  • During high precipitation, infiltration of sulphates and chromates occurred, and subsequently when low precipitation, the aquifer without recharge becomes a confined environment favourable to a reduction of sulphates to sulphide (H2S and HS¯) by a complex biochemical process (a phenomenon called sulphatoreducing), due to the bacterial activity. Subsequently, this reduction results from the sulphur rejected (Khe´rici et al., 2009) by a sulphato-reducing bacteria (Desulfovibrio desulfricans), which can transform of Cr(VI) to Cr(III) which is a stable substance.
