HYDERABAD: Nacharam Pedda Cheruvu, which was recently found to be frothing with toxic foam and polluted with plastic waste, was visited by a delegation from Human Rights Commission. The delegation was accompanied by Dr Lubna Sarwath who had initially filed a petition on the pollution-related issues arising in the lake. She had specifically questioned the construction of a road/walkway by the Greater Hyderabad Municipal Corporation within the lake’s Full Tank Level.
