The Union government has decided to protect one major river in the State on the lines of the Ganga Action Plan.

The State government has been asked to submit a proposal to conserve one major river in the State, such as Periyar, which has been badly polluted, said K.V. Thomas, Union Minister of Consumer Affairs and Public Distribution. Talking on the sidelines of a national seminar on food safety, organised by the Bureau of Indian Standards here on Monday, Prof. Thomas said the issue of drinking water pollution should be addressed at the source of the pollution of the water body.
