INFLUENCE OF LOCAL AND LARGE SCALE HYDROMETEOROLOGICAL FACTORS ON INTERANNUAL GROWNDWATER NITRATE REGIME IN RURAL SETTLEMENT

The study analyzes the spatial distribution of groundwater nitrate concentration in Siculeni, a rural settlement in Eastern Transylvania. The aim of the paper is to determine the factors influencing the inter-annual regime of groundwater nitrate concentration. In the analyze groundwater nitrate concentration and water table data are used from 23 sampling points and also precipitation data from Miercurea Ciuc meteorological station are processed. Based on combined cluster analyzes with geographical information system tools the role of point wise communal pollution sources on nitrate concentration are demonstrated, on the other hand the significant empirical relationship between precipitation and groundwater nitrate concentration is argued via introducing an intermediate variable, namely the groundwater table fluctuation. This emphasizes the fact that groundwater nitrate concentration is partly determined by communal local factors and also partly by large scale processes

Groundwater investigation in Paphos region

Cyprus is a semi-arid island. Its water resources rely on winter rainfall which supply the impounding reservoirs constructed on the dry river courses and replenish the groundwater resources within the river gravels or the plain aquifers. water requirements for domestic use and irrigation have been increasing considerably for the last ten years. The potential of the conventional water resources have been developed according to techno-economic factors. Also, the unconventional sources (treated domestic effluents and desalinating sea water) are receiving particular attention to support water requirements throughout the island. The current study deals partly with the calcarenite aquifer of the Paphos Coastal Plain. It has been investigated whether this resource is offered for an integrated exploitation program. In addition the domestic effluent of the Paphos urban zone is considered as a promising resource for providing reliable and continuous quantities for irrigation use after treatment. [Continues.
