The sudden decolouration of the waters of Meeananthalayaar, reeking with disgusting odour has caused concern among local residents and authorities. According to reports, the waters of Meeananthalayaar, a tributary of Meenachil River, developed the decolouration and stench within a short span of just 48 hours.
Local people found dead fish in large numbers, but ducks and other fauna that lived on atmospheric oxygen were not affected. Those who had taken bath in the water had complained of itching.
Authorities who collected water samples, however, said the source of the contamination could be a polder that was lying fallow for a long period, but was cultivated with paddy in the last season. The crop had submerged following heavy rain recently and had putrefied in the past one week. The demolition of a temporary bund nearby had resulted in the contaminated water flowing into the rivulet. The results of the tests will be available within a week.
