Multivariate Statistical Analysis for Water Quality Variation in Baraila Lake, Bihar, India

The Baraila Lake plays an important role in conservation of the plant and animal species in Vaishali, Bihar, India. Since, water quality of this Lake is utilized for different human purposes, complete periodic chemical and physical quality assessment of its water seems necessary. Water quality assessment was calculated using the following parameters:- Water Temperature, PH, Turbidity, Dissolved Oxygen, Chloride, Alkalinity, Phosphate, Nitrate, Ammonia, Fluoride, Sulphate, Chemical Oxygen Demand , Biological Oxygen Demand, TDS, TC and FC. There is no such spatial variation in concentration of water quality observed during the study period. The correlation matrix shows that the micronutrient and macronutrient concentration is negatively correlated with alkaline nature of Baraila Lake. The lake manager needs to study the monitoring of water quality parameters of Baraila Lake on seasonal basis.
