Environmental Disaster in Zambia: Major Release of Toxic Waste from Copper Mining
On February 18th, an embankment collapse at a copper mine in Zambia released over 50 million liters of toxic wastewater into the Mwambashi River, causing significant environmental and health hazards. The incident has led to fish deaths, crop damage, and disrupted water supplies for local communities. In response, the Zambian government has initiated an investigation into the event, while BirdWatch Zambia raises awareness and calls for stringent regulatory measures.
On February 18th, a catastrophic event occurred in Zambia when an embankment, designed to contain wastewater from copper mining operations, collapsed. This incident resulted in the release of over 50 million liters of toxic waste into the Mwambashi River, which is a significant tributary of the Kafue River—one of the largest rivers exclusively within Zambia. The mine responsible for this disaster is operated by Sino-Metals Leach Zambia, a Chinese-owned entity located in Kitwe District, within the Copperbelt Province.
The contaminated effluent is believed to be highly acidic, causing extensive damage to fish populations, crops, and significantly disrupting the water supply in the nearby communities, particularly in Kitwe. Approximately 60% of Zambia’s 20 million citizens rely on resources from the Kafue River Basin for various uses including irrigation, fishing, and industry, heightening the potential public health risks associated with this disaster.
The Zambian government has confirmed the adverse effects of the pollution on agriculture and aquatic life, although the full extent of the damage remains uncertain. The spillage has contaminated local water sources with hazardous heavy metals, resulting in both environmental and health threats for communities that depend on this water for consumption. Additionally, there are concerns regarding unsafe irrigation and the accumulation of toxins within the food chain, which poses a significant economic risk to the regions dependent on fisheries, agriculture, and tourism.
This disaster adversely impacts the Kafue Flats Key Biodiversity Area, home to unique wildlife, including the endemic Kafue lechwe and over 450 bird species such as the Zambian Barbet and endangered cranes. The ecological significance of this region emphasizes the urgent need for effective management and conservation practices.
In response to this incident, the Zambia government has announced an independent investigation focused on the pollution of waterways, particularly in the Copperbelt area, where mining operations are linked to environmental degradation. BirdWatch Zambia (BWZ) has united with the Zambia Environmental Justice Coalition to voice their concerns regarding the ongoing environmental issues resulting from mismanaged mining practices.
Mary Malasa, Program Manager at BirdWatch Zambia, emphasized the need for prevention of such disasters, stating, “This is not the first time a disaster of this nature has occurred, and the level of damage witnessed—both to people and the environment—is unacceptable.” She stressed the importance of a proactive rather than reactive approach for environmental protection and called on the Zambia Environmental Management Agency (ZEMA) to enhance regulatory oversight and enforce stricter measures against future incidents.
This environmental disaster in Zambia has revealed the dire consequences of inadequate environmental management surrounding mining operations. The substantial release of wastewater into a critical waterway not only threatens local ecosystems but also the health and livelihoods of millions of residents. It underscores the necessity for rigorous regulatory enforcement and a proactive approach to environmental protection to avert similar future crises. The collaboration between environmental organizations and governmental authorities is vital in addressing and mitigating such occurrences.
