Ghana, renowned for its rich natural resources, has experienced a surge in illegal mining activities, particularly in recent years.

These illegal mining practices have left an indelible mark on the country’s river bodies, including the Ankobra, Pra, and Offinso rivers, causing severe pollution.

The Destructive Impact of Illegal Mining on River Bodies:

Illegal mining, also known as “galamsey” in Ghana, involves unregulated and unauthorized mining operations that often use harmful methods to extract minerals, such as gold and diamonds.


These activities cause significant damage to river bodies in several ways:


a) Chemical Pollution: Miners use toxic chemicals, including mercury and cyanide, to extract gold from ore. These chemicals are often improperly disposed of, finding their way into the river systems, contaminating water sources and aquatic life.

b) Sedimentation and Erosion: The clearing of vegetation and digging of mining pits lead to erosion, causing excessive sedimentation in rivers. This sediment chokes aquatic habitats, disrupts ecosystems, and alters the flow of water.

c) Habitat Destruction: The destruction of riverbanks and surrounding habitats for mining operations disrupts the natural balance of the ecosystem, leading to a decline in biodiversity and adversely affecting various species of flora and fauna.

Health Risks Associated with Polluted River Bodies:


The pollution caused by illegal mining in Ghana’s river bodies poses severe health risks for both local communities and the environment:


a) Waterborne Diseases: Contaminated water sources become breeding grounds for waterborne diseases such as cholera, typhoid, and dysentery, leading to a rise in public health emergencies.

b) Heavy Metal Poisoning: Toxic chemicals like mercury, used in gold extraction, accumulate in the food chain and pose a severe risk to human health. Long-term exposure can cause neurological disorders, kidney failure, and birth defects.

c) Agricultural Impacts: Polluted river water used for irrigation contaminates crops, leading to a decline in agricultural productivity and potential toxic effects on consumers of these crops.

The Need for Water Purification to Mitigate Health Risks:

Experts say to address the pressing issues arising from illegal mining and pollution of river bodies, urgent measures must be taken:


a) Strict Law Enforcement: The Ghanaian government needs to enforce existing laws and regulations related to illegal mining rigorously. Perpetrators must face legal consequences to deter future instances of illegal mining.

b) Community Awareness and Engagement: Raising awareness among local communities about the detrimental effects of illegal mining can help garner support for conservation efforts and sustainable alternatives to mining practices.

c) Water Purification Initiatives: Implementing comprehensive water purification programs is vital to make polluted river water safe for consumption and agricultural use. Advanced filtration technologies and water treatment plants can remove contaminants and heavy metals from the water.



d) Sustainable Mining Practices: Encouraging responsible mining practices and promoting small-scale mining that adheres to environmental standards can help minimize the ecological footprint of mining activities.

The impact of illegal mining on Ghana’s river bodies, such as the Ankobra, Pra, and Offinso, has been devastating, leading to severe pollution and health risks for both communities and the environment. Experts have called for urgent action to curb illegal mining activities, purify the polluted water sources, and protect the well-being of the people and the ecosystem.

By enforcing stringent laws, raising awareness, and investing in water purification initiatives, Ghana can mitigate the health risks associated with illegal mining and pave the way for a sustainable and cleaner future.
