Heavy metals, at lower concentrations, have a high atomic weight and density which are toxic and can harm human health and the environment. The level of toxicity typically depends on the age, genetics, gender, the amount of exposure, and the level of immunity of the people. The aim of this study is to determine the extent of heavy metal pollution in Bangalore’s Peenya industrial area (PIA). Heavy metal concentrations were found in the following order: Cr > Cr+ 6 > Pb > Ni > Fe > Cd. The pollution indices, Heavy metal pollution index (HPI), and Metal index (MI) are used to measure the quality of groundwater based on the ranking. The mean concentration of HPI value is 845.1, which is significantly higher than the critical index value of 100. The percentage of groundwater samples that are over 100 index value is 83.33 percent, which is deemed completely unsuitable for purpose of drinking. The mean MI concentration was 27.1, and it was discovered that 73 percent of groundwater samples were “Seriously Affected” (MI value > 6.0). The findings indicate that the groundwater in these samples is extremely polluted and unfit for human use. It depicts the present state of the PIA in terms of harmful heavy metal pollution in groundwater. The effect of urbanization and industrialization on the study area has played a significant role in the deficit of groundwater quality.
