§ Mr. AllenTo ask the Secretary of State for the Environment what is the average level of plumbosolvency of the water(a) in Nottingham and (b) nationwide; and if he will make a statement.
§ Mr. MoynihanAs there is no standard measure of plumbosolvency it is not possible to give a numerical answer. However, the water supply to the city of Nottingham is not considered to be aggressive to lead pipework.
Lead monitoring surveys by water undertakers between 1980 and 1985 identified 130 water supply zones serving some 5 million people where lead levels were of concern. Water treatment schemes have been completed in 66 zones. Schemes should be completed in the remaining zones by the end of 1989.
