Representatives of the Periyar Malineekarana Virudha Samithi have submitted a letter to the State Pollution Control Board authorities to reinstall sensors erected to check water quality and air pollution level at the Periyar.
The equipment was installed as part of the functioning of the Periyar River Monitoring Station, that was officially inaugurated on Sunday.
According to the green activists, the sensors are placed at wrong places.“The sensor to assess the water quality should have been placed between the bund and the IRE (Indian Rare Earths Limited). Instead, it is placed downstream, almost 2 km down the river where the river water gets mixed with water from the backwaters. Thus we will not get an exact qualitative figure,” said Purushan Eloor of the Periyar Malineekarana Virudha Samithi.He said fish kill had occurred twice in the river, due to pollution, after the censors were installed a month ago.
“Both the incidents happened in December last year. But the sensors showed that the PH value and electrical conductivity were normal. Fish kill will not happen in that level. This itself proves that the figures shown by the sensors were not accurate,” he said.
As per the system, the sensors will check river water and air quality and the results will be displayed on a board installed on a traffic island -- FACT junction.
Purushan said the equipment to check air pollution was also installed at the wrong place.
“It should have been erected somewhere between the IRE and FACT-Island junction,” he said. The green activists said regular monitoring by the authorities is essential to prevent river pollution.
