Abstract

A challenge describes both opportunities and barriers, and an enabler provides means to manage achallenge. The framework for the deliverable is based upon identifying process facilitators (e.g.workshops) and discursive abilities/devices providing enablers that partners used in order to make senseacross organizations and professional communities (developers and users) as a means to develop anddeploy digital technologies and services. IVL lead the work and edited the deliverable. Gothenburg city (CGEA), city of Amersfoort (COA) andBarcelona waste and wastewater company (BCASA) provided experiences as stakeholder and dataprovider, through user involvement. IVL Swedish Environmental Institute, Eurecat (EUT), Talkpool (TP),Civity (CIV) provided experiences from development and implementation work (focusing on stakeholderengagement and user involvement). They all contributed to the deliverable through meetings and writingone section each. Analysing the same processes from different points of view provided interesting insightsinto the development process and implications for the coming phases of the project. The Gothenburg section expresses how insights from cooperation issues from before the project, wereturned into a well-designed collaboration process (process facilitator) between developers andusers/stakeholders. In Gothenburg, engaging with various departments within the municipality and withexternal stakeholders has been a continuing learning process for IVL (case study leader). IVL graduallypresented various opportunities within the project, both in Amersfoort and Barcelona, which has beenvery much appreciated by the stakeholders. In this way, the engagement process has also enabledstakeholders to envision a number of opportunities that the new technologies empower that can becontinued beyond SCOREwater. Moreover, due to a fruitful collaboration between developers and stakeholders, both Gothenburg andBarcelona cities now envision even more opportunities and ambition

Abstract

Rapid population growth and coastal development has led to increased fecal contamination of coastal surface waters worldwide, enhancing the potential risk of waterborne human pathogens in bathing areas. More frequent heavy rainfall events, attributed to global warming, have further exacerbated the problem by causing sometimes sewer overflows into recreational waters. As traditional bacterial indicators have limited accuracy for predicting health risks associated with waterborne viruses, the additional use of viral indicators such as coliphages is recommended. In this study, we compared the behavior of bacterial and viral indicators of water quality at 10 Barcelona beaches during three bathing seasons, in dry conditions, and after four rainstorms that caused specific pollution events due to rain runoff with combined sewer overflows (CSO). Levels of all target indicators increased after the rainstorms, but compared to Escherichia coli and intestinal enterococci, somatic coliphages exhibited a slower decline and higher environmental persistence following a rain event. Daily continuous sampling carried out during the days following a rainstorm allowed not only the determination of the decay kinetics of each target indicator but also the day when the water quality recovered the values established in the current European regulation in approximately 2 -3 days after each CSO. These observations indicate that the combined use of bacterial and viral indicators can enhance the surveillance of microbial quality of bathing waters. Moreover, coliphages can swiftly provide insights into transient fecal pollution linked to rainfall episodes, thanks to available analytical techniques that enable same-day recommendations. The management of urban wastewater and recreational water regulations should consistently employ microbial indicators to address rainwater runoff or sewer overflows resulting from heavy rainfall., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).
