The study evaluated effects of flooding in Akiama  market  Bonny Island, Rivers State.  The purposive sampling was employed in the sample collection  of this study in two respective locations   of  Akiama  market. The  physiochemical  analysis  of  flood water  sample were analysed  for turbidity, ph value, appearance/colour,electric conductivity using  thermometer,ph meter and volumetric analysis. The bacteriological analysis shows the presence of staphylococcus aureus and Escherichia coli in the confirmatory results using biochemical screening. The physiochemical  parameters  were determined  using  methods  and  procedure  which include  tempreture,total dissolve solids(TDS),electrical conductivity and pH  within  the acceptable  range  and standard set  by World  Health Organization (WHO). The  bacteriological results  indicates  that flood water are not safe  for human health and  poses  health risk  to the inhabitants  of   Akiama  in Bonny Island.   Sensitization of the masses on the danger facing them will make them take responsibility and join forces  with  government tackle these menace. Regular cleaning of   drainage structures i.e. desalting of   drains maybe carried out once in a month should be encouraged.  The construction of   considerable size of drainage structures that will accommodate large  volume  of  water  will facilitate quick reduction  of  flood water  level  and discharged to a designated channel /canal /river bank.
