  • bathing water description
    Perranuthnoe is on the south coast of Cornwall. It is a rural sandy beach, approximately 350 metres wide, backed by cliffs.
  • controller name

  • eso outfalls statement
    This bathing water is included in the Surfers Against Sewage “Safer Seas Service”. This service can alert you to Combined Storm Sewer Overflow discharges via a phone App and in addition, it includes the Environment Agency Pollution Risk Forecast warnings where they are available. Further details of the service can be found at - http://www.sas.org.uk/safer-seas-service/
  • history statement
    The South West Water scheme for Perranuthnoe sewage treatment works (STW) was completed in June 1999, with the untreated sewage discharge at Maen-du Point retained as a combined sewer overflow and pumping station emergency overflow. Sewage from Perranuthnoe is pumped to the Hayle STW, where it receives secondary treatment and discharges through a 2.7 kilometre (km) long sea outfall west of Godrevy Head in St Ives Bay. The STW at Hayle was enlarged and upgraded in 1995 to take the additional flow.
  • 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 7% 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, but that it can be noticeable from time to time.
  • phytoplankton statement
    For the four year (2020-2023) assessment period where data is available, phytoplankton (microscopic algae) was not noted at this site. 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.

  • 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 Perranuthnoe 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 22% of visits. Tarry residue was not noted at this site.
  • zoi description
    The catchment surrounding Perranuthnoe is approximately 83 hectares and includes the small village of Perranuthnoe and surrounding hamlets. There are no streams discharging directly to the beach. Surface water drains to the beach from the catchment. The catchment is in the Cornwall Area of Outstanding Natural Beauty (AONB).

    • 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.
