The Taoiseach Bertie Ahern has told the Dáil that Galway City Council had been given €21m to deal with a new water scheme but that they could not agree on how to spend it.
Mr Ahern said he was not going to get involved in local Galway politics but that the money had been allocated and was not spent.
He said that the water supply from Tuam would be increased to augment the city water supply and that the old water treatment plant would be phased out.
He added that the Tuam system would deliver more supply from the summer onwards.
In response, Fine Gael leader Enda Kenny claimed that the level of pollution in Lough Corrib was a national scandal.
He hit out at Environment Minister Dick Roche for what he called his juvenile and irresponsible performance on dealing with the problem which he had 'hived' off.
He said the people of Galway were now taking daily cryptosporidium showers and felt disgusted by this.
