The reason a stream in a popular Bristol park turned green has been revealed. On Friday last week (January 6) locals had been asking questions about a tributary of the River Frome that had turned green in Eastville Park.
At the time, no-one was sure what had happened. However, the Environment Agency has got back to Bristol Live with clarification as to why this was the case.
It had already suggested by some on Twitter that the colour change was due to a tracing dye, used by water companies or potamology students to monitor measurables such as water flow and velocity. And this has now been confirmed by the experts.
