Water in Mettur Dam has turned green due to mixing of untreated effluent and dirty water from drainages
In India, the Tamil Nadu Pollution Control Board (TNPCB) have inspected the water of River Cauvery. According to The Hindu, the water has turned green due to the mixing of untreated effluent and dirty water from drainages.
The mixing has added to the river pollution problem some Indian villages have due to the water spread area of Mettur Dam. The Mettur Dam is one of the largest dams in the country of India.
According to The Hindu, there was a heavy inflow of water into the dam following rainfall in the areas of the Krishnarajasagar and Kabini reservoir. The dam reached full reservoir level twice this season, forcing Indian authorities to release the entire inflow into River Cauvery for many days.
Now, stagnated water in the villages of Pannavadi, Sethukuli and Kottaiyur on both banks of the river have turned green. This has caused anxiety to the local people, especially the inland fisherman, according to The Hindu.
After the events, the water now has foul odor and has become unhealthy for the fishermen who go to the river daily to catch fish for their livelihood.
Residents now complain that the presence of polluted water may prove a major health hazard in the surround villages, according to The Hindu. The cattle are now facing the danger of falling ill, since they consume the polluted water.
TNPCB officials have collected samples of the water for testing in the government lab, according to official sources.
