The study of underground contamination will be of immense help to researchers and environmental regulators to evolve and initiate mitigative measures. Peenya Industrial Area, Bangalore, India is considered to be one of the oldest and largest industrial areas in south-east Asia. Studies have been carried out to identify the parameters of contamination and their distribution with the help of the existing bore wells which have been analyzed for 20 parameters. The major general contaminants found exceeding standards are hardness and nitrates; whereas, hexavalent chromium and lead are toxic elements found exceeding the drinking water limits in some bore wells. However, the bore wells containing the parameters exceeding the limits were found highly isolated spatially in the entire area except an isolated presence of chromium in one pocket, thus indicating that the situation is not serious and can be tackled by initiating measures to control local stretches. Combination of parameters exceeding limit varied from bore well to bore well.
