Days after the rotting carcass of a crocodile was found and removed from Powai lake,lab tests have shown that the lake water is not contaminated as feared,BMC said on Monday. The water quality has shown a marked improvement,according to the test results,stated hydraulic department officials.
The water samples were collected two days after the carcass was removed. The test results show that lake is in good condition, BMCs hydraulic engineer,Vinay Deshpande said.
An official,who collected the water samples and tested them in the BMCs laboratories,said,In fact,we have been conducting weekly chemical analysis on the water ever since the Powai lake beautification work kicked off. Our most recent results show that there is a marked increase in the dissolved oxygen levels,which is a good sign.
According to norms,the dissolved oxygen levels in lake ecology is expected to be at least three microgram per litre. The Powai lake is now recording six to seven micrograms per litre,which will give the marine life a boost, he said.
After the death of the crocodile,the water was tested for several parameters including dissolved oxygen and nitrate levels,the officials said.
Baqar Sheikh,general secretary of the NGO Maharashtra State Angling Association (MSAA),which has been studying and working towards improving the ecology of Powai lake for the past few years said,The death of the crocodile was natural and even the forest department has confirmed it. If there was any problem with the water,fish and other life forms would have died. On the contrary,the fauna of the lake is thriving. However,we have been suggesting to the BMC that it should demark a basking area for the crocodiles during the beautification project. This will ensure that the crocodiles dont intrude into human territories.
