SALEM: A team of officials from Tamil Nadu Pollution Control Board (TNPCB) collected water samples from the River Cauvery near Mettur dam in Salem district on Monday, after fishermen found dead fish on the river banks.
“We conducted a check after receiving a tip-off about dead fish found washed out on the banks of Cauvery near Pannavadi. We were informed by local fishermen that the incident was due to water contamination in the river,” said M Murugan, Salem district environmental engineer of TNPCB.
He also said that the fishermen alleged that the water may have been contaminated after Karnataka let off untreated sewage and industrial effluents into River Cauvery.
On Sunday afternoon, fishermen discovered several varieties of dead fish in the river.
“The water had a foul smell and we suspected that it may have been contaminated due to untreated sewage and industrial effluents coming from Karnataka,” said P Ganapathy, one of the fishermen.
He also said the water colour has turned pale blue. The issue was immediately brought to the notice of the local council who in turn informed TNPCB officials who came in to check the situation.
Based on their request, a six-member team of officials including TNPCB district environmental engineer Murugan reached Pannavadi river bank on Monday morning. They collected samples from the river where the dead fish was found.
“We are sending the sample to the government lab for testing. We will soon be submitting a report to the government,” Murugan added.
