Kerry County Council says it`s now safe for people in the Ballyheigue to Kerry Head area to use their water straight from the tap. For over a week up to 4000 households were affected by contaminated water in the district from Ballyheigue to Kerry Head. Residents were advised to boil water because an indicator of pollution was found. Preliminary investigations are underway as to what the pollutant is. Vincent Horgan is senior engineer with the Water Services Department.
