§ Mr. Simon HughesTo ask the Secretary of State for the Environment what analysis has been carried out to establish levels of dissolved radon in drinking water; and if he will make a statement.
§ Mr. Heathcoat-AmoryRadon in water results from the structure of the ground from which the supply emanates. It is believed to be confined to a few areas. Where radon is likely to be present in a water source, a specific analysis is carried out and the water company may treat the water to remove it, seeking advice on levels from the National Radiological Protection Board. No standard is set for radon in the EC drinking water directive or the Water Supply (Water Quality) Regulations which incorporate the provisions of the directive. We are currently reviewing the matter of radiological standards.
