STATISTICAL EVALUATION OF PHYSICOCHEMICAL WATER QUALITY PARAMETERS FOR ENVIRONMENTAL MONITORING
Keywords:
Water quality assessment, physicochemical parameters, environmental monitoring, waterpotability, correlation analysis, drinking water qualityAbstract
Water quality assessment is essential for ensuring safe water resources and maintainingenvironmental sustainability. Physicochemical parameters are widely used to evaluate the chemicalcharacteristics of water and to detect possible contamination. The present study examines thestatistical relationships among major physicochemical water quality parameters and their associationwith water potability. The analysis was conducted using a secondary dataset consisting of 10,000water samples that included measurements of pH, hardness, dissolved solids, chloramines, sulfate,conductivity, organic carbon, trihalomethanes, and turbidity along with a potability indicator.Descriptive statistics were used to summarize the distribution of these parameters, while correlationanalysis was performed to explore relationships among them. In addition, a comparative analysis wasconducted to identify differences in parameter values between potable and non-potable watersamples. The results indicated noticeable variability across several parameters, particularly dissolvedsolids and sulfate concentrations. Correlation analysis revealed moderate associations amongmineral related parameters, suggesting that multiple environmental factors influence water chemistry.The comparativeanalysis further showed that certain parameters, including trihalomethanes, sulfate,and organic carbon, differed significantly between potable and non-potable samples. Overall, thefindings demonstrate that statistical evaluation of physicochemical indicators can provide valuableinsights into water quality conditions. Such analyses can support environmental monitoring effortsand contribute to more effective water resource management and public health protection.
