Bathing Water Quality Information

People visiting a beach will want to use the water for a variety of activities and want to do this in the knowledge that it will not have a bad impact on their health.

In England the Bathing Water Directive is administered by the Department for Environment, Food and Rural Affairs (DEFRA) and is implemented by the Environment Agency (EA). On beaches that have been designated as bathing waters, the EA are guided by the Bathing Waters Directive, which has been made stricter, setting out tighter water quality standards to protect beach users throughout the bathing season. Not all beaches are designated as bathing waters, in Cornwall there are 82 beaches that are.

The bathing water season extends from mid-May to the end of September, throughout this period the EA sample bathing water quality on a weekly basis. This process helps classify the quality of the bathing water associated with the beach. The responsibility for displaying public information at a bathing water lies with its 'bathing controller' which on many of the beaches in Cornwall is Cornwall Council. 

A number of designated bathing waters in Cornwall receive bathing water notifications, which identify when an event has occurred that could potentially impact on bathing water quality. When a notification is issued Cornwall Council work with South West Water (SWW), the EA and local bathing water champions to put notifications on the beach. The purpose of this is to give beach users an informed choice about when and where to bathe.

There are three different types of notification.

SWW have developed a system called BeachLive, which notifies the Council and informs the public should a Combined Sewer Overflow (CSO) discharge. This gives an indication that sewage related waste could be entering onto the bathing water. CSO’s generally discharge during heavy rainfall events and a notification is triggered once a CSO discharges. Please note that not all beaches are affected by CSO's and some sites that are do not have a notification system.

The EA run a Pollution Risk Forecasting (PRF) system that provides notifications based on predicted rainfall and its correlation with lower water quality. The system warns when there is an increased risk of reduced water quality. As the name suggests this is a forecasting system and an update is provided daily on the EA website throughout the bathing water season. Please note that the EA do not provide PRF notifications on all designated bathing waters.  You can view bathing water quality across Cornwall online via the Environment Agency website.

The final type of notification is associated with Abnormal Pollution Events, which may affect a beach. As the name suggests these events tend to be more unusual and not associated with CSO or PRF notifications.
