Groundwater Corrosivity and Scale Formation Tendency in the North-East Area of Sebha City (South of Libya)

Abstract

The aim of this study is to evaluate the ground well water corrosivity and/or tendency toward scale formation using physiochemical analysis data for water samples from selected groundwater wells in north-east Sabha area ( South of Libya ). The result of physiochemical properties , especially pH , conductivity , CO2 , hardness and alkalinity revealed that the water could be corrosive.

The study of the groundwater by application of Langelier, Ryznar, Aggressiveness and Larson ( ratio between halides and sulphates to the alkalinity ) indexes revealed also that the water is corrosive and has low tendency for scale formation .
