wAbstract
@This paper refers to the development of a conceptual model for
the management of a coastal aquifer in northern Greece. The research
presents the interpretation and analysis of the quantitative (groundwater
level recordings and design of piezometric maps) regime and the
formation of the upcone within the area of investigation. Additionally
it provides the elaboration of the results of chemical analyses
of groundwater samples (physicochemical parameters, major chemical
constituents and heavy metals and trace elements) of the area
which were taken in three successive irrigation periods (July-August
2003, July-August 2004 and July 2005), in order to identify areas
of aquifer vulnerability. The study identifies the areas where
ion exchange phenomena occur, as well as the parts of the aquifer
where the qualitative degradation of the aquifer system is enhanced.
The paper, finally, assesses the lack of any scientific groundwater
resources management of the area by the local water authorities,
as well as the current practices of the existing pumping conditions
scheme as applied by groundwater users.
