  • bathing water description
    Constantine Bay is on the north coast of Cornwall. It is a rural sandy beach, approximately 660 metres wide, backed by sand dunes and edge by rocky outcrops. There are several rock pools exposed at low tide.

  • macro algae statement
    For the four year (2020-2023) assessment period where data is available, seaweed (macroalgae) was assessed as being sufficient to be objectionable for 4% of visits, with 68% of visits noting the presence of seaweed (macroalgae). The bathing water can become covered with large amounts of seaweed, depending on tides and the weather. This bathing water does not have a history of large amounts of seaweed, although it can be noticeable at times.
  • phytoplankton statement
    For the four year (2020-2023) assessment period where data is available, phytoplankton (microscopic algae) was not assessed as being sufficient to be objectionable, but was observed as being present on 4% of visits. Phytoplankton (microscopic algae) naturally increase in number at certain times of the year. This process is known as a phytoplankton bloom. This bathing water does not have a history of phytoplankton blooms. The risks to human health from contact, ingestion or inhalation with marine algae that currently occur in UK coastal waters are considered to be low. However, some individuals may be more sensitive and display some reactions. A common marine algae found in UK coastal waters is Phaeocystis, which is often mistaken for sewage as it forms foam and a brown scum, but it is non-toxic.
  • pollution risk forecast statement
    There are no active pollution risk forecasts made at this bathing water. However any bathing water has the potential to be affected by a pollution incident and if this occurs a pollution risk warning with associated advice against bathing will be issued on this website.

  • streams rivers statement
    Streams and rivers are typically affected by human sewage, animal slurry and runoff from roads. There is a very small stream flowing onto this beach which can affect water quality after heavy rainfall.

  • visible pollution statement
    Environment Agency samplers make observations of litter present on the beach at every visit, this includes assessments of sewage debris, litter and tar. At Constantine Bay for the four year (2020-2023) assessment period where data is available, sewage debris was not noted at this site. Litter was not assessed as being sufficient to be objectionable, but was observed as being present on 36% of visits. Tarry residue was not noted at this site.
  • zoi description
    The catchment surrounding Constantine Bay is approximately 250 hectares. The stream that enters the sea at the beach is approximately two and a half kilometres (km) long. It flows through the small rural settlement of Constantine Bay before disappearing into the sand at the beach. This is not a very steep catchment and there is an area of flat dunes behind the bay which includes a golf course. This area and much of the lower part of the catchment is designated as Trevose Head and Constantine Bay Site of Special Scientific Interest (SSSI). The catchment is within the Cornwall Area of Outstanding Natural Beauty (AONB). Land use is split between improved grassland and arable, and also includes the urban areas of Constantine Bay and St Merryn.

    • 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 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 role to drive improvement of water quality at bathing waters that are at risk of failing higher 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 since the 1980s.
