The SWIM project will enable short-term pollution to be predicted, through the development of a bathing water quality prediction model and deriving from this, the capacity to inform the public through a series of media channels including text alerts and automatic web updates, and real-time communication via alert services delivered through electronic signage installed strategically at beach entrances. This will help to protect public health, significantly improve communication to members of the public, and in doing so contribute to promoting tourism.Achieving and maintaining high marine water quality standards is required under stringent EU environmental legislations (e.g., Bathing Water Directive (2006/7/EC), Shellfish Waters Directive (2006/113/EC), and Water Framework Directive (2000/60/EC). To ensure effective and efficient implementation of these directives, water resource managers need to know the water quality in order to take appropriate mitigating actions for social and ecological benefits in the event of pollution. This is particularly so for the Bathing Water Directive, where water quality is defined in terms of Escherichia coli and intestinal enterococci (IE) concentrations as percentile limit values. Predictive capability and public communication outcomes of the project will help to serve the needs of both the Competent and the Health Authorities in the cross-border territory, with consequent benefit to local and visiting bathing water users. As evidenced by supportive correspondence, ROI (Republic of Ireland) and NI (Northern ireland) Local Authorities have committed to involvement in the project because the outcomes gained will be valuable to them.
