Environmental organisations have come out against the reported move to revive a proposal to set up a mineral water-bottling plant in the buffer zone of the Silent Valley National Park.

When the proposal was made two years ago, the State government and the district administration had objected to it, with the District Collector submitting a report that the plant, planned on the banks of the Karuvarathode, a tributary of the Bhavani, near Mukkali, would affect the water table and cause serious ecological imbalance.
