Piper diagram
Piper plot of groundwater in the study area shown in Fig. 5. It reveals
that, partial number of sample locations is mixed Ca-Mg-Cl type, 26.66%
of the sample locations are Ca-Cl type, and 23.34% of the sample
locations are Ca-HCO3 type of groundwater. The results indicate alkalis
earth metals, weathering, rock water interaction, inadequate rainfall,
evaporation, and anthropogenic activities are major factors that
influence the nature of groundwater in the study area. The major ions
such as Ca2+, Mg2+,
Cl- and HCO3- are
highly dominate the quality of groundwater.
