Assessment of effect of high level of disinfectants on products in contact with drinking water: Development of a harmonised test to be used in the European Acceptance Scheme concerning CPDW

Project ID: EVK1-CT-2000-00052
Funded under: FP5-EESD

Abstract

The objectives of this research were first to complete a review of the use of high levels of disinfectants applied to water distribution systems in Europe, then to obtain experimental data concerning the migration rate under different disinfection conditions for a range of the representative CPDW commonly used in Europe and finally to give guidance to the regulators about the need to include a simulation of high levels of disinfection in the European Acceptance Scheme (EAS).

This report covers the experimental part of the research, which included a testing programme: a range of organic products was preliminarily exposed to different disinfection procedures (chlorine and hydrogen peroxide under several contact times and concentrations) and the migration rate was compared with the same materials not exposed to disinfectants. The products to be studied were chosen taking into account their main uses in European water distribution systems application (PVC-U, HDPE, EPDM, epoxy and polyester resins, cement with organic additive).

The test results showed clearly that there was no significant difference attributable to the different disinfectant solutions and contact times, and no difference when the products were not in contact with disinfectants.
