Potential heavy metal pollution of soil and water

2019-4-1  Globally, small-scale mining is noted to be a major contributor to the pollution of water resources because it makes use of huge volumes of water thereby polluting the water resources (Cunningham et al., 2005; Owens et al., 2005). Most artisanal mining operators have no concession of their own and, thus, operates illegally.

Effects of small-scale gold mining on heavy metal

The effects of small-scale gold mining activities on heavy metal levels in groundwater were determined for the Lower Pra Basin of Ghana. Sixty five boreholes in 45 communities were analysed between January 2012 and April 2012 for the dry season and June and October 2012 for the wet season. The test for significance and the use of cluster analysis, a multivariate approach, clearly delineate Cu
