Varanasi (UP):Being the largest river in India and revered for its religious importance, pollution in Ganga has been a focal point for a long time now. PM Modi had made clean-up of the Ganga as one of his key campaign promises in the 2014 general election.
His administration committed $3 billion in 2015 for a five-year project to clean the 2,525-km (1,570-mile) river remains heavily polluted despite being a water source for over 400 million people. Five years on and several projects and efforts later, the levels of pollutants in the river remain a point of concern.
