The Trust is coordinating an expanding programme of water quality tests in the Wey catchment. Establishing a baseline view of the river waters allows us to understand where there may be problems, and to see where possible pollution events occur.

Using chemical tests for phosphate, nitrate and such as pH levels, together with kick sampling to assess key invertebrate species, we are able to record the state of the river, and share these data widely. The aim of the Trust and the groups along the river who carry out the tests is to provide a positive contribution to help understand and improve the eco system in which the river is a key element.

The Woking Testing Hub monitors the river and tributaries between Guildford and Weybridge.
