Become a Citizen Scientist

One of the best ways you can help us make a lasting difference to London’s rivers is by taking part in one of our free citizen science training courses. They are fun, free training sessions which empower you to gather data in a way that advances scientific knowledge and guides action on pollution and river restoration.

Our citizen scientists collect a wide range of data including water quality, aquatic invertebrates and plastic pollution.

We use the data you collect to effect change by sharing it with key decision makers like the Environment Agency, Thames Water and local councils. By sharing the data with academics, universities and the media we raise awareness of the issues that affect our rivers.

The high-quality long-term data collected by our citizen scientists is improving knowledge about the health of London’s waterways and influencing change for the benefit of rivers, wildlife and communities.
