Quality of bathing waters in Menorca
A team of biologists and environmentalists from the Observatori Socioambiental de Menorca (OBSAM) is working on a study to evaluate the quality of bathing waters in the coves of Menorca, using brown seaweed of the genus Cystoseria as bioindicators. The project takes samples from the same 103 coves that were analysed in 2005 using the same methods.
Over the last few summers, reports about the proliferation of microalgae some of the island's coves have become more frequent. The water in these coves turns green deteriorating their image and on certain occasions have to be closed to bathing. The study will allow us to assess if the increase in wastewater and tourism pressure, in addition to other disturbances, has affected water quality. The results will encourage the adoption of effective measures to prevent “green water” episodes and improve water quality.
