Illegal mining activities known in Ghana as Galamsey has been a canker in Ghana for about a decade now.
Forest reserves and water bodies have been destroyed by these illegal miners in their quest to get gold.
The Galamseyers have left some major water bodies in brownish color and contaminated with chemicals.
Hemp Association of Ghana has advised the country to use phytoremediation to purify the water to make it safe for human consumption.
They suggest the government use marijuana plant in the phytoremediation because the water may appear clean after the Galamsey activities stops but the chemicals would remain unless they use plants like marijuana to absorb the toxics.
Phytoremediation technologies use living plants to clean up soil, air, and water contaminated with hazardous contaminants. It is defined as “the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless”.
