The presence of sulphate-reducing bacteria in waters of the Coutts area, as indicated by chemical analyses, has been proved, and they have been shown to be absent from deep wells of the Turner Valley area. A limited number of tests indicates that they are absent from deep wells in the Wainwright area. They have been found in Idaho soils and in sewage.A procedure for proving their presence is described; pure cultures have been prepared, and some of their biochemical characteristics have been noted.The significance of the presence of these organisms in deep wells, soils and sewage is discussed, and some problems for further study are indicated.

AbstractAcid mine drainage (AMD) is a worldwide problem leading to contamination of water sources. AMD are characterized by low pH and high content of heavy metals and sulphates. The barium salts application presents one of the methods for the sulphates removing from AMD. Barium chloride, barium hydroxide and barium sulphide are used for the sulphates precipitation in the form of barium sulphate. Because of high investment costs of barium salts, barium sulphide is recycled from barium sulphate precipitates. It can be recycled by thermic or bacterial reduction of barium sulphate. The aim of our study was to verify experimentally the possibility of the bacterial transformation of BaSO4to BaS by sulphate-reducing bacteria. Applied BaSO4came from experiments of sulphates removal from Smolnik AMD using BaCl2.

Overburden Dumps

NA-processes can be enhanced for lignite overburden dumps, using dicarboxylic acid as a feasible substrate for autochthonic sulphate reducing bacteria. Sulphate reduction with simultaneous FeS/FeS2-precipitation occurs and immobilises SO4 2-, H+ and heavy metals connected with a decrease of the acidity. The used LC-OCD, HP/LC, isotopic and other chemical analyses substantiate sulphate reduction under technical enhanced conditions too.

Microbial Effects

After artificial recharging of groundwater some problems occurred, such as changes in groundwater quality, the silting up of recharge (injection) wells, etc. Therefore, the mechanisms of microbial effects on groundwater quality after artificial recharging were studied in Shanghai and the district of Changzhou. These problems were approached on the basis of the amounts of biochemical reaction products generated by the metabolism of iron bacteria, sulphate-reducing bacteria, Thiobacillusthioparus, and Thiobacillusdenitrificans. The experiments showed that in the transformations occurring and the siltation of recharge wells, microorganisms play an important role, due to the various chemical and biochemical activities. A water-rock-microorganisms system is proposed, and some methods for the prevention and treatment of these effects are given.
