I t said Scottish Water and Scottish Environment Protection Agency (Sepa) had been alerted to the incident.
S cottish Water said its waste water plant at near Ellon had been "overwhelmed" by a river during recent heavy rain.
A spokesman said: “A team is working today to clean up on the affected section of beach.
"The waste water treatment works has returned to normal operation – and the cause of the incident is being investigated in order to minimise the risk of recurrence.
“We would like to apologise for the concern caused and are doing all we can to minimise any lasting impact on the environment.”
