A WaterBlitz is a FreshWater Watch activity for the whole community. Usually hosted over one weekend, members of the public can sign up to receive a free water testing kit and become citizen scientists by testing a water body local to them. The data collected by hundreds of people over this same time period gives us an accurate and comparable snapshot of water health within a region. Learn more with our WaterBlitz leaflet.
In the UK, events are held across the Thames and Bristol Avon catchment areas. The WaterBlitz also runs in Ireland, France, Luxembourg, Netherlands, Italy and Sweden.

Our friends at the Bristol Avon Rivers Trust (BART) have organised WaterBlitz events since 2016. This year, the team were on hand to give sampling demonstrations on the River Biss and Bristol Frome!
The River Seine and many of Paris' other waterbodies have been impacted by urban activities and the loss of green buffer areas. Citizen science data can help to monitor sites across the city. This event was held in partnership with École des Ponts ParisTech.
Alongside our 11th Thames WaterBlitz, we were joined by citizens from Ireland and Luxembourg. In total, 1,214 volunteers took part, recording 1,568 measurements across all three locations!
An amazing 879 volunteers took part in our largest ever Thames Valley event! Click below to read the full WaterBlitz report and view an interactive data map.
Our first ever Pan-European WaterBlitz saw events held simultaneously in London, Dublin, Paris and Luxembourg. Over 1,100 volunteers took part, uploading nearly 1,000 water quality measurements!
