The proposed comprehensive study was accomplished to analyze the ecological phenomenon, heavy metals occurrence, and its significance. The spatial distribution of heavy metals in the sediments such as Cadmium (Cd), Cobalt (Co), Cupper (Cu), Lead (Pb), Mercury (Hg), Nickel (Ni), Zinc (Zn), Iron (Fe), and Chromium (Cr) of the Eastern coastline of India (ECI) was evaluated across 61 sites along the 1400 km stretch of the Bay of Bengal and the Arabian Sea coastline. The heavy metal concentration was higher for Hg (0.

The objective of the sediment and surface water characterization is to find the existing spatial and temporal intercorrelation. The sediment accumulation index (I), enrichment index (I), ecological risk index (I) and probability heavy metals (p-HMI) reveal the contamination status with Mn, Ni, Zn, Cr, and Cu showing permissible (0 ≤ I ≤ 1, I ˂ 2, I ≤ 150) to moderate (1 ≤ I ≤ 2, 40 ≤ R ≤ 80) contamination.

India is bestowed with huge amount of surface water resources. However, India lacks the quality monitoring of surface water and comprehensive management for sustainable surface water development. A new approach for indexing has been proposed to represent pollution due to heavy metals in surface water.
