A recent scientific study has highlighted growing concerns about the health of the Citarum River, particularly in its midstream area where hydroelectric power plants operate. The river, which plays a vital role as a source of clean water for local communities, households, industries, and renewable energy, is now facing risks from pollution carried in its sediments.
Researchers analyzed the physicochemical characteristics and the presence of potentially toxic elements (PTEs) in Citarum’s midstream sediments. The results revealed that while basic water quality indicators such as pH, Total Dissolved Solids (TDS), and Electrical Conductivity (EC) remain within safe limits, sediment samples showed alarming levels of contamination.
The study found a Pollution Load Index (PLI) of 8.523–10.904, indicating significant sediment pollution. This pollution is strongly linked to human activities, with the sediments containing magnetic materials and toxic elements from industrial and domestic sources. These findings suggest that harmful pollutants are being carried and stored in the riverbed, posing long-term risks to aquatic ecosystems and potentially affecting the stability of downstream hydroelectric power generation.
The researchers emphasized that continuous monitoring and integrated pollution control strategies are urgently needed. Protecting the Citarum River is not only crucial for clean water supply but also for ensuring sustainable energy from hydropower and preserving biodiversity in the region.
This research supports the goals of the United Nations Sustainable Development Goals (SDGs), particularly SDG 7: Affordable and Clean Energy — by safeguarding hydropower resources.
The message is clear: preserving the Citarum River means protecting both people and nature, while securing clean energy for the future.
