The poisoning of soils, rivers and the contamination of underground
water reservoirs with cyanide and mercury, poses a long-term risk to
public health.
For that reason, the inter-ministerial task force formed to halt the
activities of illegal gold miners, ought to consider how the
soil-decontaminating properties of biochar and vertiver grass could be
harnessed to repair some of the widespread environmental degradation
caused by illegal gold miners.
Repairing the harm caused by illegal gold mining could actually provide employment for the youth in rural Ghana.
