Since the Congress will be held in Europe, the leading theme on ' Groundwater quality sustainability' is linked with implementation of the EU Water Framework Directive. The year 2010 is the time when the formulation of programmes aimed at preventing further deterioration of groundwater quality in EU Member States must be completed.

The Congress is aimed at scientists, researchers, students, engineers, water resources specialists, consultants, officials, government administrators and educators, and those interested in groundwater and the environment. It will enable them tto exchange ideas, knowledge, experience, techniques and the know-how in studies, investigations and practical applications related to groundwater issues. An important task of the Congress will be to communicate more effectively with the general public and non-groundwater specialists.
