Thames WaterBlitz


The Thames WaterBlitz is a campaign to collect as many water samples as possible (in a short period of time) from across the Thames catchment. Blitz events are held throughout the year and create an invaluable snapshot of the health of our rivers that will help to direct future conservation efforts.
