The groundwater in the study area is mainly alkaline in
nature. The abundance of major ions are in the
following order Na+>Ca2+>Mg2+>K+ = HCO3->Cl-
>SO4
2->NO3->CO3
2-. The concentrations of cations
such as Na2+ and Mg2+ exceed the maximum allowable
limits for drinking water at some locations which are
near to the MSW dumping yards in the study area. Ca+
concentrations in the groundwater, however, are within
