As industries have been closed down due to the lockdown, no effluents are being discharged into water bodies. As a result, the water of the Ganga in Rishikesh and Haridwar is now cleaner and less polluted.
After a long time, the water quality in Har-ki-Pauri has been classified as 'fit for drinking after chlorination'. According to the data available with Uttarakhand Environment Protection and Pollution Control Bard (UEPPCB), all parameters of water assessment in Har-ki-Pauri have improved after the lockdown.
Mr. SS Pal, chief environment officer of UEPPCB, said, 'There is a 34 per cent reduction in fecal coliform (human excreta) and 20 per cent reduction in biochemical oxygen demand (a parameter to asses the quality of effluent or wastewater) at Har-ki-Pauri in April. '
He said that for the first time in recent history, the water in Har-ki-Pauri ranked in Class A after the lockdown. Class A water has a pH balance between 6.5 to 8.5. The optimum pH for river water is considered to be around 7.4.
