Abstract:
The fresh drinking water is required to prevent the waterborne diseases and to improve the water excellence. The water excellency's interpretation made for the quality assessment of two distinct surface water resources in Ranchi district. A significant number of individuals in Ranchi's urban region rely on the Dhurwa and Kanke dams for drinking water and other household necessities. The different distinct physicochemical parameters will help to identify sources of pollutant. The surface water samples have been collected from three distinct locations of Dhurwa and Kanke dams. The analytical assessment for physicochemical parameters have been made by using different instrument and IS: 3025 method. The found result shows that various physicochemical parameters of Dhurwa and Kanke dam water samples exist beyond the BIS permissible limit, and some are beyond prescribed limit of BIS. The statistical analysis has been made to assess the quality of water. In addition, the water quality index (WQI) for the three distinct sampling locations of Dhurwa dam is 64.53, 62.54, and 65.58, while the WQI for Kanke dam is 117.48, 119.97, and 99.76, respectively. The water sample from Dhurwa dam is of higher quality than that from Knake dam. Also, the correlation matrix variation observed for each parameter in which the effective change in each parameter shows in respect of other parameter. The current research was compared to previous studies, and certain parameters improved while others declined. From the results, it was found that water sample from Kanke's dam obtained poor quality compared to Dhurwa's dam. Agricultural runoff, industrial discharges, and inadequate wastewater treatment all have a negative impact on the water quality in the Kanke's dam studied region.

Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
