Dr. Cathal Gallagher:

I do not have the exact figure because it changes but I can certainly look at it and come back. Other water sampling goes on. There is a broad range of different types of sampling. One of the latest programmes we have looks at the environmental parameters for climate change. We have a number of index catchments that look at various measures, including temperature and water quality. We are involved in a broad range of programmes. One of the advantages of the type of operation we have is that we are regionally based. We have access to an awful lot of catchments. Many of the local staff have a lot of expertise and insight into their performance.
