Should you take the plunge? How to tell how clean the sea is

In Devon and Cornwall, swimmers can check beach water quality through official ratings, apps, and flags that indicate bacterial levels and potential risks. Factors like sewage spills, rain, and pollution influence water safety, but testing occurs only during the bathing season and at designated sites. A new app provides real-time alerts about sewage discharges and other pollution, helping swimmers make informed decisions about when and where to swim. These tools aim to improve transparency and safety for beachgoers.
