After Bio-medical waste, it's now chemical waste that is threatening the city. A truck carrying huge quantity of chemical waste from a beverage plant was intercepted on Monday. It was the Mandur villagers who stopped a vehicle around 9 pm on Monday night and alerted the BBMP officials about efforts made to dump chemical waste illegally inside Srinivas Gayathri Resource Recoveries in Mandur South landfill. At 9 pm a truck looking like a diesel carrying tank was stopped by Mandur residents. BBMP engineers and officials from Karnataka state pollution control board visited the spot and filed complaint. The pollution control board officials collected the samples of the liquid waste that was stopped from dumping at the landfill. The wheels of the truck were punctured by the villagers and the vehicle got seized by police. The driver and cleaner of the truck are in Avalahalli police custody and the investigation is going on. It is said that the vehicle was coming from Patan Cheruvu, suburb located 25 km away from Hyderabad. "We have been told that the drivers admitted to have dumped similar waste in the landfill earlier also. Apparently they had come here many times, but caught only t his time, as the villagers followed up the huge tank that was looking like diesel carrying tank," said Narendra Babu, Mandur resident. Both the villagers and the BBMP have complained against the illegal dumping at the landfill. "It must be some kind of poisonous liquid that is filled in the truck. It looks like there is something burning inside. We are not sure about is there inside the tank," said Srinivas Gowda, Mandur resident. Speaking to TOI, a top official in BBMP said that the sample of the liquid that was prevented from dumping has been taken for further tests, by the officials of the pollution control board. The truck has still been stationed in front of the landfill. Due to the confusions raised among BBMP officials and police on Monday night due to this strange truck, the worst affected were the regular garbage ferrying trucks from Bangalore. "We could send over 150 trucks to Mandur last night. This affected the garbage clearance in the city on Tuesday morning, especially in Bangalore South," admitted a BBMP engineer.
