Physico-Chemical Analysis of Surface and Groundwater around Talcher Coal Field, District Angul, Odisha, India ()
ABSTRACT
The present study deals with the water quality of
Talcher Area. Sample was collected from Ghats of river Brahmani, tube well and
tap water of different colonies in Monsoon and in Post Monsoon. The collected
sample was analysed in P.G Department of Environmental Sciences, Sambalpur
University. The parameters studied were DO, pH, Conductivity, Temperature,
Sodium, Potassium, Dissolve Oxygen, Total Solid, Chloride, Alkalinity,
Hardness, Sulphate, Chemical Oxygen Demand, Nitrate, Phosphate and Fluoride.
Water quality index was calculated by using NSF water quality index. Analyzed
data were compared with the standard IS: 2296 (Surface Water Quality Standard)
and IS: 10500 (Drinking water Quality Standard). The maximum pH of 7.91 ± 0.17 was
found at Jagannath Ghat. Maximum average conductivity was found as 559.28 ± 8.92
μS/cm in tube well water of Jagannath colony and minimum was 90.66 ± 1.15 μS/cm
in Tarini Ghat. Temperature was maximum 28.5°C ± 0.36°C in tube
well water of C.W.S. Colony. The maximum Sodium, Potassium, Chloride,
Alkalinity and Nitrate content was recorded as 12.37 ± 1.23, 95.9 ± 7.75,
541.66 ± 2.84 and 24.27 ± 0.61 mg/L respectively in tube well water of Balanda
colony. The high dissolved oxygen content was recorded as 7.92 ± 0.34 mg/L in
tap water of C.W.S. colony. Maximum hardness value was recorded as 326.69 ± 5.30
mg/L in tube well water of C.W.S. colony. The high value of COD and Sulphate
was recorded as 188 ± 8 and 132 ± 5.43 mg/L in tube well water of Jagannath
colony. Maximum Phosphate and Fluoride content was recorded as 423.27 ± 2.59
and 664.23 ± 5.03 μg/L respectively in Paschimeswar Ghat. Statistical
calculation was subjected to two-way ANOVA and Correlation coefficient.
