Question:118 Mr. Durkan asked the Minister for the Environment if he has any plans to control aluminium levels of public water supplies; and if he will make a statement on the matter.
Written Answers. - Aluminium Level in Drinking Water.
The maximum admissible concentration for aluminium specified in the European Communities (Quality of Water Intended for Human Consumption) Regulations, 1988, is 0.2 mg/1. Reports on the Quality of Drinking Water in Ireland (1989), compiled by the Environmental Research Unit and published by me on 17 October 1991, identified aluminium in excess of this concentration as a significant problem in drinking water. Counter-measures to deal with this problem are a priority in the programme of capital works for water supply. Extension or replacement of treatment works and distribution systems, where necessary, is being supported by the investment commitment of £300 million in the environment action programme.
I have also asked sanitary authorities to review all aspects of the management and operation of water supplies. The indications are that, in many cases, better treatment works practice and more active supervision would bring the drinking water quality into conformity with the regulations.
