Hydrogeological surveys

During both Phases I and II, 71 piezometers were installed to monitor groundwater. A total of 221 water samples were collected and 9463 analyses were carried out. Seven field surveys sampled shallow and deep groundwater, analyzing various physicochemical parameters (e. g., pH, Eh, dissolved 02, temperature, conductivity), and the presence of potentially harmful elements and compounds (e.g., heavy metals, hydrocarbons, PAH). The hydrogeological survey carried out by the Bagnoli SpA, concluded that...

When sufficient testing and surveying of the well site has not been undertaken, it is possible that the concentrate may be injected into or above an unknown potable aquifer. Thorough hydrogeological knowledge of area is therefore required to avoid such mistakes.
