One previous report of pollution at the stream was reported on by The Packet last March in which a 'blue-white coloured liquid' was seen by two Falmouth locals who were out walking on the nature reserve.

On that occasion, one of the walkers had described how the liquid smelt like acrylic and had continued to pour out of the pipe and downstream for around 40 minutes.

After collecting images and video of the stream, the walker contacted the Environment Agency and sent in the pictures and videos that were captured.
