NEW DELHI: Even as India is making headlines with its rising air pollution levels, the water in the country may not be any better. An alarming 80% of India’s surface water is polluted, a latest assessment by WaterAid, an international organization working for water sanitation and hygiene, shows.
The report, based on latest data from the ministry of urban development (2013), census 2011 and Central Pollution Control Board, estimates that 75-80% of water pollution by volume is from domestic sewerage, while untreated sewerage flowing into water bodies including rivers have almost doubled in recent years.
