Correlation between resistivity in rock mass and groundwater quality is shown from the results of investigation such as borings and geophysical exploration. Electrical resistivity survey had been done to understand impact on behavior of groundwater by construction of underground research laboratory. This paper shows distribution of resistivity around underground research laboratory obtained from electrical resistivity survey.
