NRW confirms seasonal algae on some Welsh beaches

Natural Resources Wales (NRW) is reassuring local people and visitors that Welsh beaches are clean and healthy, despite some appearances of a substance in the water and on the beaches.

Officers have received a few reports from people concerned about what they believe is sewage or slurry on the beach or in the water in parts of South and South West Wales.

These have been investigated and found to be caused by tiny, naturally occurring algae, that thrive in warm weather conditions.

The algae is often mistaken for sewage or other pollution because of its oily appearance and its slight seaweed like smell.

Fiona Hourahine, Operations Manager, Natural Resources Wales said:

“We have fantastic beaches in Wales and really great water quality with above 80% of bathing waters reaching the highest standards for cleanliness.

“At this time of year, we get some reports of possible pollution on the coast. We treat each one seriously and assess every report.

“Despite its unpleasant appearance, most of the reports we receive turn out to be this common algae.

“Warm weather provides the conditions for the algae to occur and it will disperse naturally over time.”
