Write a note about water pollution of rivers of Odisha.

Water pollution in the rivers of Odisha, India is a major concern and has been caused by various factors. One major cause of water pollution in the rivers of Odisha is the discharge of untreated sewage and industrial waste into the rivers. For example, the discharge of untreated sewage from the city of Bhubaneswar into the Daya River has led to high levels of fecal coliforms and other contaminants in the water.

Another major cause of water pollution in the rivers of Odisha is the use of pesticides and fertilizers in agriculture. These chemicals can run off into the rivers and contaminate the water, leading to high levels of toxins and other pollutants. For example, the use of pesticides and fertilizers in the cultivation of rice in the Mahanadi River delta has led to high levels of pesticides and fertilizers in the water, which can harm aquatic life and human health.

In addition, illegal sand mining and deforestation have also contributed to water pollution in the rivers of Odisha. The extraction of sand from the riverbeds can cause erosion and sedimentation, which can lead to water quality issues. Deforestation can also lead to erosion and sedimentation, as well as reduced water quality due to the lack of vegetation to filter pollutants.

Overall, water pollution in the rivers of Odisha is a serious issue that needs to be addressed through proper sewage treatment and industrial waste management, responsible use of pesticides and fertilizers, and conservation efforts to protect the rivers and their ecosystems.
