Multivariate Statistical Analysis of Water Quality Parameters of Kakund River Basin (Lentic Ecosystem)

Abstract

Assessment of physico-chemical parameters of dam (Bandh Baretha) water is carried out to check the water quality. The Bandh Baretha is the main water reservoir which supplies water to the Bharatpur and areas near to Baretha. Total fifteen physico-chemical parameters like dissolved oxygen (DO), temperature, pH, BOD, COD, total hardness, turbidity, conductivity, chloride, phosphates, sulphates, nitrates, alkalinity, acidity, total dissolved solids (TDS) were studied to assess water quality of Bandh Baretha at selected sites located at Bharatpur district, Rajasthan. Water quality index (WQI) used to determine the quality of water and it conclude that water is not suitable for the consumption. By using Principal component analysis (PCA) and Hierarchical cluster analysis (HCA) show the degradation of quality of water. PCA generates 4 PCs which contributes (96%) in influencing the quality of Dam water.  Due to anthropogenic activities the quality of water deteriorate gradually which causes eutrophication.
