Abstract: Viable counts of indicator and general heterotrophic bacterial populations were enumerated from 6 stations in Port Blair bay during different seasons. High counts of coliforms and indicator bacteria were generally recorded in the Aberdeen zone of Port Blair bay. Other zones in the bay showed few, if any, coliforms or indicator species during non-monsoon periods. During periods of intensive rainfall, the entire bay waters showed positive results for Vibrio cholerae, Vibrio parahaemolyticus, Streptococcus faecalis and Escherichia coli like organisms. Pseudomonas aeruginosa was mostly absent, except during a dinoflagellate bloom when counts as high as 102 CFU ml-1 were recorded. Viable heterotrophic bacteria showed a specific pattern of variation in which the numbers decreased progressively from the entry channel to inner portions of the bay. On the whole, results point to the large probability of coastal water contamination from rainwater runoff effects.
