AN EVALUATION OF THE WATER QUALITY IN ANNA SAGAR, AJMER (RAJASTHAN) DURING THE YEARS 2023- 2024.

The current study was carried out with the purpose of determining the physicochemical properties of a water sample taken from the Anna Sagar Ajmer , which is located in the Ajmer metropolitan area. A wide range of physicochemical properties, such as pH, total hardness, total alkalinity, chlorinity, turbidity, and dissolving oxygen, were investigated using the samples that were connected to the laboratory.The quantity of phytoplankton,which is the primary source of nutrition for aquatic organisms,decreased as a result of increased pollution.In addition,the salinity of the water has an effect on aquatic organisms that migrate. Amarong the factors that have contributed to the decline are environmental modifications, litter, water pollution, deforestation, trash removal, hazardous chemicals, human disturbance, pesticide spread,agrochemical contamination,global warming,and other factors.The findings indicate that a number of the water samples include chemical constituents that are elevated to levels that exceed the acceptable limits set by the Bureau of Indian Standards (B.I.S.).These chemical constituents have a wide range of adverse consequences. In the purpose of this investigation, the term "regional water contamination" will be used to refer to any type of water pollution that may be identified at the regional level. Taking into consideration these findings, it is recommended that any water source located within the research region be analysed prior to its utilization for its portability as well as various applications in the home or industrial setting.
