River Avon: Residents claim pollution is killing wildlife in Bristol

Something smells fishy in Bristol

If you live near the River Avon in Bristol, you might have noticed the vibes are off. For over a year, residents have been reporting a nasty, oil-like substance bubbling up to the surface of the river. It’s leaving a rainbow film on the water, smelling like a gas station, and locals say it’s lowkey killing off the wildlife.

Nicola Irvine, who lives in the Crews Hole area, has been trying to get the Environment Agency (EA) to do something about it since July 2025. She told the BBC that trying to get them to investigate has been like "pulling teeth." Her partner, Toby White, added that the smell gets so bad sometimes it’s like living on a petrol station and can even trigger headaches.

Is the EA ghosting the problem?

Irvine says the impact on the local ecosystem is heartbreaking. She used to see 30 to 40 ducks in that stretch of the river, but now it’s just a handful. She’s found dead fish, ducks, and ducklings, and while it’s hard to prove, she’s convinced the pollution is to blame. The heatwaves this summer made the stench even worse, forcing her to take migraine medication.

So, what does the EA say? They’ve officially labeled this a "category three" incident, which basically means they think the environmental damage is limited. They’ve suggested the source might be old pollution from a 19th-century tar works that operated in the area until the 1980s, but they are still investigating.

Real talk: that classification hasn't sat well with locals, especially since an internal report from 2022 leaked that the agency was told to ignore category three and four incidents due to funding issues. It’s giving bureaucratic mess, no cap.

The fallout

Local resident Dominic Linnell, who walks his dog by the river daily, says he’s seen the oil slick and dead wildlife for over two years now. Another neighbor, Tristan Dhalla, says he’s noticed it since moving in five years ago, with some residents claiming the issue goes back a decade.

While Wessex Water says their systems aren't involved, Bristol City Council is reportedly sharing records with the EA to help move things along. Meanwhile, the EA is also looking into a separate, equally gross incident at nearby Brislington Brook involving foam and dead fish. It’s a W for the volunteers for speaking up, but the situation as a whole is an absolute L.

Why it matters

When a community's local environment starts dying, residents shouldn't have to fight tooth and nail for someone in power to pay attention. If an agency tasked with protecting our water is ignoring 'minor' pollution reports, the ecosystem—and the people living in it—are left to suffer the consequences.
