Mr. Dara Lynott:

A map would have been produced by the Geological Survey of Ireland which would have classified groundwater as vulnerable. I am not sure what the other characterisations would be. I would imagine that some parts of the north west would have been classified as vulnerable. Again, the criteria would have been the type of soil in front of it, whether there was exposed bedrock and various things on that but I do not have the map to hand.
