‘Ganga Air pollution Rise Declare Unscientific’

Folks collect on the banks of river Ganga in Varanasi, Uttar Pradesh.


Strongly rebutting claims of a considerable enhance in stage of pollution in Ganga in a report by Varanasi-based Sankat Mochan Basis, the Nationwide Mission for Clear Ganga stated such excessive ranges of biochemical oxygen demand (BOD) have by no means been reported for the river.

Questioning the capability of the Basis to hold out such assessments, the NMCG – a central company which has been implementing the federal government’s formidable Ganga rejuvenation programme – stated the excessive stage of BOD claimed weren’t “scientific in any respect” as such a state of affairs may result in sudden depletion of Dissolved Oxygen (DO) stage severely impacting aquatic life. Solely the Central Air pollution Management Board had the wherewithal to observe air pollution alongside the size of the river.

Referring to CPCB knowledge of the final six years, the Mission stated the DO stage has, in actual fact, been discovered to be inside “acceptable limits” of notified main water high quality standards for bathing. The BOD stage must be lower than 3 mg/L, DO must be 5 mg/L or extra and fascinating faecal coliform must be 500 MPN (most possible quantity)/100 ml with most permissible stage being 2,500 MPN/100ml.

The Basis has passed by knowledge collected by its laboratory at Tulsi Ghat in Varanasi and claimed that the BOD stage has elevated from 46.8-54 mg/L to 66-78 mg/L throughout January 2016 to February 2019. Equally, the NGO claimed faecal coliform within the river at Varanasi have elevated from 4.5 lakh (upstream at Nagwa) and 5.2 crore (downstream at Varuna) in January, 2016 to three.8 crore (upstream) and 14.4 crore (downstream) in February, 2019. Calling these claims “incorrect”, the NMCG flagged the scientific knowledge of the CPCB which carried out steady water high quality monitoring at two areas in Varanasi.

It stated, “Evaluation of water high quality monitoring knowledge of CPCB for these two stations situated on fundamental stem of Ganga in Varanasi for the month of January for interval 2016-19 signifies that minimal worth of DO assorted between 6.7 to 7.6 mg/L and indicated wholesome state of river.”
