Water quality of important rivers is crucial for ecosystems, human health, and economic activities. Key indicators include temperature, pH, dissolved oxygen, turbidity, and the presence of contaminants such as heavy metals and nutrients. Regular monitoring helps identify pollution sources and assess ecosystem health. Pollution from agriculture, industry, and urban runoff can severely impact water quality. Effective management practices, such as pollution control measures and habitat restoration, are essential for maintaining the integrity of river ecosystems. Protecting water quality ensures sustainable water resources for future generations and supports biodiversity.
