Galway residents had to suffer months of having to buy bottled water because of Cryptosporidium in their water supply for a large part of 2007. Several people became ill because of the poor water quality and tourism was badly affected. The bad news is that it could get worse for many other Irish towns.The following towns are some of the larger ones in Ireland where drinking water supplies have been identified by the Environmental Protection agency as needing improvements because thay have inadequate treatment for Cryptosporidium. (Over 184 thousand people are supplied by these sub standard water schemes).
