Analysis Of Ground Water Quality Of Pre-Monsoon Season Around Ksk Mahanadi Power Plant, Janjgir-Champa (C.G.) India

Abstract

This study Aims to investigate the contamination level of waste water in Janjgir-Champa District, (C.G) by considering some parameters  like pH, Temperature, EC, TH, TDS,  BOD, COD, F^-, Cl^-, NO₃^-_, SO₄^2-, Turbidity, DO, HCO₃^-, CO₃^2-, Ca²⁺, Mg^2+, PO₄^3-, Na⁺, K⁺, alkalinity, TDS, TS, TSS and Heavy metals (Pb, Cr, Fe ,Hg) concentration have been analyzed. Standard methods followed for the investigation of Physico-Chemical parameters and Heavy metals were analyzed through ICPMS method. The objective of the study investigates the pre-monsoon season variation in Physico-Chemical characteristics of water samples of three different sampling stations of Janjgir-Champa, (C.G) namely Nariyara Hand Pump (NR-HP), Banahil (BH-HP) and Tarod Hand Pump (TR-HP) respectively. The PH was found to be of range from 8.4 to 8.1; whereas the Electric Conductivity value ranged from 240 μscm^-1 to 200μs cm^-1. In Addition, the maximum value of temperature was 36.3^oC and minimum 31.5^oC.

Furthermore, the Turbidity value ranged from 90.21 NTU to 10.52 NTU, the BOD values extend from 24.40mg/L to 20.50 mg/L. The COD value covered from 65.25 mg/L to 2.1 mg/L, and the TDS and TSS values ranged from 502.81 mg/L to 555.80 mg/L, TS value varied from 232 mg/L to 658 mg/L and the values of TSS covers the values between 85 mg/L to 72mg/L. Total alkalinity values ranged from 152.81 mg/L to 155.21mg/L, whereas the value varied from 433.56mg/L to 515.51mg/L, fluoride and chloride value ranged from 149.56 mg/L to 173.86 mg/L and 0.849 mg/L to 1.071 mg/L respectively. The values ranged of Phosphate, Sulphate and Nitrate were 0.038mg/L minimum value and 0.083 mg/L maximum value and minimum 110.6mg/L, maximum value 122.6mg/L, and the ranged of sulphate from 201.2 mg/L to 232.6 mg/L respectively. Sodium and Potassium value ranged from 23.8 mg/L to 2.1mg/L and 11.9 mg/L to 12.5mg/L respectively. Bicarbonate and carbonate value ranged from 62.1 mg/L to 70.2mg/L, 21.6 mg/L to 25.7mg/L respectively. In contrast Heavy metal (Pb, Cr, Hg, and Fe) were analyzed and compared with standard drinking water values. The result indicated that the concentration of iron value ranged between 0.8230 mg/L to 0.0159mg/L which exceeded the standards limit, although Pb and Hg value ranged between 0.005 mg/L to 0.010mg/L, 0.0020 mg/L to 0.0004 mg/L respectively and chromium is below the detection limit. The study emphasizes that the health risks associated with was the water for local and aquatic life are critical to t their survival, in the areas the quality of water is very bad at some places and it is unfit for drinking purpose.
