- Abstract
This paper examines the quality of groundwater in a 40 sq km region comprising Osmania University and surrounding
areas in the north eastern part of Hyderabad city in India. 171 groundwater samples from bore wells in the region have
been analyzed for ionic concentrations of K+, Na+, Ca2+, Mg2+, F-, Cl-, SO4
2-, HCO3
- and NO3
2-. Parameters such as pH,
total hardness (TH), total dissolved solids (TDS), sodium absorption ratio (SAR), permeability index (PI), residual
carbonate (RC), electrical conductance (EC) and groundwater quality index (GWQI) have been evaluated, contoured
and analyzed to determine the areas of contaminated groundwater. It is inferred from Wilcox plot and Piper trilinear
diagram, the samples in the study area falls under C3S1 class and characterized by alkaline. It was found the
groundwater in the entire region is too hard for drinking. Groundwater contamination in the study area is attributable to
different sources; in the southern part of the study area, it is due to proximity to the river Musi that acts as a carrier of
domestic and industrial effluents. In and around Nacharam and Mallapur, the effluents discharged from the several
industries are responsible for polluting the groundwater in the region. Regions such as Jamai Osmania, Lallaguda and
Lalapet are very densely populated and it is the domestic sewage in this area that is the primary cause of groundwater
contamination.
