78% Of Ireland’s Bathing Sites Have Excellent Water Quality.

  • The quality of Ireland’s bathing water continued to improve in 2021, with 97% (144 of 148) of sites meeting or exceeding the minimum standard.
  • Of these, 115 bathing sites (78%) had excellent water quality (which is the most stringent standard). This increased from 111 in 2020.
  • These improvements are a result of enhanced management of bathing waters over many years, combined with investments in treatment of urban waste water.
  • The number of beaches with poor bathing water quality reduced to two, compared with four in 2020.
  • Swimmers are encouraged to ask their local authorities to officially identify additional local bathing sites. This will ensure they are managed to protect bathers’ health.

The Environmental Protection Agency (EPA) has today published the Bathing Water in Ireland report for 2021, which shows that 78% of bathing sites have excellent water quality, while 97% meet the minimum standard. This is attributed to improved management of bathing waters over many years, combined with investments in treatment of urban waste water.
However, while bathing water quality has continued to improve overall, there are still issues which need to be addressed, to protect and further improve bathing waters. Agriculture, urban waste water and fouling from dogs on beaches still impact the quality of bathing waters. In addition, heavy rainfall can also quickly impact by washing pollution into our bathing waters. Swimmers should always check for the latest water quality information for their local bathing site.
Commenting on the report, Dr Eimear Cotter, Director of the EPA’s Office of Evidence and Assessment, said: “Bathing water quality in Ireland is high and last year saw further improvements compared with 2020. This is good news as we approach the summer when we can enjoy our local beaches and bathing areas, which are an important natural amenity for health and wellbeing.
The EPA recognises that swimming is increasingly becoming a year-round activity and encourages the provision of information that will help winter swimmers to make informed choices to protect their health. The findings and outcome of the multi-stakeholder National Bathing Water Expert Group, due later this year, will provide important information in this regard and help identify potential options to better protect bathers who swim year-round.”

The EPA report specifically highlights improvements at Lilliput, Lough Ennell in Westmeath, after three years of poor quality. During 2020 and 2021, the bathing water quality improved significantly due to actions taken by farmers in the surrounding area. This was driven by evidence and science generated by Westmeath County Council, the Local Authority Waters Programme and the Agricultural Sustainability, Support and Advisory Programme working together. As a result, the restriction on swimming has been removed.
The EPA encourages swimmers to engage with Local Authorities to officially identify additional local bathing sites which will ensure they are managed to protect bathers’ health.
