Letterkenny is the cleanest town in Ulster.
That's according to the results of teh 2010 survey commisioned by Irish Business Against Litter (Ibal) published this morning.
Of 53 twons surveyed, just over half recieved the accolade "litter - free" - down from two-thirds on last year.
Letterkenny was found to be the cleanest town in Ulster, Sligo the cleanest in Connacht, while Killarney was the cleanest in Munster.
Irelands cleanest town was Wexford, which had "consistently high standards of maintenance of the environment".
The distinction of worst performing town was Tallaght. The Dublin suburb was dubbed a "litter blackspot" which was showing "signs of overall neglect, a big challenge which must be surmounted".
Naas in County Kildare and Midletown in County Cork also fared badly, both judged to be "seriously littered".
Limerick last year described as a "litter black-spot", improved this year to merely "littered" but it was referred to as "again the most littered" of cities
