New Delhi: Pollution in Yamuna has deteriorated with the level of faecal bacteria located at a record high of 14 times than what was three months ago.
This was disclosed by the December 2021 water quality status report by the Delhi pollution control committee (DPCC).
When the river enters the city, dissolved oxygen (do), the demand for biochemical oxygen (BOD) and Faecal Coliform is within the permitted limit.
However, at that time Delhi came out, high-level waste made Yamuna more polluted.
While the Coliform Faecal level on the entry is 1,400 MPN / 100ml (against a maximum limit of 2500 mpn / 100ml), the level at the exit is 2,800 times higher than the desired limit and 580 times higher than the maximum limit permitted.
In Asgarpur, which is the Shahdara and Tubhlaqabad meeting, the feces level in December 14.00,000 MPN / 100 ml of 4.90,000 in November and 94,000 units in October.
Level DO at PALLA Station is 14mg / L, while in Asgarpur it is nil from a minimum requirement of 5 mg / l.
The directors on the entry are 2.5 mg / L and 77 units at the exit against the maximum limit of 3 mg / l.
“Delhi has many fields that do not have the right sewer network.
More than 20% of the population has not received the right sewer network.
In addition, more than 80% of the waste treatment plant (STP) does not meet the standards,” said a DPCC official.
.
Experts state that the level of feces is high due to poor waste treatment and low environmental temperature.
The higher the level of faecal coliform, the higher the existence of pathogens causing disease in water.
Describe the existence of life, while the Board of Directors is the minimum oxygen needed by the river to break down and manage organic matter.
Ekolog Manoj Mishra said, “The presence of Faecal Coliform shows that STP is inefficiently Reaching River? Yamuna also has no flow Analysis by the DPCC Water Laboratory shows that there are 41 stps from the Delhi Jal Board where 35 is operational.
However, only eight adhere to the specified standards.
The manufacture of waste from 22 main drain channels is 3,273 million liters per day (MLD), while stps maintenance capacity installed is 2,715 MLD.
But only 2.182 MLD waste was actually treated.
