Blackpool North and Blackpool Central had also faced blacklist, in part due to droppings from donkeys doing tourist rides.
Donkey owners were urged to clean up after the animals to avoid the faeces being left on the sand and washed out to sea.
But the local council said that the main issues, involving sewage, had been eradicated because United Utilities had invested £160million worth of infrastructure improvements.
Agriculture was cited as the main pollutant at several beaches often due to effluent from livestock grazing near streams that feed into the sea, and new cattle fencing was installed to tackle the problem.
Many other beaches had problems from sewage treatment works or sewage overflows.
