided to festival attendees to reduce the contamination of natural resources, they added.

Dr Christian Dunn, from Bangor University, said: “Our main concern is the environmental impact. This study identifies that drugs are being released at levels high enough to disrupt the lifecycle of the European eel, potentially derailing conservation efforts to protect this endangered species.

“Education is essential for environmental issues, just as people have been made aware of the problems of plastic pollution, and Glastonbury have made great efforts to become plastic-free, we also need to raise awareness around drug and pharmaceutical waste – it is a hidden, worryingly-understudied yet potentially devastating pollutant.”

But Micheal Eavis, founder of Glastonbury festival and owner of its Worthy Farm site, called the findings “absolute balderdash”.

He told The Times: “We move heaven and earth to keep urine out of the river. We have a whole lot of people monitoring the river every two hours.

"[Festival goers] don't urinate in the river because we have so many people stopping that from happening. And they don't pee on the grass outside the river either. The people who come to this festival are so environmentally concerned. They are incredibly good people, so conscientious."

A spokesman for Glastonbury Festival added: “Protecting our local streams and wildlife is of paramount importance to us at Glastonbury Festival and we have a thorough and successful waterways sampling regime in place during each Festival, as agreed with the Environment Agency. There were no concerns raised by the Environment Agency following Glastonbury 2019.

“We are aware that the biggest threat to our waterways - and the wildlife for which they provide a habitat - comes from festivalgoers urinating on the land.

“This is something we have worked hard to reduce in recent years through a number of campaigns, with measurable success.

“Peeing on the land is something we will continue to strongly discourage at future festivals. We also do not condone the use of illegal drugs at Glastonbury.

“We are keen to see full details of this new research, and would be very happy to work with the researchers to understand their results and recommendations.”
