Project Abstract
As CSO discharges contain raw sewage and a range of dissolved and particulate contaminants including heavy metals, PAHs, oils &grease, along with large volumes of storm water, they can create significant public health and water quality concerns. It has been recognised as a potential cause of receiving water impairments, and contributed to beach closures, shellfish bed closures, contamination of drinking water supplies, and other environmental and public health concerns worldwide. In early August 2014, 12 beaches in Dublin were closed due to health concerns over water pollution by CSOs discharges. Therefore, in order to protect water bodies in Ireland, characterising and treatment of the CSO discharges are urgently needed. However, there is lack of detailed information about CSO discharges, and comprehensive research carried out to assess the risk of CSO discharges on receiving water quality is scarce in Ireland. In this proposed project, technologies for monitoring, detecting and treating CSO discharges will be reviewed and assessed in Irish context, and a decision support tool for determining the level of monitoring required of a CSO will also be developed. � Literature reviews on monitoring and treatment of CSO discharges � A decision support tool which determines the level of monitoring required for a CSO in Ireland; � Final report and 2-page summary report; � One publication each in the areas of monitoring technologies and CSO retrofits in highly-ranked journals such as Water Science and Technology and Environmental Monitoring Technology; � Project website for updates, and public engagement.
