Heavy metals (HMs) are a vital elements for investigating the pollutant level of the sediment and water bodies. The Murray-Darling river basin area, Australia is experienced severe damage to crop productivity, soil fertility, and pollution level. Murray-Darling river basin is the most effective area of Australia where agricultural productivity is increased the gross domastic product in the entire mainland. HMs contamination examination is conducted for eight sites selected for the basin. The inverse Distance Weighting interpolation method is used to identify the distribution of HMs. Four pollution indices i.e., Geo-accumulation index (Igeo), Contamination factor (CF), Pollution load index (PLI), single-factor pollution index (SPLI), and heavy metal pollution index (HPI) are computed. The Pearson correlation matrix is used to identify the relationship of two HM parameters. The results indicated that conductivity and N (%) are high using Igeo and PLI indexes for sites 4, 6, and 7 (2.93, 3.20, and 1.38), respectively. The average HPI is 216.9071 that indicates pollution higher level (100) of the Murray-Darling river basin. The highest HPI value is noticed in sample site 1 (353.5817). The Co, P, Conductivity, Al, and Mn are mostly affected by HMs in the Murray-Darling river basin. Those indices are indicating that the maximum HM pollution level in the Murray-Darling river basin. Finally, the results are showed that the high HM contamination level influences human health and local environmental conditions.
