Disposal of garbage into the river is one of the causes of river pollution. It will have a very bad effect on the river when all the domestic waste and rubbish is dumped into it. This will cause the river to be filled with waste materials and garbage plastic floating on the surface of the river water. In addition, the color of the river water will change to greenish and blackish from its original color which is clear. As an example that can be seen, in our own country, visible garbage residues suspended on the surface of the river and the murky color of the water on the rivers in urban areas as well as in the village area itself. As a result, human water resources will be polluted and aquatic life will be destroyed and cause unpleasant foul odors. Therefore, the dumping of garbage into the river can result in river pollution.

Greater scrutiny should be done on the causes of river pollution so that efforts to overcome and address the problem of river pollution can be carried out more effectively. Proactive steps should be taken by the government by organizing more awareness campaigns on the importance of river conservation and preservation. Even higher fines can be imposed by the authorities on those who carry out river pollution activities as well as monitoring the quality of river water in our country should be done regularly.
