AB  - 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.
