Bathing water samplers set for a busy season of water quality checks

WHILE FAMILIES families across Wales start making plans for the summer, samplers from Natural Resources Wales (NRW) are embarking on their annual programme of bathing water quality tests.

This year, there are 110 designated bathing waters which will be sampled multiple times between 15th May-30th September, in line with the UK Bathing Water Regulations. 109 of these are coastal waters, and one inland lake (Llyn Padarn).

Last month the Welsh Government announced that Nefyn Beach in Gwynedd had been added to the list of designations, following a successful application.

Bathing water samples are sent to NRW’s laboratory in Swansea, where they are tested for levels of Escherichia coli (E. coli) and intestinal enterococci (IE).

Results from a four-year rolling period then determine the classification for the next bathing water season; excellent, good, satisfactory or poor.

Last year, 98% of Wales’s designated bathing waters met stringent environmental standards, with 80 out of 109 meeting the ‘excellent’ criteria.

Clare Pillman, Chief Executive of NRW said: “More and more people are enjoying the benefits of open water swimming, and where better to take a dip than at one of the many fantastic bathing waters Wales has to offer.

“Our blue waters offer a wealth of recreation opportunities, providing a vital boost to Wales’ tourism sector and the health and well-being of our communities.

“Our teams continue to work hard to tackle the many sources of pollution which threaten our water quality, including from agriculture and storm overflows. Much progress is being made, and we are pressing for record levels of water company investment for the environment in the coming years to safeguard the future health of our waters.”

Prior to the start of the traditional bathing water season, NRW officers undertake a number of pre-season checks and samples. This includes checking to ensure permit conditions for nearby discharges are being complied with.

Issues or deteriorations flagged in last year’s results are investigated by local teams to identify any sources of pollution which may be contributing to high bacteria levels found in samples.

Information about where to find designated bathing waters, and the standard of bathing water is available on NRW’s website.
