The quality of the bathing water

The coastline of the Destination Bretagne Plein Sud is rich in beaches of all shapes and sizes.  From tiny rocky coves to long sandy beaches there are in fact 40 bathing sites which are registered with the ARS (Agences Régionales de Santé – formerly known as DDASS = regional public health and safety organisation) including the fresh water bathing site at Saint-Lyphard.

The monitoring of the quality of bathing waters

The regular monitoring of the quality of the bathing waters of these 39 beaches is coordinated by the ARS from June to September.  The results of these analyses are posted up at the relevant beaches and can be consulted at any time.  They are also available online on the website of the Ministry of Health.

Operation ‘Quali-bain’

Since the summer season of 2011, Cap Atlantique in partnership with the towns/villages and the ARS have made available information panels at all the beaches which are referenced.  This operation code named ‘Quali-bain’ has as a main objective to inform the general public about the quality of the bathing waters throughout the summer.

For a better understanding of the phenomena of so called ‘coloured water’ and useful information about jellyfish

The sea water does on occasions take on a strange appearance: it can be coloured red, green or brown (so called ‘eaux colorées’ = coloured waters).  There may also sometimes be an abundance of foam and/or even mass mortality amongst the marine organisms.  These phenomena, visible to the naked eye, are due to an exceptionally high proliferation of micro-algae.
