World Water Development Report, 2022 released by UNESCO, reveals that global use of freshwater has increased nearly eight times over the past hundred years and has been growing by about one per cent per annum since the 1980s. From the same report, we come to know that India’s water quality is poor ~ it ranks 120th among the 122 nations. Maintaining water quality conforming to the specifications prescribed by the Central Pollution Control Board (CPCB) has, therefore, become a challenging job, because unsafe water has severe implications for human health.
