The present work is a comprehensive evaluation of drinking water quality from various regions of Greece. The physicochemical parameters investigated were conductivity, total dissolved solids and pH, as well as related to the treatment of drinking water such as chloride, potassium, calcium, magnesium

In the present study the involvement of human activities is assessed in the revalorization of groundwater quality. The groundwater quality was assessed on the basis of physical and chemical analysis (electric conductivity, pH, − − total dissolved solids (TDS), total hardness, NO−, NO2 , SO4 2, Fe, M

The natural zeolite from Evros prefecture contains Ca-rich clinoptilolite (89 wt.%) and in total 92 wt.% microporous minerals (zeolite + mica + clays). Quartz and feldspars constitute the non-microporous minerals (8 wt.%). Acidic water (pH 5.5) from the Kokkinolakkas Stream and basic water (pH 9.5)
