Abstract. Concentrations of naturally occurring arsenic in ground water vary regionally due to a combination of climate and geology. Although slightly less than half of 30,000 arsenic analyses of ground water in the United States were =< 1 µg/L, about 10% exceeded 10 µg/L.

The Ashanti and Western regions are the major gold mining locations. The gold (Au) is associated with sulphide mineralization, particularly arsenopyrite (Griffis et al., 2002). The belief is that the Birimian formation has over ten times the average crystal abundances of gold and arsenic (Kesse, 1985).

It was by SIMS that the association of gold with arsenic in pyrite was first,13 This association has important metallurgical implications in that arsenian pyrite oxidizes faster than arsenicfree pyrite, and the rate of pyrite oxidation increases with arsenic content.
