Groundwater samples collected at 28 locations were analyzed at sites where VES
were conducted in the study area. A qualitative and quantitative correlation of
hydrogeochemical parameters with a Dar-Zarrouk parameter, longitudinal unit con-
ductance ( S ) parameters is derived and discussed in detail. Contour maps and graphs
are prepared from groundwater quality data and Dar-Zarrouk parameter, longitudi-
nal unit conductance ( S ) is compared to drive the relationship in between them.
