bathing water description |
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.

The emergency/storm discharge from the nearest village, Newborough, also discharges
into the Braint, under consent conditions.

|
|
investigations statement |
Inspections are carried out by Natural Resources Wales in partnership with the local
authority and the water company. These are carried out pre-season (before the 1st
of May) and mid season, if required (during the bathing water season).
|
|
|
local authority statement |
Natural Resources Wales liaises regularly with the council with regards to the bathing
waters during the bathing water season.

|
macro algae statement |
This bathing water does not have a history of large amounts of seaweed (macroalgae). |
|
|
misconnections statement |
There are no known misconnections in this catchment.
Modern sewerage systems have two separate systems, one takes foul sewage to sewage
treatment, the other takes rainwater runoff through surface water drains to rivers,
lakes and the sea. Misconnections occur when waste water pipes are plumbed into surface
water drains instead of the foul water sewerage system. This can give rise to pollution
when the waste water is discharged directly to the environment through the surface
water drain. For example, a washing machine or toilet may be incorrectly plumbed so
that it discharges to the surface drain rather than the foul sewage drain.

|
|
phytoplankton statement |
Phytoplankton (microscopic algae) naturally increase in number at certain times of
the year. This process is known as a phytoplankton bloom.
Algal Blooms can occur at any beach during the bathing season and are usually noticeable
by a surface scum. This beach has no history of such blooms.

The sewage works from the nearest village, Newborough, discharges its treated effluent
into the River Braint, well away from the bathing water.

visible pollution statement |
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.

zoi description |
The natural drainage (hydrological) catchment surrounding the bathing water is forested
land and sand dunes. There are no direct surface or foul discharges to the beach,
only run off from the surrounding forest.

algae general statement |
Seaweed (macroalgae) and phytoplankton (microscopic algae) are a natural part of the
marine and freshwater environment. Below we note whether these have been recorded
in quantities sufficient to be a nuisance.
|
|
|
eso outfalls general statement |
The majority of sewers in Wales are “combined sewers” and carry both sewage and surface
water from roofs and drains. A storm overflow operates during heavy rainfall when
the sewerage system becomes overwhelmed by the amount of surface water. The overflow
prevents sewage from backing up pipes and flooding properties and gardens. An emergency
overflow will only operate infrequently, for example due to pump failure or blockage
in the sewerage system.
|
|
|
local authority general statement |
Heavy rain falling on pavements and roads often flows into surface water drains or
highway drains, ending up in local rivers and, ultimately, the sea. The quality of
bathing water may be adversely affected as a result of such events.
|
|
|
pollution management general statement |
It is Natural Resources Wales' role to drive improvement of water quality at bathing
waters that are at risk of failing European standards. It is natural for water to
run off the land to the sea. Water quality at a bathing water is dependent upon the
type and area of land (the catchment) draining to the water and the activities undertaken
in that catchment. The following sections serve to highlight potential sources of
pollution, conditions under which they may arise and measures being put in place to
improve water quality.

|
stw outfalls general statement |
Discharges from sewage treatment works have improved substantially in Wales since
the 1980s.
