The largest portion of the Earth’s freshwater is bound in ice or occurs as deep groundwater. The freshwater available for human uses is shallow groundwater and water in rivers, lakes, manmade reservoirs, and streams- about 4.6 million km3 or 12% of the freshwater in the hydrosphere (Boyd, 2015). Water is essential for all forms of life and makes up to 50 to 97% by weight in plants and animals and about 70% human body.

The results are presented on seasonal basis i.e. pre-monsoon (February-May), monsoon (June-September) and post-monsoon (October-January) seasons. For detailed investigation, 4 sampling sites were selected and water samples were collected at monthly interval. The findings on various water quality attributes with value range in parentheses are as- pH (6.1-7.9), dissolved oxygen (5 to 7.9 mgL-1),biological oxygen demand (1.1 to 3.8 mgL-1), chloride (5.2 to 47.5 CaCO3 mgL -1), total alkalinity (25.6 to 186 mgL -1) and total hardness (18 to 181 CaCO3 mgL-1). The findings were compared with the standards given by several scientific agencies for potable water . The pH, DO, chloride, total alkalinity and total hardness were within the prescribed limit, however, BOD was beyond the limit. The data were subjected to correlation coefficient among different variables using SPSS version 16.0 software to check the validity and significance of the result.

The samples were collected on a monthly basis and the results were presented on a seasonal basis, i.e., Post-monsoon (October-January), Pre-monsoon (February-May) and Monsoon (June- September) season. It was observed that temperature ranged from 16.70C to 26.70C; total dissolved solids from 24.7 mgL-1 to 148.5 mgL-1; electrical conductance from 23 μS to 277.2 μS and turbidity from 2.3 NTU to 5 NTU. The findings were compared with water quality standards given by USPH, BIS, WHO and ICMR.
