Periodic Water Quality Monitiring of Surface Water in Korba District (C.G.) India

Abstract

In this present attempt, the surface water source of Korba district was studied for the know-how of its quality depletion over a period of time. During the analysis period, nine water sampling sites were selected, assigned from KDS-1-to KDS-9. Water samples were collected in pre-cleaned polyethene and glass bottles of 1L capacity from March-2010 to May-2010 (pre-monsoon). The collected water samples were analyzed as per the standard methods. Results were compared with standard values prescribed by BIS (1991) and WHO (2008). Except for fluoride (1.17) and Dissolved Oxygen (4.411mgL-1), remaining all parameters were exceeded the desired limits. It was quite evident from the data that significant strong positive correlation was observed across Fe Vs TDS (r=+0.961), Fe Vs Hardness (r=0.961) Fe Vs phosphate (r=0.961) Fe Vs Al (r=0.961). On the contrary, Do and TDS related negative high degree correlation (r=-0.792). Calculated WQI revealed that entire water sources were highly polluted by the undesirable chemical constituents; hence water sources of the present study area might not be useful for any purposes.
