Description 340-347
Distribution and occurrence of fecal
indicator bacterial in nine different locations along the inner to coastal
areas of Tapi estuary during three different seasons like, post-monsoon, pre-monsoon
and monsoon were analyzed for the period of one year. It
was found that monsoon was inhabited by the highest number of investigated bacteria,
while lower numbers of them were found in other two seasons. Concentrations of
fecal microorganisms in sediment were found to be significantly high. Overall
percentage occurrence for the enteric bacteria in water and sediment were
maximum accounted for fecal coliforms (64%), and moderate for Pseudomonas aeruginosa (22.2%). Higher
microbial populations were recorded in stations close to coastal areas and
inner estuarine as compared to middle and outer area of Tapi, while according to the analysis of surface water the highest
degree of pollution was reached on its estuary. Bacterial populations
showed strong correlations with biological oxygen demand and negative
relationship with salinity, indicating the dominating influence of human
activities resulting fecal pollution in the estuarine area.
