Dún Laoghaire Baths: Council Declares Safe for Swimming Despite EPA Warning

A disagreement has emerged regarding the Dún Laoghaire Baths, a popular local spot. Dún Laoghaire-Rathdown County Council states the waters are "currently rated as excellent and the location is safe for swimming." In contrast, the Environmental Protection Agency (EPA) maintains its assessment, classifying the bathing waters as "poor" quality and warning that "the water is not safe for swimming." This conflict creates confusion for potential swimmers.

This situation highlights challenges in assessing public health and safety for natural amenities. The Baths became an official bathing area last year after significant investment, including a new jetty and improved access. This provided a much-needed designated spot for sea swimming. The current conflicting reports are a setback, especially with summer approaching.

The EPA's Stance: "Poor" Quality and Restrictions

The EPA has classified the Dún Laoghaire Baths as "poor" quality for the 2026 bathing season. This classification, they explain, means bathing restrictions will apply. Their reasoning is that the site is vulnerable to pollution. They explicitly state that a "poor" classification indicates the water is not safe for swimming. For the EPA, the scientific findings are conclusive, and regulations are in place for a reason.

This system is not new; it follows EU and national regulations, applied consistently across EU member states and Ireland's 153 bathing sites. Testing occurs during the official bathing season (June 1st to September 15th), with results from one year determining the classification for the next. The EPA points to two pollution incidents in July 2025 as the basis for their current "poor" ranking. These incidents, according to the EPA, caused the waters to fail the quality test, leading to the current classification.

The EPA insists that any advisory notice should clearly state that the water may pose a health risk and advise against swimming. They are being direct about this.

The Council's Counter-Argument: "Excellent" Conditions Now

Dún Laoghaire-Rathdown County Council views the situation differently. They acknowledge the EPA's "poor" classification but argue it relies "solely on 2025 results." Their main point of contention centers on the timing of the testing and what they consider the present conditions.

The council states that when water quality is assessed over the full 2023-2025 period, it actually meets "good" standards, with 91% of samples rated "excellent." They attribute the "poor" ranking to "two isolated incidents in July 2025," which they say "do not reflect the overall good water quality at the site."

Notably, the council has been taking samples outside the official bathing season, reporting that all but one sample taken so far in 2026 have been "excellent." They have published these results on their website and social media, and updates are also available on the beaches.ie website.

While the council plans to erect an "advisory notice" at the Baths referencing the EPA's assessment, they emphasize this is not a prohibition notice. Their advice to bathers, as of Friday, is "to be reassured that current conditions indicate the water is safe for swimming." This creates a confusing situation: an advisory notice suggesting the EPA deems it unsafe, while the council declares it safe.

The Root of the Disagreement: Testing Protocols

The core of this dispute appears to stem from how bathing regulations and testing protocols are interpreted and applied. The EPA notes that samples analyzed by Dún Laoghaire-Rathdown in 2023 and 2024 were "not collected as per the Bathing Water Regulations," and no sample calendar was submitted for their oversight. This means, in the EPA's view, these samples are "inadmissible to the EU" for official classification purposes.

Essentially, the EPA is saying that the council's data, while perhaps valid in its own right, does not meet the strict regulatory framework required for an official "safe" designation under EU law. The rules must be followed precisely for official classifications.

What Does This Mean for Swimmers?

So, what should swimmers do? On one side, the national environmental watchdog says the water is "poor" and "not safe." On the other, the local council says it's "excellent" and "safe."

This feels like a bureaucratic conflict, but it has real implications for public enjoyment and health. The council is trying to manage a situation where official past data (the 2025 incidents) leads to a current warning, even if more recent, unofficial testing shows improvement. The EPA, correctly, adheres to the letter of the law and the established regulatory framework designed to protect public health.

For now, an advisory notice will be in place. Individuals must weigh the information and decide. The Dún Laoghaire Baths are a valuable amenity, and hopefully, this dispute can be resolved quickly, with clear, unambiguous guidance for everyone. Transparency and consistent information are crucial for maintaining public trust, especially concerning water safety.
