Yearly Nitrate Readings (FOI)

​Request

1

Please could I have a breakdown of the yearly average nitrate reading in the water for each of the following catchments from 2020 to date: Le Mourier Valley catchment, the Bellozanne Steam catchment, the Greve de L’Ecq catchment, the Queens Valley Side Stream catchment and the Quens Valley Stream catchment.

2

If there is test data Neonicotinoid pesticides that would be welcome too.

3

Can I also please have the number of algal blooms in Jersey waters recorded in each year since 2014, and how much is spent each year cleaning them?

4

Finally, could I please have the predicted volume of overflow liquid that each spillage location in Jersey would give off if it released overflow for 1 hour?

I.e 1 hour of sewage spillage at the Weighbridge location may be different to 1 hour at the Le Dicq - what volume does each site release when in use for a given time?

Thank you very much for your help.

It should be noted, if there is a storm spillage when the foul sewer network gets inundated with surface water. only the durations are recorded. However, we would expect the spills to be larger in volume the closer to Bellozanne (e.g Le Dicq & West of Albert).
