The strangely-coloured substance appeared in the water at the weekend
The Environment Agency has investigated a coloured substance in a Cambridge river. A fluorescent yellow substance was spotted in the River Cam in Cambridge on Sunday (July 26).
The Environment Agency was made aware of the substance and has investigated. An EA spokesperson said: “An environment officer went to the river to investigate. We also talked to Cam Conservators, which manages the river.
“As is often the case, substances on the surface go as quickly as they appear, and there was nothing for us to see.” The EA added that the hot weather can change the colour of rivers and also produce algae.
The spokesperson added: “This looked like algae, but it is normally green, blue or brown. It looks like the river is now okay.
“Anyone with new concerns about the Cam or any river is urged to call the Environment Agency’s 24-hour incident hotline: 0800 807060.”
