Plastic and waste choke Porur Lake [ http://cmsenvis.cmsindia.org/resources/newspaper/details.asp?id=92825]CHENNAI: Even as one part of the Porur Lake supplies drinking water to the city, another, behind Iyyapanthangal not too far away, is a garbage dump. Residents of the Iyyapanthangal town, that falls under the Kundrathur panchayat union, have not found an alternative to dispose their waste other than to dump it in the now 240-acre Porur Lake, said to be only half of its original size.
