Solutions to pollution of river Ganga
"Way back in 1986, Rajiv Gandhi launched the Ganga Action Plan. But years later, after much water (sewage) and money have flowed down the river, it is as bad as it could get. Why are we failing, and what needs to be done differently to clean this and many other rivers?
According to recent estimates by the Central Pollution Control Board (CPCB), faecal coliform levels in the mainstream of the river - some 2,500 kilometres from Gangotri to Diamond Harbour - remain above the acceptable level in all stretches, other than its upper reaches. Even in the highly oxygenated upper stretches, faecal coliform levels, though within acceptable levels, are increasing in places like Rudraprayag and Devprayag, suggesting inadequate flow for dilution."
"A comprehensive solution to the Ganga pollution lies in dealing with three problem areas: one, finding water to dilute and assimilate waste; two, finding innovative ways to check the growing amount of untreated sewage discharged into the river; and three, fixing the enforcement to stop industries from discharging waste into the river."
