Bathing Water Quality

Open data from Natural Resources Wales

Water quality at designated bathing water sites in Wales is assessed by Natural Resources Wales. From May to September, regular assessments measure current water quality, and at a number of sites daily pollution risk forecasts are issued. Annual ratings classify each site as excellent, good, sufficient or poor based on measurements taken over a four year period.
