Mining waste may contain heavy metals which pose harm to the environment (AFRIM, 2012). The mines discharge the tailings into neighboring creeks; thus, downstream of the mines all streams are polluted to varying degrees (Briones, 1987). While the industry has brought economic benefits, it has also taken its toll on the environment (Briones, 1987). Mining waste may contain heavy metals which pose harm to the environment (AFRIM, 2012). The mines discharge the tailings into neighboring creeks; thus, downstream of the mines all streams are polluted to varying degrees (Briones, 1987). Therefore, it is critical to monitor the concentration of heavy metals.
