Watch: Sangareddy’s Nalla Cheruvu turns red as pharma firm releases effluents into waterbodyHeavy rains are allegedly being exploited by pharmaceutical and chemical companies in Sangareddy to discharge untreated effluents into local water bodies. In Bonthapally and Isnapur, tanks turned red and contaminated water flowed into paddy fields, causing health issues and panic among farmers. In one such incident, a major pharmaceutical unit in Bonthapally village of Gummadidala mandal allegedly released untreated effluents into Nalla Cheruvu at Domadugu on Thursday, turning the water completely red. On Friday, Tahsildar Paramesh and Municipal Commissioner Dasarath inspected Nalla Cheruvu and interacted with farmers. Contaminated water flowed downstream into other lakes, spreading a foul smell and causing inconvenience to residents of the Isnapur area.
