ducting water quality analysis at few sites. The correlation can be improved to fur-
ther levels if the geophysical data is collected exactly at the same spot from where
the water samples are collected from bore wells for chemical quality analysis. The
qualitative and quantitative results shown in the correlation patterns and correlation
graphs clearly illustrate the geophysical expression of water quality.
