A Committee of Parliament visited the slaughterhouse in Meerut on June 10 to enquire if it was polluting the Kali Nadi river that flows through the city. A seasonal river that once provided irrigation and drinking water to 44 villages in Meerut district of Uttar Pradesh, Kali Nadi has turned poisonous. The slaughterhouse waste is only a part of the problem. Industrial effluents and municipal sewage also flow in the river.
