bathing water description |
The 170 metre cove slopes gently and comprises of sand, backed by steep cliffs on
the west to Nell's Point, with a harbour wall on the east. It faces south east towards
the Bristol Channel and is backed by the highly urbanised town of Barry. The water
quality sample point is located at the centre of the bay.

eso outfalls statement |
Within the catchment of Jackson’s Bay bathing water, there are numerous storm, emergency
and surface water outfalls that discharge into the River Cadoxton and the harbour.
These protect domestic properties in Barry from being flooded by sewage during heavy
rainfall. However, sewer overflows operating during and following periods of heavy
rain can result in a deterioration in the quality of bathing water at Jackson’s Bay.
In recent years, screens and telemetry equipment have been installed in most overflows
and pumping stations by Dŵr Cymru Welsh Water. The use of telemetry systems allows
Dŵr Cymru Welsh Water to respond to warnings of blockages in the sewerage system,
reducing the number of actual and potential overflows.

history statement |
Dŵr Cymru Welsh Water has invested a significant amount of money to upgrade the sewerage
infrastructure in the Barry catchment, under the Asset Management Programme. The five
year rolling programmes are developed by Natural Resources Wales and Dŵrr Cymru Welsh
Water to bring about water quality improvements and comply with environmental legislation
and European directives.
In 2009, an ultra violet disinfection treatment plant was installed at Cog Moors Sewage
Treatment Works to disinfect storm discharges from this site. It is believed these
upgrades will improve bathing water quality in the area.
Natural Resources Wales will continue to work with Dŵr Cymru Welsh Water to make further
improvements to the sewerage system, where necessary.

investigations statement |
Natural Resources Wales is continuing to work with the Vale of Glamorgan and Dŵr Cymru
Welsh Water to establish sources of pollution that are adversely impacting the water
quality around Jackson’s Bay.
Inspections are carried out by Natural Resources Wales in partnership with the Local
Authority. These are carried out pre-season (before the 1st of May) and mid season
if required (during the bathing water season).
The program of investigations to identify the sources of bacteria that impact on bathing
water quality at Jackson’s Bay from the River Cadoxton’s catchment is continuing,
with issues such as small housing estate misconnections being identified and resolved.

local authority statement |
Natural Resources Wales and the Vale of Glamorgan Council have been working together
to improve the bathing water quality at Jackson’s Bay for a number of years. Information
is being shared to develop a combined approach to resolving issues impacting the water
environment.

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

misconnections statement |
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. These algal blooms can occur
at any beach during the bathing season and are usually noticeable by a surface scum.
This beach does not have a history of such blooms.

stw outfalls statement |
Cog Moors Sewage Treatment works, serving the Barry and Cardiff West catchments, discharge
to the Bristol Channel, via a long sea outfall, off Lavernock Point, to the east of
Jackson’s Bay. Disinfection through ultra violet treatment of the storm effluent further
reduces the environmental impact from the treatment works and protects the bathing
water quality.

zoi description |
The natural drainage (hydrological) catchment surrounding the bathing water is highly
urbanised with commercial buildings in the immediate vicinity. The River Cadoxton
meets the sea 1 km east of the Bay. This may also influence bathing water quality,
depending on tidal currents and weather conditions. The River Cadoxton drains a large
and diverse catchment. In the lower reaches, there is a combination of large residential
areas and heavy industry, along with several small industrial estates. Towards the
top of the catchment, the land is largely rural, which is not intensively farmed.

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.

Discharges from sewage treatment works have improved substantially in England and
Wales since the 1980s.
