The findings have been a part of the report dated September 16, 2025 ready by the Kerala State Pollution Control Board on critically polluted river stretches in Kerala. Five of the monitoring stations are situated alongside the Periyar river stretches at Eloor, Aluva, Pathalam, and Kalamassery.
Samples have been collected from the Brahmapuram and Manakkakadavu monitoring stations alongside the Kadambrayar. The monitoring station in Chitrapuzha river is situated at Irumpanam. Samples are collected from these fastened places each month as a part of the monitoring programme.
The complete coliform degree was 7,900 MPN (most possible quantity) per 100 ml in samples collected from the monitoring station at Manakkakadavu. The CPCB has prescribed a most complete coliform degree of two,500 per 100 ml below the first water high quality standards for out of doors bathing.
On the Brahmapuram stretch, the full coliform degree was 2,600 MPN/100 ml. In the Periyar, the full coliform ranges at Eloor and Pathalam have been 1,500 MPN/100 ml and a couple of,400 MPN/100 ml respectively. At Kalamassery, it was 2,100 MPN/100 ml.
The CPCB’s National Water Quality Monitoring Programme performed between January and December 2024 had revealed that the water high quality parameters at 13 monitoring stations alongside the Periyar in Idukki, Thrissur and Ernakulam districts had didn’t adjust to norms.
The evaluation had revealed that every one 13 places failed to fulfill the first water high quality standards for out of doors bathing, as notified below the Environment (Protection) Rules, 1986. The parameters of non-compliance included dissolved oxygen, pH, biochemical oxygen demand, faecal coliform, and faecal streptococci, in accordance with the CPCB.
