Chaliyar River was in the news a few years ago because of the ecological damage caused by a pulp factory at Mavoor, that released effluents into the river and affected the marine life.
This factory has since closed down.

K. A. Rahman led the agitation for cleanup of the river, and inspired the formation of an anti-pollution committee, Paristhithi Samrakshana Samithi, in 1999.
