The project relates to Theme III.1 (human health) and III.2 (water monitoring). Indeed the World Health Organisation has classified bromate in Group 2B, i.e. 'Possibly carcinogenics to humans'. Therefore as the occurrence of bromate represent a risk for public health, there is an urgent need for rapid and sensitive methodology to analyse bromate in drinking water. As a result, both public health utilities and water utilities need to have in place accurate and repeatable laboratory based method to determine bromide at a ug 1{-1} level. At the end of the project, a reference method will be made at the disposal of CEN TC 230 (Water Analysis). Dissemination of results achieved within the project and transfer of experience will allow a greater number of European analytical laboratories to determine easily bromate concentrations in distributed drinking waters, with a good accuracy. Confirmation methods for bromate determination will be available in the cases of drinking water difficult to analyse (mainly due to the presence of interferences). Moreover field-methods be available to monitor bromate on waterworks. The proposed project involves 8 partners (water suppliers and water research institutes.
