We sample the following Non EC Identified Beaches and in addition, carry out a survey of beach litter at the time of sampling (Garber Survey):
Barkby Beach, Prestatyn
Ffrith Beach, Prestatyn
Splash Point, Rhyl
Gronant Dunes, Prestatyn
Bathing water from each of the above mentioned beaches is monitored between 1st May and the 30th September each year.
In order to achieve high quality coastal water around Wales, the "Green Sea Partnership" has been set up and is co-ordinated by the Wales Tourist Board. Other members include: Local Authorities, Water Companies, local environment groups, the Countryside Council for Wales, the Environment Agency and Industry.
Marine Algae
Marine algal (phytoplankton) blooms can occur in Liverpool Bay and associated coastlines, and can affect some beaches in North Wales. These are caused by increased marine algal growth, forming dense populations of algae at different times and places. They are a natural occurrence and can occur in the spring and early summer. Some of the species which have been observed include:
Phaeocystis - can bring ashore gelatinous material and in rougher weather / windy conditions can cause foam. The blooms are non-toxic, but can cause aesthetic problems such as an unpleasant cabbage type smell when the algae are dying.
Chaetoceros - which is a long chain algae with spines and spears. It is an irritant to fish gills, thereby affecting the fish and causes some fish deaths. It is non-toxic to humans.
Noctiluca - it is non-toxic, but can turn the sea bright red, light green, orange or black and be phosphorescent.
Further information can be obtained from the Environment Agency Marine, Biological & Chemical Consultants (MBCC) monitors and investigates these blooms along the North Western Coasts of England & Wales.
