SPATIOTEMPORALDYNAMICITY OF ENVIRONMENTAL VARIABLES AND WATER QUALITY INDEX IN AQUIFERS AND GROUNDWATER OF BLUE CITY USING MULTIVARIATE STATISTICAL TECHNIQUE.

Thecurrent research investigates the quality of ten different surface water sites in and around Jodhpur using water quality ratings. This paper gives insight into water pollution's qualitative and quantitative extent. The water quality index (WQI)is usedfor assessing and comparing water quality. In each study region, a five-point grading scale was adopted to classify water quality as a single understandable value. Twelveparameters were employed for determining the WQI of different sites: turbidity, TSS, TDS, conductivity, alkalinity, hardness, calcium, magnesium, chloride, fluoride, and nitrate. Multivariate analysis of the samplesrevealed that most of the individual parameters are not in harmony with the standard values prescribed by the regulating authorities. According to the study, seasonal fluctuations play a significant effect in the hydrochemistry of surface water, indicating a change in WQI. Thesamples showed less pollution in the pre-monsoonseason as compared to post-monsoon. Overall, this paper lays forth a strategy for proper utilization and protection, as well as assesses the quality of surface water to determine its suitability for various uses and its impact on groundwater quality.
