Last summer the first measure in Björnöfjärden, in Stockholm archipelago, was taken within the project Living coast; aluminium treatment to bind phosphorus in the bottom sediments. A year ahead the treatment is completed. As a result of the measure we already see a better water quality.
This is how it looked like in August, when the underwater photographer Joakim Odelberg took some photos the bay.

Aluminium treatment is an effective method to bind phosphorus and the bay gets a chance to recover. For more information about the measure, click here.
