pH
The concentration of hydrogen ion present in the water is more
important, and it helps to identify the nature of groundwater whether
the water is acidic or alkaline (Aravindan et al., 2010). However, the
pH of groundwater in the study area ranges from 7.3 to 8.2, with an
average of 7.8. It shows that the pH value for all the sample locations
is most suitable for drinking purposes recommended by WHO (2011) and BIS
(2012) standards. In the spatial analysis, an acceptable level of pH
covers 666.95 Sq.km (Fig.3a).
