Evaluation of the Impact of Effurun Market Activities on Water Quality and Aquatic Sentinels in Warri River, Delta state

The impact of activities in the market affect water quality is a major problem for surface water, aquatic organisms and humans in the environment. the study shows the effects of Effurun Market activities on the water quality of the Warri River and its aquatic sentinels. Water samples were collected from upstream, midstream, and downstream sections and analyzed for physicochemical parameters, heavy metals, and microbial contamination and aquatic organisms (fish and water hyacinth) were collected .the results obtained for some parameters are pH ranging from 5.4-6.8, DO from 3.2 to 7.1, COD from 32.0 -309.33, feaecal coliform from 5.3-12.7. The results show elevated pollution levels, with lead, phosphate, and biochemical oxygen demand exceeding permissible limits. The findings underscore the need for better waste management strategies and policy interventions to reduce pollution in the Warri River.
