Abstract
Phase-by-phase Post-remediation exercise of Duza twin village was conducted to determine the success of remediation carried out by Environmental Emergency Response Mission. Present phase in this report boarders on the children playground and the village market. Ten samples from playing grounds around the village market and general surrounding in the central of the village were made to assess possibility of contamination by artisanal mining exercises in the locality. Contamination Factor(CF) and Geo-accumulation index were used to determine extent of contamination and relate such to mining ore and extraction chemical used. GeoI values obtained for Pb and Hg respectively at the market location are 1.148 and 5.013, indicating moderate contamination by Lead and extreme contamination by mercury. The output of play grounds yields GeoI of 1.76 and 4.889 for Lead and mercury respectively. This results in similar range for both locations. In conclusion, the villagers have abused the remediation done by resuming ore processing at what- ever-small magnitude to escape the prying eyes of the village authorities.
