La contaminazione delle risorse idriche sotterranee a causa di una fuoriuscita di percolato da discarica ha creato gravi problemi socio-economici ed ambientale in diversi paesi. Infatti, molte delle discariche esistenti e quelle abbandonate, ancorché non adeguatamente controllate o gestite, possono costituire una grave problematica sanitaria ed ambientale. La scelta del sito per lo smaltimento dei rifiuti deve necessariamente scaturire da uno studio rigoroso basato sulla valutazione integrata della pericolosità ambientale dell’impianto stesso, delle caratteristiche idrogeologiche e del grado di vulnerabilità intrinseca all’inquinamento delle falde acquifere. Nel presente lavoro viene proposto un Sistema Integrato per la Valutazione del Rischio Ambientale da Discariche di rifiuti solidi urbani (SIVRAD). L’analisi integrata della vulnerabilità intrinseca del sistema acquifero e la stima della pericolosità potenziale intrinseca consentono di valutare l’idoneità dei siti ad ospitare una discarica e di definire la priorità di bonifica ed il sistema di monitoraggio per gli impianti esistenti. Inoltre, per le nuove discariche, la metodologia descritta permette di suggerire una migliore strategia di costruzione per la tutela dell’ambiente circostante. Infine, questo approccio metodologico è stato applicato in discariche situate in diversi contesti geologici ed idrogeologici.

Abstract

In recent years, the contamination of the underground resources from landfill leachates is recognised as a serious socio-economic and environmental problem in many countries. In fact, the existing not adequately controlled and abandoned sites, constitute a serious sanitary and environmental problems. The choice of the waste disposal site must necessarily arise from a rigorous study based on the joint assessment of the environmental hazard of the same plant and the hydrogeological characteristics and the degree of intrinsic vulnerability to pollution of the aquifers. In the present paper an integrated system for the assessment of the environmental risk from solid waste landfills is proposed. The integrated analysis of the intrinsic vulnerability of the aquifer system and the estimate of the intrinsic potential hazard caused by the landfill expressed in terms of danger index allow to evaluate the suitability of the sites to host a landfill and to define the reclamation priority and monitoring system for the existing landfills. As concerns new landfills, the proposed methodology could also support a better construction strategy and the protection of the surrounding environment. Finally, this methodological approach was applied in landfills located in different geological and hydrogeological contexts.
