26. CONCLUSION
• The geology of study area consisted of Permian
limestone and dolomitic limestone and Triassic
granite intrusion. The travertine layers were
found only in the upper parts of the hot spring.
• The groundwater quality was temporary hardness
water and suitable for drinking water, as were
below maximum allowable groundwater quality
standard for drinking purpose.
