Do you want to do your own Citizen Science testing to check the water quality in your river?  We have a set of materials to help you. You will find guidance and links to resources in these two briefing documents:
1. Here is the protocol we have developed and which is approved by the Environment Agency [attach protocol] for testing the water for sewage pollution
2. Here is what you need if you want to test the water quality in a stretch of a river.
