ABSTRACT

 

The factor analysis (FA) was carried out in order to find out the distribution modes of different physicochemi- cal parameters along with heavy metals in water samples and to discriminate the different sources of pollution in river Damodar (India). Presence of heavy metals was detected in river water samples within the ranges of 0.00 - 188.75 μg l-1 (Pb), 0.00 - 65.09 μg l-1 (Mn), 0.00 -1452 μg l-1 (Fe) and 0.00 - 4 μg l-1 (Cd). High concentration of heavy metals along with sulphate was observed in the river Damodar at Chinakuri where the river receives mine wastes along with the wastewater from thermal power station. High concentration of nutrient indicates urban pollution at river Barakar near Barakar town. Thus, this study illustrated the usefulness of factor analysis for interpretation of complex environmental data set, water quality assessment, and identification of pollution sources. Study of factor analysis revealed that the industrial discharges, geogenic sources and natural factors strongly influence the water quality of the study area. The analyses revealed that the industrial discharges are responsible for the pollution of Pb, Fe and Cd in the river water along the Chinakuri industrial area.
