The Classification of water quality in water pollution control numerous important steps. This is study is to classify the water quality of the Talar River basin using six monitoring stations. Multivariate statistical techniques such as cluster analysis (CA), principal component analysis (PCA) and factor analysis (FA) were applied for the assessment of spatial variations of the Talar River generated for years 2011–2014 by monitoring of 14 parameters at different sites. According to the results of cluster analysis, there were three quality groups in Talar River. PC and FA reduced the complex and voluminous data matrix into three main components, accounting for more than 80 % of the total variance. The first factor parameters TDS, EC, Cl, So4, Ca, Mg, Na, K, SAR and TH. The second factor Po4 and No3 And the third factor is HCo3.The results revealed that the major causes of water quality deterioration were related to inflow of industrial, domestic, Hospital and agricultural effluents into the ،Talar River.
