Center for Science and Environment's second volume of the seventh State of India's Environment report - Excreta Matters (71 cities: a survey), claims that India's cities are wallowing in their waste and the rivers becoming a dumping ground for it. In this report CSE profiles 71 cities on their waste water management capability and maps the state of groundwater and its sources. Each city is mapped to know more about its past, current and future water footprints, the amount of waste it generates and its disposal system.
