The lake in Ooty, a major tourist attraction, now emits a foul odour , thanks to untreated sewage getting into it, now partly covered with water hyacinths. Garbage is also dumped on its bund. The Tamil Nadu Pollution Control Board (TNPCB) has made a study according to which the Ooty lake is one of the most polluted water bodies in the state. The study indicates that the presence of biochemical oxygen demand (BOD) in the Ooty lake has exceeded prescribed standards, at 11 milligram per litre (mg/l) as against the tolerance limit of 3 mg/l. Similarly data analysis of the water bodies in Poondi, Porur and Red Hills which serve as sources of drinking water supply to Chennai city reveal that they too are contaminated. The tests show the presence of coliform bacteria in samples of untreated water.
I am forced to put one question to the Board and get the names of at least some lakes and rivers in the state which are not polluted at all. One is indeed pained to see the status of rivers and lakes in the state. It seems to be nobody’s concern and everybody adjusts to such a situation. When are we going to use our resources and ensure planning for proper maintenance and beautification of lakes and rivers as we find in developed countries?
