bathing water description |
Measuring approximately 350 metres, facing north into the Irish Sea, Cemaes is an
enclosed sandy bay, backed by a promenade. There is a concrete jetty in the southwest
corner of the bay, which provides a small harbour for leisure craft and some inshore
fishing vessels. The water quality sample point is located opposite the car park,
approximately 50 metres east of the harbour. The beach lies within the Anglesey Area
of Outstanding Natural Beauty and part of the beach is within the North Anglesey Heritage
Coast.

eso outfalls statement |
Within the Wygyr catchment, there is one intermittent discharge from Llanfechell Sewage
Pumping Station. After periods of rainfall, this discharge could have an adverse affect
on bathing water quality. There is a pumping station at Cemaes Bay, which also discharges
under storm or emergency conditions, however this effluent is discharged directly
to coastal waters.

history statement |
Natural Resources Wales has developed a good working relationship with Dŵr Cymru Welsh
Water and liaises regularly to identify problems that could affect bathing water quality.
Natural Resources Wales is working with Dŵr Cymru Welsh Water to trial a programme
of disinfection at Llanfechell Sewage Treatment Works. This is part of a long term
initiative to reduce levels of bacteria entering the Wygyr and ultimately the bathing
waters.

investigations statement |
Natural Resources Wales works to establish sources of pollution around Cemaes Bay.
Some of this work is carried out in partnership with Anglesey County Council and Dŵr
Cymru Welsh Water. 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). Natural
Resources Wales has carried out a DNA analysis in the upper reaches of the catchment
to analyse which areas have high levels of bacteria. The results help to target pollution
prevention work in areas of high bacterial contamination that could affect water quality.
The Elimbac trial is continuing with higher dosages to kill off viruses

local authority statement |
Natural Resources Wales has been working with Anglesey Council to deal with the septic
tank serving the toilet block at the beach. A temporary fix is in place. A connection
to sewer is being considered.

macro algae statement |
This bathing water does not have a history of large amounts of seaweed (macroalgae). |

misconnections statement |
Wrongly connected waste water pipes can affect the water quality of rivers and the
sea. Natural Resources Wales is working with home owners on a housing estate in Llanfechell
to resolve misconnections which are contaminating surface water entering the river.
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.

zoi description |
The natural drainage (hydrological) catchment immediately surrounding the bathing
water is initially urban, being the town of Cemaes Bay, then further into the catchment
the land becomes rural. The majority of the catchment is dominated by agriculture,
and drained by the River Wygyr, which discharges onto the bathing beach.

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 England and 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 the Environment Agency and 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.

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