Evaluation of underground water's quality in the Central Romanian Plain (Campia Teleormanului) by GIS Techniques

ABSTRACT. – Regarding the ecological criteria for environmental conditions preservation and improvement, groundwaters qualitative status represents WFD’s 2000/60/EC one of the main requirements and a permanent preocupation for the hydrological resources management. The scope of the paper is to analyse, from hydrochemical point of vue, the phreatic groundwater bodies that are delimited in a large area constituting the central part of the Romanian Plain, comprised between Olt and Arges rivers. The methodology consist in processing the data base through GIS applications. For a selected period of time, comprised between 1970-2005, a trend evolution for some chemical parameters was also studied. The results of this study are represented on GIS format maps and charts, that reveales a temporal and spatial distribution of the selected variables.
