The Environment Agency said there was no “obvious environmental impact” after a resident found contaminated water flowing to a popular boating lake in Newquay. White residue was spotted flowing from a drain running through the Trenance Valley on Sunday afternoon (April 24) and residents have raised concerns about the impact it could have on wildlife and the area .

Local resident Richard Curtis said he noticed the water running white for several hours and reported it to the Environment Agency (EA). Sharing a post about the contamination on Facebook, Richard explained that there were bubbles in the water and there was a strong smell of paint.

He told CornwallLive it wasn’t the first time something like this had happened: “At the source it was bubbling and smelling like masonry paint. It’s probably been going on for about five hours in total and this is not the first time that I’ve reported river pollution to the EA.

“There are days in the summer when there has been no rain for about a week and in the morning the river is crystal clear, then without rain the river is either brown or sometimes black. However, I have never saw that part of the river was flowing white so I have no idea where it came from.”

Despite initial concerns that the water could pollute the nearby boating lake – a popular spot for families – the Environment Agency confirmed the waterway was clear and there were no “obvious” impact on the area. However, he also said it was unclear where the pollution came from in the first place, but that further investigations would take place if it happened again.

An Environment Agency spokesperson said: ‘We are grateful to the person who brought this to our attention and for being environmentally conscious. With their extensive information, we were able to investigate and confirm that although there is tailings around a drain that serves the stream, the stream is clear with no obvious environmental impact.

“We suspect the drain is bringing in surface water from the road. But the only way to find the source of the pollution is to trace it if it happens again. If you see pollution in rivers or streams, report it to our 24/7 emergency hotline on 0800 807060.”
