Distribution of sulfate-reducing bacteria (SRB) along with the depth, and correlation between sulfur and heavy metal in the layer of an open-dumping landfill site (95 m depth), Nanjido, Seoul, Korea, were investigated. It was found that SRB were widely distributed in all layers of the Nanjido landfill site with range 10<SUP>3</SUP> to 10<SUP>6</SUP> MPN/m<I>l</I>. Sulfur values were highly correlated with heavy metals concentrations of the landfill site in accordance with depth. Number of SRB, quantities of sulfur and total metals in suspended solids (SS), were 10<SUP>6</SUP>-10<SUP>9</SUP> MPN/m<I>l</I>, 2.71% and 3.15%, respectively. Moreover, values of those in sediment from the bottom of leachate catchment basin were recorded as 10<SUP>5</SUP>-10<SUP>8</SUP>MPN/m<I>l</I>, 2.60% and 3.29%, respectively. Therefore, it was assumed that heavy metals move as SS (floc) form from upper layer to the bottom. From these results it is deducible that formation of metal sulfide by SRB in presence of higher sulfur, may play an important role in insolubilization of heavy metals in Nanjido landfill site.
