Drinking water disinfection can be done with chlorination, ozonation or UV-irradiation. However, only chlorination has residual disinfection effects in drinking water distributions system.

The objective for risk-benefit analyses (WP8) is to create a model of microbial contamination of drinking water versus chemical risk and to conduct risk-benefit analyses including quantitative assessments of risk associated with microbial contamination of drinking water versus chemical risk, compare alternative treatment options, and produce burden of disease risk estimates.

One of the main objectives of the project is also to review the water and health policies in Europe, USA and worldwide in relation to water disinfection linked to food industry, including best practice in terms of water disinfection and a brief assessment of alternatives (WP9 and WP10). A final workshop organised as an open conference with the aim to bring together scientists working on environmental, toxicological, epidemiological and policy aspects of DBPs, microbiologists, policy makers, and representatives from the water industry together with consumer organisations in Europe will develop guidelines for policy across Europe and the future research agenda.
