The ground water is the important water resource for the developing nations including rural India. The increase in population, modernization, and alternate water supply schemes, the ground water getting polluted mainly due to the discharge of wastewater from residential areas, sewage outlets, solid waste dump sites, livestock rearing sites (e.g., dairy, poultry), and fertilizers and pesticides from farmers’ fields. The sludge accumulated in these water bodies may contain an appreciable amount of toxic metals that may leach to the groundwater and long-term use of contaminated water, either directly from these water bodies or the nearby handpumps or tubewells, can cause serious threats to human health. The water is drinking of highly polluted and chronic effect on people are genetic disorders, nerutoxicological disorder and carcinogenicity. This study investigated nine heavy metal (Fe, Pb, Cd, Zn, Cu, Ni, Cr, Co and Mn) contamination in the groundwater at ten stations in Karur block area, Tamil Nadu (India), and provides a sound case for examining the toxic metal accumulation in the water bodies
