High Coliform Levels Found in Delhi’s Yamuna River, Says DPCC Report
The latest water quality monitoring report by the Delhi Pollution Control Committee (DPCC) has raised concerns over pollution levels in the Yamuna river, with tests showing a high presence of coliform bacteria in the Delhi stretch.
Coliform bacteria are commonly found in the faeces of humans and animals, and their presence in water is considered an indicator of faecal contamination. A high coliform count generally points to the discharge of untreated sewage into a water body.
The DPCC report for January and February, which was uploaded after speculation over delays in releasing the data, also recorded elevated levels of biological oxygen demand (BOD). BOD measures the amount of dissolved oxygen required by microorganisms to break down organic matter in water and is widely used as an indicator of organic pollution.
As part of its monitoring exercise, the DPCC collects water samples from eight locations along the Yamuna in Delhi to assess pollution levels. The samples are analysed for parameters including biological oxygen demand, dissolved oxygen, chemical oxygen demand and faecal coliform.
The monitoring points include Palla, Wazirabad, ISBT Bridge, ITO Bridge, Nizamuddin Bridge, Okhla Barrage and Asgarpur.
