Despite the delays and challenges, it is possible to clean the Yamuna River in Delhi to bathing standards and achieve water quality to support propagation of aquatic life by 2025, experts have said. Treating all the domestic wastewater and industrial effluent and further cleaning it using in-situ techniques can help achieve the target, they said.    Delhi Chief Minister Arvind Kejriwal and Water Minister Satyendar Jain have on several occasions said the river will be cleaned to bathing standards by 2025. The Yamuna can be considered fit for bathing if biological oxygen demand (BOD) is less than 3 milligram per litre and dissolved oxygen (DO) is greater than 5 milligram per litre.
