Bathing Water Quality

Wet weather urban discharges are responsible for bathing water contamination. The proposal for a revised EU Directive concerning the quality of bathing water imposes significantly more stringent requirements for the management of bathing water quality, with particularly important repercussions on beaches subjected to short-term pollution incidents. The paper reviews the aspects from EU legislation most directly related to the problem of wet-weather discharges, placing special emphasis on the recent revision process of the Directive on bathing water quality, and evaluates the benefits of some potential solutions based on continuous modelling of a combined sewer system. Increasing the sewer system storage capacity or the STP hydraulic capacity may substantially reduce the untreated discharge volumes, but spill frequency reductions under 2 to 3 spill days per bathing season will hardly be achieved. Results show the severe strains that local rainfall patterns would place on compliance with the Commission's proposal for a revised Directive and highlight the importance of the changes introduced in the amended proposal recently approved by the Council, making it less prescriptive if adequate measures are adopted to prevent bathers' exposure to short-term pollution incidents.

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).

Water Quality Deterioration

New European Directive 2006/7/EC concerning the management of bathing water quality introduces the concept of ‘active management of bathing water sanitary quality’ which could lead to a temporary bathing prohibition in case of short term pollution. For the last three bathing seasons, Veolia has carried out in experimental mode this ‘active management’ concept at more than one hundred bathing sites with various characteristics. Results confirm the high level of microbiological pollution observed in sewer overflows during rainy periods, which is the main cause of bathing water quality deterioration. An on-line treatment solution has been successfully tested. This solution may be used in dense urban areas.

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.

Objective: Lake Van is one of the most important recreation areas of the region. Investigation of microbiological pollution of Lake Van is very important for public health. The aim of this study is to assess the microbiological pollution and determine water quality of the lakes Van and Erçek situated within Van Province, which are used for swimming and recreation to protect both human and environmental health. For this purpose, the presence of fecal coliform, total coliform and enterococci were investigated in samples taken from 29 different points of the lakes. Method: Between June and September 2015, 232 water samples were taken from predefined 29 points, every two weeks, and sent to the Public Health Laboratory of Van Province in 300-500 mL sterile plastic bottles in accordance with Bathing Water Quality Regulation (76/160 / EU: add-on clause 5. Membrane filtration method was used to analyze the samples for coliform bacilli and enterococci. Mandatory values according to bathing water quality regulation were taken as 2000 cfu/100 ml,10000 cfu/100 ml and 1000 cfu/100 ml for fecal coliform, total coliform and enterococcus, respectively. Results: In 196 (84%) of 232 water samples collected, no bacterial contamination was found, while 36 (16%) samples were found contaminated with fecal coliform, total coliform and Enterococcus species. At least one or more specimens of poor quality water were detected in 17 of 29 sampled beaches. Conclusion: It was envisaged to take precautions by restricting the use of the places where microbiological pollution was detected. In addition, regular analyzes are important for public health.
