Four bathing areas in Ireland have been classified as having poor water quality, with one of those being in Kerry.
The Environmental Protection Agency's annual report shows 111 out of 148 were deemed excellent in 2020.
13 of 16 bathing areas monitored in Kerry are deemed excellent by the EPA.
In March, the council advised people not to swim at Cúas Crom beach near Cahersiveen for the whole summer due to water quality issues.
Mary Gurrie of the EPA says the South Kerry beach is one of four rated as poor.
The water quality at some beaches can be impacted when pollution, from wastewater and agriculture, gets washed in following heavy rainfall. Swimmers are encouraged to check www.beaches.ie for the most up to date water quality information. Local authorities and Irish Water must continue to address sources of water pollution which impact some of our beaches to ensure that public health is protected.
