Structural Characterization of Waste Material and Leachability Tests

Chemical-Structural Characterization of Waste Material and Leachability Tests 

Chemical—structural analysis and leachability tests on scum, slag, and Fe-minerals were carried out to characterize and measure the chemical stability of the metals in waste materials. The investigation was designated to (1) evaluate the 

Microscope analyses and leachability tests showed that the microstructural configuration of materials at the site are stable not only relative to the tests and procedural time frame but also because of the recognition of the absence of isolated microstructures made of heavy elements. Heavy elements are most likely trapped in the lattice of the detected relatively insoluble microstructure phases, and leaching of these elements is highly unlikely. In conclusion, the industrial waste present in the brownfield site of Bagnoli is unlikely to contribute metallic pollution to local groundwater, on a reasonable human time scale. Numerous investigations carried out on industrial steelwork waste in the European Community have reached the same conclusions. 

The CIPE plan called for a remediation of asbestos-containing materials in the Etemit and in the ILVA steelwork factories. Ninety percent of the buildings, squares, and sites were cleared of asbestos by March 4,2000. During the remediation activities, and in coordination with the local Health Unities (ASL)), a series of control samples were collected. 915 samples were analyzed to evaluate the presence of aerially dispersed asbestos fibers in nearby locations. No values exceeding WHO limits were detected. 1044 samples and analyses from the Etemit site and 56 from the ILVA site were also collected to monitor fiber dispersion inside the area of the operations. 

The draft reclamation plan adopted the following guidelines
