Abstract |
|
The quantity and quality
of input and output water at the various stages of
mining is of critical importance in monitoring the
dynamics of mine water. This study was undertaken to
assess the
quantity and
physic-chemical quality of water sources for ore
processing, the process water pond and surface
waters in the Central African Gold (CAG) Mine
concession area. Water samples were analysed for
levels of some physic-chemical parameters: pH,
conductivity, total dissolved solids, iron, arsenic
and cyanide. Results indicate that the main sources
of water to the processing plant were the decant
water (55.10%) and thickener overflow (34.55%).
There was a general decline in water quality in this
study as compared to the baseline study and most
importantly deviated from levels prescribed by the
Ghana EPA standard and the WHO guideline for both
effluent discharge into the environment and drinking
water, calling for measures to ward off any possible
human and environmental health problems.
