This document provides an assessment of water pollution in the Ganges River from July 2013. It finds that the river experiences high levels of fecal coliform bacteria and biochemical oxygen demand (BOD), especially from Kannauj to Tarighat. Several urban centers and clusters of polluting industries discharge untreated wastewater into the river and its tributaries like the Ramganga and Kali. Diversion of water for irrigation also reduces flows, concentrating pollution. The report establishes a water quality monitoring network and presents data on pollution levels across Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal to identify polluted stretches and inform remediation efforts.
