The state of Rajasthan of India is predominantly classified as a dry state and therefore its freshwater and agricultural resources are the prime concern for the people and the state agencies. This article presents the analytical study of physicochemical parameters of Mansagar lake Jaipur, India. Our prime objective was to find the quantity and effects of effluents mixing with the water of Jalmahal Lake (officially known as Mansagar lake). Standard approaches were applied to calculate the water quality index (WQI) for the assessment of its surface water for two consecutive years. The values of physicochemical parameters have been calculated before and after the rainy season and the study has been presented in a detailed form. The variation of parameters like COD with heavy metals like lead and zinc have been analyzed and it is found that due to the increase in metal content the COD increased as high as 500 mg/l in rainy while it is as low as 200 before the rainy season. The values of various physiochemical parameters like BOD, COD, conductivity, and turbidity were also observed throughout the year at the various front of the lake and it has been observed that pollutants presence increases in peak summer and late winters. It’s noticeable that turbidity and conductivity were normally high in June–July thereby increased pollution concentration in the remaining water levels.

印度的拉贾斯坦邦主要被归类为干旱州，因此印度的淡水和农业资源是人民和国家机构的主要关注点。本文介绍了印度斋浦尔曼萨加湖理化参数的分析研究。我们的主要目标是发现污水与贾马哈尔湖（正式称为曼萨加湖）的水混合的数量和影响。应用标准方法来计算水质指数（WQI），以连续两年对其地表水进行评估。已在雨季前后计算了理化参数值，并以详细的形式介绍了该研究。分析了COD等参数与铅和锌等重金属的变化，发现由于金属含量的增加，在雨天，COD的增加高达500 mg / l，而在雨天之前的低至200 mg / l。季节。全年在湖泊的各个前沿也观察到了各种理化参数的值，例如BOD，COD，电导率和浊度，并且观察到污染物的存在在夏季高峰和冬季末增加。值得注意的是，6月至7月的浊度和电导率通常很高，从而增加了剩余水位中的污染浓度。全年在湖泊的各个前部也观察到了浊度和浊度，并且观察到污染物的存在在夏季的高峰和冬季的末期增加。值得注意的是，6月至7月的浊度和电导率通常很高，从而增加了剩余水位中的污染浓度。全年在湖泊的各个前部也观察到了浊度和浊度，并且观察到污染物的存在在夏季的高峰和冬季的末期增加。值得注意的是，6月至7月的浊度和电导率通常很高，从而增加了剩余水位中的污染浓度。
