THE ROLE OF MANGANESE REDUCING BACTERIA IN MANGANESE POLLUTION OF DRINKING WATERDAVINA, V. GONSALVES AND JOE DSOUZAAbstract Water samples were collected from the Selaulim Dam, Goa. This darn is surrounded by a number of mines exploiting manganese ore in its vicinity, from which the tailings are washed of into the lake feeding the dam. The samples were specifically analysed for manganese as it was feared that these mine tailings could raise the levels of manganese in the water to an undesirable concentration which could pose a health threat to the community consuming the water. Besides, microbiological analysis of the water samples the counts and activity of the manganese reducing bacteria in the filter bed material, used at the water purification project at the dam site, were also deten-nined. The analysis and water quality characteristics as well as the trends of the manganese leaching by the filter bed microflora were studied and are discussed.
