The analytical results of physical and chemical
parameters of groundwater were compared with the
standard guideline values as recommended by the world
health organization for drinking and public health
purposes. The Table 3 shows the most desirable limits
and maximum allowable limits of various parameters.
The concentrations of ions, such as Ca2+, Mg2+, SO4
2-
with in the maximum allowable limits for drinking.
However, Na+ and Cl- ions exceed the maximum
allowable limits for drinking purposes. Pipers Diagram
was prepared using software to analysis various
concentaration of chemical parameter shown in Fig 3
The concentration of cation Na+ is good for drinking
purposes at many places. The total hardness values are
found to exceed the maximum permissible limits at
many places. Sodium ion concentration in the ground
water varies from 7.82 to 448 mg/l with an average
value of 124.41 mg/l . The calcium ion concentration
varies from 20 mg/l to 320 mg/l with an average value
of 109 mg/l. All the samples are with the permissible
limits. Potassium concentration is comparatively low.
Bicarbonate, the dominant anion in the study area,
varies between 30.5 mg/l and 750 mg/l (average 431
mg/l). chlorides occur in all natural waters in widely
