A model tool for bathing water quality management: A case study on Salmonella occurrence at the southern Baltic coast

Abstract. Combined sewer overflows (CSOs) affect bathing water quality of receiving water bodies by bacterial pollution. The aim of this study is to assess the health hazard of bathing waters affected by CSOs. This is useful for bathing water managers, for risk assessment purposes, and for further impact and economic assessments. Pollutant hazard was evaluated based on two novel indicators proposed in this study: the mean duration of insufficient bathing water quality (1) over a period of time (i.e., several years) and (2) after single CSO/rain events. In particular, a novel correlation between the duration of seawater pollution and the event rainfall volume was developed. Pollutant hazard was assessed through a coupled urban drainage and seawater quality model that was developed, calibrated and validated based on local observations. Furthermore, hazard assessment was based on a novel statistical analysis of continuous simulations over a 9-year period using the coupled model. Finally, a validation of the estimated hazard is also shown. The health hazard was evaluated for the case study of Badalona (Spain) even though the methodology presented can be considered generally applicable to other urban areas and related receiving bathing water bodies. The case study presented is part of the EU-funded H2020 project BINGO (Bringing INnovation to OnGOing water management – a better future under climate change).

Bathing Water Quality

A contingent valuation (CV) study was undertaken to investigate individuals' stated willingness to pay (WTP) to reduce perceived risks of illness from the quality of bathing water at two beaches in East Anglia, United Kingdom. One beach, Great Yarmouth, failed to meet the EC (European Community) Bathing Water Quality Directive standard, whereas the other at Lowestoft passed. The analysis focuses on determinants of individuals' WTP, including measures of risk perception and attitudes to health not usually measured in CV studies. A conceptual model is then presented which sets the valuation of individual preferences in the context of personal worldviews, and external cultural, societal, and environmental factors which may influence, directly or indirectly, an individual's stated WTP.
