An End to the Green Water? Sant Elm Tests Seawater Circulation

Answer

What else does Mallorca need to do if green water problems keep coming back?

If green water keeps returning, circulation alone is unlikely to be enough. Mallorca would also need better monitoring, cleaner sewage systems, proper treatment of boat waste, and measures to reduce runoff from land. Sant Elm’s test may help, but long-term improvement depends on tackling the sources of nutrients as well.
