Confined dumpsite to be used as container terminal in the Port of Naples
Design of the new Terminal, clean-up and management of polluted materials, quality characterization of the landfill material, construction of a groundwater cut-off wall and design of drainage pipe system to control piezometric levels.
Project: Design and environmental impact assessment for the construction of a confined dumpsite to be used as container terminal in the Port of Naples.
Location: Naples, Italy
Client: Port Authority of Naples
Cost of total Works: 4,000,000.00 €
Services: Preliminary Design and Environmental Impact Assessment
Period: 05/2003 – 01/2008
The design of a new container terminal at the Levante Dock (Port of Naples) is based on the closure of the dock with landfill of soils and sediments from the industrial area of Bagnoli. Due to the low permeability designed for the construction walls, the new terminal was planned to be also used as a confined disposal facility (CDF).
The design of the Terminal was approved by the Italian Ministry of Infrastructure and Ministry of the Environment. Regarding environmental protection, the design foresees a very low permeability of walls and bottom of the CDF, clean-up and management of polluted materials, quality characterization of the landfill material, construction of a groundwater cut-off wall and design of drainage pipe system to control piezometric levels.
At Levante dock, the project comprises the complete closure of the existing dock with a double sheet-pile wall, clean-up of bottom sediments (characterization and confinement of hot spot soils to a disposal site), protection of the area by a cut-off wall in order to prevent polluted groundwater to enter in the CDF.
At Bagnoli, the project design comprises clean-up of existing hot spots (excavation and transfer of polluted materials to a disposal site), transfer of the remaining landfill material qualitatively suitable for Levante CDF by barge.
A hydrodynamic and dispersive model was applied at Bagnoli to select the best technology for the excavation of the landfill site.
For the purpose of Environmental Impact Assessment noise and air modeling was applied to assess impacts induced by the construction site.
Further to Environmental Impact Assessment, environmental risk analyses were performed to properly manage polluted material and avoid detrimental effects to the environment and human health, due to the vicinity of the port to the city of Naples.
