Overview
- The latest DPCC uploads show faecal coliform spiking to 350,000 MPN/100 ml at Asgarpur in January before easing to 110,000 in February, far above the 2,500 limit.
- BOD reached 52 mg/l in January and 36 mg/l in February, compared with the 3 mg/l criterion for acceptable water quality.
- Dissolved oxygen fell to zero at four sites in January and at two in February, underscoring risks to aquatic life that require at least 5 mg/l.
- Compliance gaps persisted at sewage infrastructure, with at least 13 of 35 STPs failing standards in January and 12 breaching faecal coliform norms in February.
- DPCC samples water manually at eight fixed locations along the Delhi stretch, and the delayed uploads followed a March 6 complaint by activist Pankaj Kumar.
