Mr. David Flynn:

Sure we do. It is through programmes like the Environmental Protection Agency, EPA, the Geological Survey of Ireland and the agricultural catchments programme, ACP, which is looking in extreme detail at catchments and how nitrogen phosphorous behaves. In terms of the things that influence it, there is the rainfall; the topography of the local area, such as the slope of it; the soil type, for example, whether it is heavy or light soil; and the bedrock that underlies that. None of those can be controlled. It is what it is. What can be controlled is the load. Depending on those other factors, the load has an impact. Farm practice can also be controlled - how and when that load is applied. They are the criteria. We said earlier that it is highly variable across Ireland. At a landscape scale, we are seeing the issues.

I go back to what Senator Lombard said earlier about Timoleague. There are hugely positive results coming out of the Timoleague catchment that are very favourable and look very promising. They still have a long way to go. They are at the lowest level since 2009. It is about 5 mg per litre. It is still twice what you would want in the estuary and higher again than what you would want in the river. The issue with that is we are not seeing that replicated in the national data sets across the country. The question to look at then from the ACP is what is happening in Timoleague that could be replicated through regulation or other voluntary measures at a landscape scale that would make a difference in terms of keeping that trend going. As I said, there is quite a lot going in that.

In terms of the data sets-----
