Spring WaterBlitz 

Help us understand fresh water near you 

We need your help, sign up to take part in a WaterBlitz near you!

We believe that we cannot truly understand what is going on in our rivers without collecting evidence to demonstrate how healthy, or unhealthy, they really are. We will use data collected by you during the WaterBlitz to identify clean waters, to pinpoint pollution hotspots, and to help inform where, who, when and how remedial actions should be taken.


Upcoming WaterBlitz Events

Paris WaterBlitz

The River Seine and many of Paris' other waterbodies have been impacted by urban activities and the loss of green buffer areas. 

We're bringing the WaterBlitz back to Paris from 4-7 June, so don't forget to register for your free testing kit. 

Luxembourg WaterBlitz

Registration is now closed - thank you for all your interest.

Luxembourg has experienced a large population increase over the past 20 years, negatively impacting biodiversity and water quality. 



This spring's Thames WaterBlitz is now fully subscribed! 

We're thrilled that so many of you wanted to take part. If you didn't manage to sign up this time you can register your interest in future events below. 

Dublin WaterBlitz

This spring's Dublin WaterBlitz is now fully subscribed! 

We're thrilled that so many of you wanted to take part, thank you. 

About the WaterBlitz

In urban areas around the world, our natural water is suffering from pollution and other human impacts. You can help us protect our water by providing vital information on water quality, local land use, and nearby environment. We could never collect this much information ourselves, so we are asking you to help us.

This spring we're bringing the WaterBlitz to the Thames Valley for an eleventh time and to Dublin, Paris and Luxembourg for a second time. Having repeated measurements is vital to provide robust, scientific evidence, which can be used to make real changes.
