Protests against the leakage of oil by Chunnakam power plant into local water supplies continued on Thursday, with teachers joining residents to call for safe drinking water.
Carrying placards questioning the local government's actions regarding the oil leak, the protesters demonstrated by the Chunnakam Sivan temple.
"Local government, will the drinking water you provide solve the problem?"
"Test whether the water you provide to this region is clean!"
"Regional government, are you too complicit in reducing the Tamil population?"
