Abstract
This paper presents a concept of an integrated geodatabase for surface water, soil and groundwater pollution with arsenic in the upper part of the Ogosta Valley (Northwestern Bulgaria) using ArcGIS™ (ESRI®) file geodatabase. A geodatabase model diagram is created
to enable data storage and to meet research requirements ensuring clear geodatabase structure. Further research and activities in this area will focus on the extension and upgrade of the geodatabase to a web format with different levels of data access to support the long-term monitoring and analysis of surface water and groundwater contamination with heavy metals in the investigated area.
