The article describes an experiment involving pumping of groundwater from specific sections of the aquifer with a packer. The aim of the experiment was to identify the vertical differentiation of groundwater chemistry of the Wielkopolska Buried Valley Aquifer near Joanka well-field in order to explain the reasons for the occurrence of "brown water”. The research shows significant vertical and...
This paper describes the quality of ground water in Mount Sinai as an example of ground water quality in the Arabian-Nubian shield. The chemical analysis for the major dissolved solids of about thirty water samples from dug wells and springs were treated by a methodology combining both the graphical and statistical techniques. The impact of the country rocks, atmosphere and human activities on ground...
