§ Mr. Simon Hughes
To ask the Secretary of State for Health if he has identified any possible public health implications resulting from the use of epoxy resin to line water mains; and if he will make a statement.
§ Mr. Dorrell
The Department of Health Committee on the Medical Aspects of the Contamination of Air, Soil and Water has reviewed reports of laboratory and field tests to determine concentrations of leached chemicals and toxicological tests on the major components of one formulation of epoxy resin. They advised that the epoxy resin could be approved for relining water mains in situ. This was taken into account by the Department of the Environment's Committee on Chemicals and Materials of Construction for Use in Public Water Supplies and Swimming Pools, which approved this formulation of epoxy resin in March 1989 for use for in situ relining of water mains.
