What's tested here?

Why isn't this a designated bathing water?
High levels of bacteria in the water can indicate pollution from sewage treatment works or polluted rain water draining from the land.
Where does pollution comes from and how can you help?
Water quality can be reduced for up to 72 hours after heavy rain. Look out for temporary signs at the beach and on our website.
