The trouble is the canal water mixes in the ecologically-sensitive Ennore Creek.
In a serious threat to life, loads of chemical effluents and waste oil are being clandestinely discharged into the Buckingham canal near Kattukuppam fishing hamlet at Ennore. The canal water, which is usually black in colour due to mixing of sewage, turned brown on Tuesday morning causing panic among fishermen. When Express visited the spot, it was like a mini oil spill. The water surface was filled with a thick oily substance and its traces were visible all along the canal for two km.
