Water quality

The Bizkaia County Council Environment Department, in conjunction with the Basque Government’s Ministry for Health, has been carrying out the health monitoring of the bathing areas of our county. This has ensured that continuous information is available on the quality status of the beaches, along with identifying the points situations where there is a possible risk.

The quality of the bathing water is checked at all beaches from May to October. Every fortnight (weekly in July and August), water rating and the sanitary bathing conditions are established according to the results at each of the sampling points.
