SEDIMENT IN WATER

Ikpoba River is the major recipient for municipal waste and industrial effluent in Benin City,samples of water were collected at five different locations in the river for some selected heavy metal analysis in order to determine the extent of pollution. Samples were collected in August to December 2021. Chemical analyses of samples river water and Dam was collected at predetermined sampling points were undertaken, the observations obtained were subjected to ANOVAand correlation analysis. Results obtained showed that each point source has its relative contribution to the overall degradation of the river water quality. The heavy metals were determined with atomic absorption spectrophotometry (AAS). From river water and dam the heavy metal concentrationwere found to be in the increasing order, fe>zn>cu> pb>Cd for all the five samples point collection as show in the result analysis. It also shows that the lead was not present in one of the point and Cadmium were not also detection in all of five sample. The analyses carried out also show the level of phosphate, nitrate, magnesium, pH, BOD,DO, electrical conductivity and turbidity in all the five stations and the turbidity was also notice to be relatively high. Most of the heavy metal determine were below the maximum permissible limit set by FEPA and WHO
