Abstract
Problem statement: The aim of this study is to make an attempt to assess, through the application of the Holman Method, the effects that a careless management of human induced activities could have on aquifers and in particular on tapping wells used for human supply. Approach: The study had been applied to two different territories, as far as both the geomorphological and human induced aspects are concerned: the city of Aosta, the capital city of the Autonomous Aosta Valley region and three municipalities located in the centre of the Veneto region. Results: Thanks to the first results that had been obtained from the application of this method and other ones, it is hoped that a strategic territorial management approach will be adopted in the future so that the Groundwater Resources (GWR) can coexist with the economic and urban developments. Conclusion: All the analysis had been implemented utilizing a Geographical Information System (GIS).

Summary
The Holman method[10] is applied to calculate the potential impact of Hazard Centers (HC) on Groundwater Resources (GWR) and in particular on tapping wells used for human consumption. Application of the Holman method involves an accurate census of the types of HC that are present in the examined area in order to highlight the activities that are responsible to the greatest extent for the pollution of groundwater and to draw up a classification of the potential hazard. The Hazard Factor index, which is calculated as the product of the hazard factor weights: HFI = A × B × C × D. The control factor index, which is calculated as the product of the control factors: CFI = E × F × G. Pathogenic bacteria and viruses Substances able to change organoleptic characteristics
