Exploring the aquifers shaping Italy's sub-urban landscape

Abstract

This review paper examines the hydrogeological characteristics and challenges of urban groundwater management in ten major Italian cities: Turin, Milano, Padova, Bologna, Roma, Pescara, Napoli, Bari, Catania, and Cagliari. Urbanization has placed significant pressure on groundwater systems, highlighting the need for sustainable management. The study categorizes the cities based on their hydrogeological settings and groundwater uses, identifying key issues such as salinization, industrial contamination, and land subsidence. The findings emphasize the importance of urban local aquifers (ULAs) for drinking water, industry, and ecological support, advocating for integrated urban water management and governance to enhance resilience against future water shortages and climate change impacts.
