Using remote sensing to track ‘galamsey’

The farm is irrigated with water from an old diesel-run pump, which draws the brown murky water from the contaminated river and sprinkles it on the neat row of pepper, tomatoes and okra.
Vegetables irrigated by this contaminated water could have traces of heavy metals and chemical residue, such as arsenic and mercury, that research by the Water Research Institute (WRI) has found in the river.
The World Health Organisation (WHO) points to the possibility of the chemicals causing a range of conditions, including cancers, heart disease, brain, kidney and liver diseases, muscle and general weakness.
