Sewage discharge chokes Periyar
The Hindu
Updated status report on condition of river filed before NGT
An increase in discharge of sewage from cities and towns has resulted in the deterioration of water quality in the Periyar, according to the Kerala State Pollution Control Board.
The worsening water quality has been detected along the three river stretches that include Idukki, Idukki-Ernakulam border (Neriamangalam) to Aluva and Mangalapuzha branch in Thrissur district and Aluva to Eloor ferry, covering industrial areas in Eloor, Edayar and Kalamassery.
All results, except a few, are showing that the worsening of water quality is due to sewage intrusion particularly from cities and towns. Certain drains carry severely polluted wastewater from identified discharge points from town areas and unidentified sources in industrial areas, especially the Eloor-Edayar stretch, said an updated status report on the condition of the Periyar filed before the National Green Tribunal.
