A statement from the council on Thursday urged people not to use the pond while the issue is being addressed. Animals should also be prevented from using it, while recreational activities such as fishing should also not be done at this time.
Residents are advised to ensure pets, particularly dogs, do not enter the water of the pond. Should pets come in contact with the water, owners are advised to thoroughly wash the animal with clean water and seek precautionary advice from a qualified vet.
Cllr Nigel George, Cabinet Member for Environment and Neighbourhood Services, said: "This advice certainly isn’t intended to cause undue concern and worry however it is important that no recreational activities, including fishing or public access takes place and that residents and visitors are aware that animals should not be allowed to enter the water of Pen y Fan Pond.
"Signage has been placed around the pond and regular inspections of the body of water will continue to take place. "We will continue to work alongside Natural Resources Wales to address this issue."
