Knowledge on water quality and its assessment, is necessary for both human health environmental benefit. To account spatial distribution, surface parameters were analysed using integrated interpolation, geographical information systems (GIS) multivariate analysis. A total of 19 locations 13 indicators analysed, a duration six years (2018-2024). The study’s main objective was to assess the seasonal regional variations in index (WQI) Mahanadi River Odisha (N) pi, (S) pi , (O) (C) (E) y -WQI, Int w -WQI Multivariate Statistical tools namely Factor Analysis (F ). However, current investigation, pH, HCO 3 - Na + K Mg 2+ within permissible limits as per WHO standards. According this study, order prevalence ion concentrations signified follows: > Ca cations Cl SO 4 2- anions. analysis indicated that about 15.79% sampled area, affected by turbidity content, which highly unsuitable consumption. remaining area (84.21%) safe category water. Classification based represents most samples falls between good quality. Three noted result excessive TDS EC. In case over 84.21% fell into categories excellent, indicating suitability activities. Using results from model, reflects out samples, 16 suitable drinking. Whereas 2 polluted 1 seriously polluted, thus promotes unsuitability. Although there are several established techniques calculating WQI, study uses consider variety concerns cohesive manner. Meanwhile, y- 84.30% excellent whereas 10% 5% poor high category. Over 42.11% poor/very poor/not suitable, w- WQI diagram. Therefore, these approaches resembles precise comprehensive method comprehend relation pollution usage. later stage, factor ) can be applied lessen subjectivity dimension characteristics. It reveals first five principal components explain almost 95.61% dataset variation. This removes aggregation problems, weighting, opacity, biases seen traditional evaluation techniques. Fa suggested turbidity, TKN, primary determinants water’s amount organic released river influenced anthropogenic activity vicinity river. addition, dense habitation next manufacturing waste transported upstream downstream sources TKN urine faeces. given distribution geogenic occurrence, findings minimize uncertain causes offer insights regimes. They will also useful policy makers helping better plan, allocate resources, manage area’s potable supply.
