Natural Resources Wales (NRW) has moved to reassure local people and visitors that Welsh beaches are “clean and healthy” despite a frothy scum washing up on along the coastline. ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

NRW officers say they have received a “few reports” from people concerned about what they believe is sewage or slurry on beaches or in the water around the coast in Wales. ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

The reports have been investigated, NRW has said 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 typically brown, frothy appearance and its slight seaweed like smell. NRW sayd. ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

As the algae die off, scum may start to form along the tide line. ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

While these scums may be unpleasant to look at and may smell bad, they are not a health hazard to swimmers or dogs. ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

Fiona Hourahine, Operations Manager, Natural Resources Wales said: ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

“We have fantastic beaches in Wales and really great water quality with more than 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.” ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​

People can report any sightings on the Natural Resources Wales incident hotline: 0300 065 3000  or online Natural Resources Wales / Report an incident. ‌​‌‌‌​‌‌‍‌​‌‌‌​‌​‍‌​‌‌‌​‌​
