Concerns about a potential sewage leak at a popular UK beach have been dismissed after authorities confirmed that the murky brown water was caused by a harmless algal bloom. Natural Resources Wales (NRW) investigated reports of discolouration at Porthdinllaen beach in Gwynedd, where swimmers had expressed alarm over the Bank Holiday weekend.
Algae, Not Pollution
Arfon Hughes, environment team leader for NRW, stated: "Our officers received reports of potential pollution at Porthdinllaen beach over the Bank Holiday weekend. Upon inspection, this was found to be a type of non-toxic algae called Phaeocystis – one of the most common bloom-forming algae in our coastal waters. The blooms can form a brown, frothy scum that is harmless and may be influenced by recent sunlight and warmer temperatures."
NRW urged anyone with concerns about potential pollution to contact them via their 24/7 incident communication line on 0300 065 3000 or through their online incident form.
Porthdinllaen: A Stunning Beach
Porthdinllaen, located on a remote point of the Welsh coast overlooking the Irish Sea, boasts a sweeping sandy bay nestled behind a headland. It is renowned for its iconic seaside pub, Ty Coch, which has earned a place among the finest beach bars in the world. Like many beaches across the UK, it was exceptionally busy over the Bank Holiday weekend, during which temperatures exceeded 34°C in parts of the country.
The warmest places on Tuesday were confirmed as Heathrow Airport and Kew Gardens in west and southwest London respectively. However, the weather is set to change, with thunderstorms forecast for parts of the Midlands, Home Counties, and northern England. The Met Office warned: "There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds."
Separate Sewage Issues Elsewhere
Meanwhile, residents in Plymouth have been enduring a "horrible smell" due to pollution following a spill at a nearby sewage overflow. Locals claim the stench is worsening, with one event last month described as "absolutely disgusting." Some families in the Devon city have been forced to keep their windows firmly shut to escape the odour.
