Environmental pollution by toxic elements has attracted global attention and that of the scientific community in specific. There is a constant threat to the quality of environment and the associated imbalance in the ecosystem due to relentless dumping of various types of pollutants. This research work is carried out to present a comprehensive view of the typical problems experienced by wastewater-fed Reservoir Command Area. This paper discusses the studies on transfer of seven heavy metals – Zn, Cu, Cr, Pb, Cd, Fe, Mn from various sources to the soil of the Reservoir Command Area, and thereby to the roots, stem, leaves and also fruits of the vegetation grown in that area. We also provide a brief understanding of the environmental effects of heavy metals entry into the ecosystem. The results and the analysis of the samples revealed that heavy metal contamination had occurred at certain locations/soil and in some vegetation grown in the command area. Some of the vegetation monitored were brinjal, mulberry, spinach, tomato, chilly, grass, drumstick, paddy and mango.
