Yamuna pollution surged last month with sewage at 400,000 units
The Yamuna River's pollution levels jumped sharply last month, with sewage indicators rising to 400,000 units, more than 150 times the safe limit.
Biological oxygen demand also spiked to 60 milligrams per liter, far above what is considered healthy for the river.
While things are a bit better than last year's peak, these numbers still raise serious concerns.
Lower Yamuna flow, untreated sewage persists
Less rain and weaker river flow have made things worse, dropping oxygen levels needed for aquatic life.
Water samples from across Delhi show heavy contamination.
Bhim Singh Rawat from the South Asia Network on Dams, Rivers and People (SANDRP) points out that untreated waste is still flowing into the river and says current fixes are just not enough.
With Delhi relying on the Yamuna for water, there is an urgent need to upgrade treatment facilities and protect this vital resource.
