THE sight of streams turning a luminous green is not unheard of in the UK, with the strange phenomenon turning up in Leeds, Stockport and Sussex in recent years.

But yesterday it was Norton's turn. This image of a stream near the Westfield estate was shared on social media by Peter Aston Bellamy.

Peter said that he contacted the Environment Agency about the water, and that a day later the stream is now running clear.

It's understood that the cause of the colouration is a tracing dye used by water companies - and occasionally private individuals - in watercourse and drain investigations.

A spokesperson for the Environment Agency said that the green colour is caused by something called 'fluorescein' dye. They said in this case it was likely to have been a private individual.
