Muddy Walks app

You can be the eyes and ears of the catchment by joining our Muddy Walks Pollution Patrol team. 


We use the information the team provide to give us a picure of what's polluting the river. 
We run regular Muddy Walks Pollution Patrol training workshops. Drop us an email if you'd like to join the next one and we'll show you how you can use your smartphone to share the location of potential pollution hotspots with us.

It's important that you report active pollution incidents to the Environment Agency and Thames Water, particularly if the pollution is causing an obvious risk to the environment. Contacts for this are here.
