Beach Water Quality

Bathing Waters at beaches are sampled and tested by the Environment Agency. They have published draft Bathing Water Profiles for all our bathing beaches. For more information on beaches, visit the Environment Agency website.

Bathing water quality is measured by the amount of bacteria within a water sample. Counts are undertaken throughout the bathing season to see if the water quality meets the EC's Bathing Water Directive. The Directive sets limits for a number of substances, and all countries in the European Union have to ensure their popular beaches meet these standards. These popular beaches are known as Designated Bathing Waters.

What are Coliforms?
The Coliform group of bacteria are the most important of the Directive standards tested for. In general these can be taken as an indication of sewage contamination present.

How is water quality assessed over a bathing season?
Bathing waters must be tested at weekly intervals between May 1st and 30th September, with a minimum of 20 samples tested. There are two measurement criteria - a mandatory standard, which must be met in order for a bathing area to pass and a guideline standard, which member states should strive to achieve.

Mandatory:
Over a bathing season 95% of samples taken must be equal to or better than the main Mandatory standards of less than 10,000 total coliform bacteria and no more than 2,000 faecal coliforms per 100ml

Guidelines:
Over a bathing season 80% of samples must be equal to or better than the stringent Guideline standards of less than 500 total coliforms and 100 faecal coliforms per 100 ml, and 90% of samples equal to or better than the faecal streptococci standard of 100 per 100ml.

Beach Awards
Blue Flag
The Blue Flag is an exclusive eco-label awarded to approximately 3400 beaches and marinas in 44 countries across Europe and South Africa each year.
The Blue Flag Campaign is owned and run by the independent non-profit organisation Foundation for Environmental Education (FEE). The Blue Flag works towards sustainable development at beaches/marinas through strict criteria dealing with water quality, environmental education and information, environmental management, and safety and other services.
The Blue Flag Campaign includes environmental education and information for the public, decision makers and tourism operators.
