Assessment of physicochemical parameters and metal contents of Mansagar lake of Jaipur

Calculation of Quality Indices and Correlation Factors at Some Effluents Entry Points of the Mansagar Lake, Jaipur

“…Table 1 depicts evaluated physicochemical parameters, organic effluents and other pollution contents for these chosen locations. The table is reproduced from earlier reported work [4] with some parameters close to their two decimal values only. Large variations were observed within the physico-chemical, biological and bacteriological parameters, which also indicate that the Jalmahal (Mansagar) lake prevailing a non-uniform nature of the water quality.…”

“…It can be defined by its depth (1.5-4.5 in meters), surface area (139 hectares) and the catchment area, which is 23.5 sq. km [4][5]. The state Government and local municipal agencies have been working hard to manage its heritage value and to maintain the quality of its water since last 2 decades.…”

“…The location (station: E 3 ) was also suitable in view to check the soil erosion effects and its impact on the lake environment. As discussed in [4][5][6][7], standard processes and methodologies were applied to evaluate the physico-chemical parameters and metal constituents for samples collected from stations; E 1 , E 2 , and E 3 . Table 1 depicts evaluated physicochemical parameters, organic effluents and other pollution contents for these chosen locations.…”

Pearson’s Correlation and Trend Analysis for Physico-Chemical Parameters of Mansagar Lake, Jaipur<strong> </strong>

“…The Lake is located in the middle surrounding three hills and was constructed by building a dam over a river; the Dravawati, to address the drought in the surrounding lands [12]. During post-independence era, especially in the year 1962, the city administration diverted the sewage disposal of two large drainstowards the lake and from that stage the situation started getting worst for the fresh water source of the Pink city [12][13][14]. The dimension of the lake can be classified as the water surface area about 139 hectares and the catchment area of 23.5 sq.…”

“…To analysis the water quality assessment of the studied lake, rigorous efforts have been placed to evaluate important physico-chemical parameters for its water. Standard procedures for sample collection and evaluation of physico-chemical parameters have been applied as discussed in our previous work [14]. As part of exercises, many roundsphysical and chemical tests were performed to calculate factors like pH, turbidity, DO, COD, BOD and many others.…”
