HARD WATER REGIMES DURING PRE-MONSOONAL PERIOD IN RAJNAGAR BLOCK, ODISHA, INDIA: A GEOSPATIAL ANALYSIS BY GEOGRAPHIC INFORMATION SYSTEM

Prabhu Prasad Das, H. K. Sahoo

Abstract: From the hydrochemical analysis of 53 representative groundwater samples along coastal Kendrapara district, Odisha, the current research establishes widespread occurrences of moderately hard to hard groundwater within the subsurface water bearing horizons. There exists a distinct belt of moderately hard ground water in the Rajnagar block of the district whereas soft water occurrence is practically absent in the study area. The analysis also points to no specific interrelationship between the hardness of groundwater to that of the physical parameters including pH and electrical conductance.
