| Abstract | The Institute for Reference Materials and Measurements (IRMM) of the Joint Research Centre (JRC), a Directorate-General of the European Commission, operates the International Measurement Evaluation Programme (IMEP). IMEP organises interlaboratory comparisons (ILC's) in support to EU policies. This ILC exercise reports the performance of the laboratories on the determination of bromate in drinking water in support to the Council Directive 98/83/EC (Drinking Water Directive, DWD). Seven test materials were included in this study: soft drinking water, hard drinking water, mineral water, swimming pool water, raw water (untreated), a bromate standard solution and a blank solution consisting of non-spiked ultra pure water. The bottles containing the blank solution were labelled as river water. The 25 participating laboratories were invited via the IRMM website and the European Co-operation for Accreditation. z scores were calculated with a target standard deviation of 25 % of the reference value. The scores were satisfactory for a high share of the participants (75 % for soft drinking water, 90 % for hard drinking water, 73 % for mineral water, 100 % for swimming pool water, 86 % for raw water and bromate standard solution, respectively). In addition, zeta scores were calculated for participants having reported a measurement uncertainty. These were however, less satisfactory on average. In summary, the measurement capabilities of laboratories involved in the determination of bromate measurements in the frame of the DWD is satisfactory considering that the concentration levels in almost all matrices were lower or equal to the maximum permitted level of bromate in these types of matrices.

The mission of the JRC is to provide customer-driven scientific and technical support for the conception, development, implementation and monitoring of EU policies. As a service of the European Commission, the JRC functions as a reference centre of science and technology for the Union. Close to the policy-making process, it serves the common interest of the Member States, while being independent of special interests, whether private or national. LA -N A -2436-EN -C |
