We are in ongoing discussions with the HSE about lifting the boil water notice. A number of criteria have been identified. As Mr. Gleeson said, the plant has to stabilise and then we have to get some clear samples. The EPA has to be satisfied and then we have to ensure that any water at risk, which may not have received an adequate amount of treatment, has left the system.
