Abstract

Mining activities around the Boete Slimes Dam (BSD) of AngloGold Ashanti, Obuasi Mine, and its likely impact on surface water quality around the BSD, was investigated. Analyses of samples taken from Pompo stream and Kwabrafo stream and the confluence of the two streams draining the Boete Slimes Dam area showed that Conductivity, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Sulphate (SO42-), Cyanide (CN), and Arsenic (As) had values higher than EPA Guideline values,whiles Zinc (Zn), Lead (Pb) and Iron (Fe) were within acceptable range. Comparison of calculated and measured levels of conservative parameters at the confluence of the two streams using the mixing zone model corresponded well with a regression coefficient of between 0.79 and 0.93. The paper concluded that there is negative impact of the activities at Boete on the quality of Kwabrafo stream. The study also revealed that the company could save at least $1776 per sampling point annually since sampling at the confluence of the two streams could be suspended.
