Characteristics and possible reuse of Favignana Harbor’s sediments

Italy is a country with a high coastal development where multiple activities are located in sites near the coast, which makes the handling of marine sediments a topic of particular interest and socio-economic importance. At present, the excavation of the seabed and the subsequent discharge of resulting materials into the sea represents a risk due to the possible spread of contaminants in the ecosystem. National and international legislation has recognized the immersion of contaminated material into the sea as an event of perturbation to the environment while promoting alternative management options and introducing the concept of sediment as a “resource” and not as a “waste”. There is a wide range of treatment technologies available and they significantly influence the reuse of dredged material. In the present work, a site-specific conceptual model of the small harbour of Favignana is presented and, on the basis of some preliminary analytical tests on superficial samples, the assumptions of management options are predicted. One of them is particularly interesting as it could be applied to other cases where, for reasons of safety of navigation, small volumes of slightly contaminated sand (less than 25,000 m3) must be dredged and, after removing chlorides, they may be used on land to create sporting centres and increase tourist capacity
