At around 3.30pm on Wednesday 8 August, the Wandle was seriously affected by a brief but deadly surge of pollution that appeared to originate at the top of the Mill Green branch of the river in Sutton. 

Many specimen fish of all species were killed as the river rose suddenly and took on the grey-green colour and appearance of “chopped seaweed”, according to one witness.

We would like to thank everyone involved in trying to save the dying fish, particularly the landlord of the Queen’s Head pub on Mill Green, who made sure to get a water sample at the height of the incident. 

Our investigation of this catastrophe is ongoing, in partnership with the Environment Agency and concerned members of the local community.  Look here for our forum blog of the latest information.
