Explanations:The Barulu River is located in the state of Assam, India, and is known for its high levels of pollution. The pollution in the Barulu River is primarily due to industrial waste and agricultural runoff. Industrial activities, such as the discharge of untreated effluents from factories and industries, contribute significantly to the pollution of the river. Additionally, agricultural practices, including the use of pesticides and fertilizers, lead to runoff that contaminates the river water.
Assam, like many other regions in India, faces environmental challenges due to rapid industrialization and agricultural expansion. The Barulu River, being a significant water body in the region, is particularly affected by these activities. The pollution levels in the Barulu River are higher compared to other rivers in Assam, such as the Beki, Kalang, and Bogdoi rivers, which are also affected by pollution but to a lesser extent.
Understanding the pollution levels in rivers is crucial for environmental management and conservation efforts. The Barulu River's pollution highlights the need for stricter regulations and better waste management practices to protect water bodies and the ecosystems they support. This knowledge is important for students preparing for competitive examinations, as it tests their understanding of environmental issues and geographical knowledge specific to the state of Assam.
