Water quality surveys
Our citizen scientists have been collecting important water quality data to help us understand where improvements for the River Chess could be made.
In the first year of the project, we created a baseline assessment of water quality in the Chess catchment.
We knew this would help us identify what major issues the River Chess faced and could then decide how to try and tackle them using citizen science to fill in any knowledge gaps.
What water temperatures is the River Chess reaching during summer heatwaves, and are these temperatures likely to be stressful for key species?
Storm tank overflows
How do storm overflow events from Chesham sewage treatment work impact overall water quality of the River Chess?
How are ammonium, turbidity and dissolved oxygen levels impacted by sewer misconnections in urban environments (Chesam, Rickmansworth)?
What is causing an increase in phosphate and nitrate levels in the mid-reaches of the River Chess between Sarratt and Solesbridge Lane?
Where are the worst problem areas for siltation of sediment in the River Chess, and where is the sediment coming from?
