Ludhiana's Buddha Nullah, once the centre of social life, has now become a 'source of cancer'. "Sewerage treatment plants are not working in the city, the toxic water flows into Buddha nullah water body, the massive inflow of untreated sewage and industrial effluents into the water body in recent years has now turned it into a source of disease like cancer," said a NGO worker, Jaswant Singh. "The toxic flows into river Sutlej, which is one of life line of Ludhiana city," the NGO worker added. The river Sutlej, which originates from Mansarovar Lake in Tibet, flows through Himachal Pradesh and Punjab. The mayor of Ludhiana City, Balkar Singh Sidhu informed, "Chief Minister Amarinder Singh, himself watching out the cleaning project of Buddha Nullah water body. I hope, it will become the old and clean water body again as it was earlier."
