CORRELATION AND REGRESSION ANALYSIS OF PHYSICOCHEMICAL PARAMETERS OF CHAMBAL RIVER WATER IN DCM INDUSTRIAL AREA OF KOTA (RAJASTHAN)

Rivers are the soul of life on the Earth. They are the ultimate wellspring of all activities on the planet. But human’s imprudent notion that water bodies are ceaseless asset to humanity has led to their substantial exploitation. Discharge of industrial, domestic and agricultural wastes and direct release of untreated sewage into water bodies are the prime cause of their deterioration. Physicochemical analysis of water is reliable means of assessing water quality. Present study deals with statistical analysis of physicochemical parameters affecting water quality of river Chambal running through Kota (Rajasthan).Correlation coefficient helps to determine degree of association between parameters while regression analysis aids to ascertain as to which factors affect each other significantly. Parameters were found both positively as well as negatively correlated with each other. Significant positive interaction was found between BOD and Temperature (R2= 0.8076) while BOD-Dissolved Oxygen ( R2 = 0.965) and Dissolved Oxygen (DO) – Temperature (R2= 0.786) showed remarkable negative interaction with each other.
