framework for contaminated sites, but areas outside the goods and tourism services. The possibility to realized
contaminated sites of national interest still require a specific beach nourishment will be strongly influenced by eco-
attention,as specified by § 8, art.48 of the Italian Legislative toxicology behavior and the presence of the Posidonia
Decree of 24th January 2012 [7]. In Favignana, where the oceanica meadow in shallow water (close to the shore
