Microbes from human and animal excreta found above desirable limits in Yamuna
Subject : Environment
Context :As per a Delhi government report, levels of fecal coliform (microbes from human and animal excreta) is above desirable limits.
Concept :
- Fecal coliform is above desirable limits in all points tested in the Yamuna in Delhi with an exception at Palla where the river enters the Capital.
- The report also stated that in the absence of a minimum environmental flow (flow of water) it is very difficult to achieve even bathing quality standards of the river water.
- Minimum environmental flow for the dilution of the polluted water is required to meet the desired water quality levels in the river for bathing purpose.
- For bathing in a river, the desirable level of fecal coliform in the water is 500 MPN/100 ml or lesser, as per the Central Pollution Control Board.
- The level was as high as 1,40,000 MPN/100 ml (280 times the desired level) at Okhla.
Note:
- According to the International Union for Conservation of Nature, an environmental flow is the water provided within a river, wetland or coastal zone to maintain ecosystems and their benefits where there are competing water uses and where flows are regulated.
