Testing Time at the Tolka

As part of our commitment to support local biodiversity, Castleknock Tidy Towns took part in the Waterblitz '21 event this weekend.

This simply involved two volunteers collecting a water sample from the Tolka River (just off Dunsink Lane) and then using a little test kit to check it for Nitrates (N03) and Phosphates (P04). Results were not too bad - see colour chart!
