JAMSHEDPUR: The health status of Subarnarekha river, which originates near Ranchi and is a major source of water for Jamshedpur’s residential area and industries, including Tata Steel, was found below average during a study by environmentalist and former professor of Ranchi University MK Jamuar.
Jamuar found that the pollution level of the river is much higher in places near big cities and towns. The pollution level increases with the respective population of that area.
The study revealed that the level of dissolved oxygen, which helps in the dissolution of inorganic substances in water, was low near Domuhani Ghat of Subarnarekha. The dissolved oxygen content here was in the range of 3.07mg/lt to 4.03mg/lt as against a desirable limit of 5mg/lt. The ph level was around 9.4 as against the 4 to 9 permissible limit of natural water body.
