Officials from the Loss of Ecology (Prevention and Payment of Compensation) Authority took water and soil samples from Ramapalayam and Welpuram areas in Jadayampalayam and Thekkampatti in Mettupalayam on Wednesday.

In 2002, the villagers and farmers filed a petition before the Madras High Court stating that industrial effluents had polluted the water and soil quality in their villages. The pollution had resulted in water being unfit for human consumption and agriculture.
