This beach is located at the south west tip of the Isle of Anglesey. Access is gained
via a large conifer plantation owned by Forest Enterprise. Offshore sandbanks fringe
the bathing area, which forms a relatively sheltered shallow lagoon. The bay is located
within the Newborough Warren and Llanddwyn Island National Nature Reserve. It is also
within the Anglesey Coast Salt marsh Special Area of Conservation, the Anglesey Area
of Outstanding Natural Beauty and the Newborough Warren - Ynys Llanddwyn Site of Special
Scientific Interest. The bathing water sample point is located 420 metres south west
of the main beach entrance.
Natural Resources Wales samplers make visual observations of the beach at every visit.
This includes assessments of sewage debris, animal faeces, litter and oil or tar.
At Llanddwyn, data are available for the four year assessment period from 2011-2014.
Sewage debris was observed in trace amounts on less than ten per cent of occasions.
Trace amounts of animal faeces were noted at the site on a minority of occasions.
Trace amounts of litter were observed at the bathing water the majority of the time.
Oil and tarry residues were not noted at this site.
Poorly maintained private sewage treatment facilities could be a source of pollution,
therefore the registration of all private sewage systems in Wales is required by 30
June 2012. The primary aim of this exercise is to provide increased protection for
the environment and sensitive features such as bathing water beaches. Where properties
are identified in the catchment that are not on mains sewerage, Natural Resources
Wales will endeavour to ensure registration has been made.
