The picture of the black river containing the polluted water from the manufacturing unit and the city is going to change now. According to the preparations for the proposed Magh Mela in Prayagraj from January month, purifying the water of the Kali nadi is also included in the plan. The pollution control board (PCB) has started monitoring the river water.
Even though the dirty water of a manufacturing unit of the district does not flow into the Kali River, but due to the sewerage of the unit of Aligarh, Bulandshahr, its water is polluted. In January, in Prayagraj, a large number of devotees will reach to take bath in Magh Mela. After Kannauj, the black river flows into the Ganges. From the government level, the PCB has got directives to somehow clean the stream of black river which falls in the Ganges. PCB has now started monitoring the water of the Kali nadi.
Recently, thousands of fish were found dead in the black river. When the PCB examined the water, they found that the amount of dissolved oxygen has been reduced from a minimum of 5 to 2 while the amount of biological oxygen demand has increased from a minimum of 2 to a maximum of 12.
Ram Gopal, area Officer, Pollution Control Board said that we have started monitoring the water of black river and are looking at the possibilities of how to purify the water and how to balance the amount of oxygen in it.
Megh Mela is going to start in January month. The Kali nadi falls into the Ganges, so instructions have been received that monitoring should be done to purify the water from now onwards.
