Notes:
An enhanced entry of heavy metals and metalloids into ground and surface water wasobserved in the historical hard coal mining areas of the districts of Zwickau and Lugau/ Oelsnitz inSaxonia, Germany. Heavy metals and metalloids like Mn, Co, Ni, Zn, As and Cd are enriched in thesurface waters of the district. This environmental impact is observed even though a recultivation ofsome of the dumps occurred partially already 50 years ago. In this study, preliminary microbial andgeochemical characterizations of samples from drilling cores in different depths of a dump site, ofsurface and ground water samples, and of sediments are described. Thiobacillus denitrificansappeared to be a dominating species in these moderately acidic environment especially where thereis nitrate infiltration and inflow, respectively, due to agricultural use of the adjacent area. Some ofthe sediment samples also contained high counts of iron- and sulfate-reducing bacteria due to theorganic detritus on the sediment surface
